Reviewing the Caydo Automatic I-cord Machine

Hands up who doesn’t like icord? It’s an extremely versatile little tube that has many uses, amongst which is as a trimming or tie cord, or standalone as a thick yarn. Reach back to your childhood memories and you might have used a ‘Knitting Nancy’, or even a cotton reel with nails driven into the top to knit i-cord. You can hand knit i-cord with double pointed needles or even on two straights, with a bit of slipping and reverse knitting.

To my joy you can also knit it on a bed domestic knitting machine. On a double bed machine, or a single bed with a ribber attached, on each bed you cast on half the number of stitches that you wish to have around the i-cord, (for example, two needles on each bed will create a four stitch i-cord), then set one bed to slip and one bed to knit. This creates a tube of circular knitting. When using just a single bed, this is also an easy setting. Cast on four stitches, set your carriage to slip in one direction, and off you go. The slip pulls the yarn around from the last stitch directly back to the first needle and then you knit all four stitches again. After which the yarn goes back to the first needle again, and it makes a very nice little tube.

I have knitted i-cord by hand and on my knitting machine for many years, and at one point I purchased a hand-cranked, four needle circular i-cord machine, (I think it was a Prym?) which meant I could knit yardage very simply without blocking the use of my main knitting machine. I found the design to be quite awkward to use, so a bit later on I purchased another model, (it might have been Clover, but I think it was a French make). This is a much better designed piece of equipment, it fits well in the hand and is far more cheerful to look at because it is bright yellow and purple. The big plus is that any of these machines produce a consistently even i-cord. However, althouigh its faster than hand knitting, it still requires hand cranking.

Apart from these little i-cord machines I also have a plastic, twenty-two needle Addi circular machine. The Addi clearly knits a bigger tube that the little four-needle machines, but it works on the same principle with a revolving cylinder of vertical needles into which the yarn is fed through a statioary feeder. This means that the knitting coming out of the bottom of the machine turns with the cylinder of needles and can (and will) tangle.

The drawback with all these circular knitting machines described so far is that the knitting hangs down in the center of the cylinder and requires considerable weighting to make sure the stitches clear off the needles. Once the weights reaches the floor they stopped doing their job and unless rehung further up towards the cylinder, the stitches will miss-knit. If the knitted tube is turning at the same time as the weights descend, there is clearly far more potential for disaster to happen as the weight swings and the knitting twists. That is why the four needle i-cord machines and the Addi are my least favorite to use.

My pride and joy is a vintage, and very heavy, solid metal, circular sock machine. Although this still requires weights and they are very heavy weights, this knits in a slightly different way, with the feeder revolving around a stationary cylinder of vertical needles. This means that the knitting hangs straight down and does not twist as it is made. The advantage of this is that you only have to keep an eye on the weight, and do not have to untangle the knitted tube every so often.

Whilst working in industry, and at the University where I taught, I worked with what are called ‘strapping’ or ‘cording’ machines. The ones in use were small cylinder circular machines and fine gauge, so had tiny needle hooks and required thin yarns. These operated on the same principle as the CSM, but instead of weights, the cord winds onto a vertical frame which is synchronised to revolve at the pace necessary to keep tension on the cord as it descends towards the frame. This automates the process; the only human interaction is to change yarns and swap full frames out for empty ones. I suspect that the latest models will be almost totally automated with automatic yarn splicing.

Which brings me to the purpose of this post. At last! Because of the problems already discussed I was interested to try out the Caydo Automatic I-cord Machine. On close inspection, Caydo seemed to have addressed the problem of the knitting twisting by adopting the idea of a static needle cylinder and a revolving feeder, and overcome the weighting by laying the machine on its side and adding rotating cogs to tension the completed i-cord. I was intrigued as to whether this machine would prove to be as good as it looked in the adverts.

My verdict is that overall I really like this machine

I love gadgets, and this looked like a great gadget with thoughtful design which suggested to me an improved user experience and a positive practical outcome. Caydo kindly provided me with a machine to test and review, so that is where we are now. My video review is quite long, but I wanted to share the unpacking and assembly, (minimal) as well as explore the knitting process. My verdict is that overall I really like this machine.

It doesn’t like fancy yarns, but thats not uncommon

The machine won’t knit well with fancy yarns, and works with a limited range of yarn weights, but that is true of all domestic knitting machines. I met a lady the other day, and when chatting about the machine she was disappointed that it would not knit with chenille, but I am not sure that is a reasonable expectation as it clearly says in the manual what is and isn’t suitable.

I experimented a little, but as my aim was to review the machine as it stands, these were quite limited. I found that the harsher/firmer the yarn, the less the machine liked it. For example, I tried some crepe yarn and although it worked, the machine was not as happy as with less tightly spun yarn, until I helped by unwinding the yarn from the ball, the machine dropped the occasional stitch. I have had reports from other users that hand knit DK cotton works really well, but have not so far tested this out. The size of the hooks dictate the thickness of the yarn. Aran is listed as the thickest, but if not sure, lay the yarn in the hook and see if it sits there comfortably without being compressed.

Things I found that helped if the machine struggled:

  • manually wind to begin with and start with slow speed until you are satisfied that all is well
  • check that the yarn is in the tension disk correctly
  • watch for the yarn ball flipping over, this will tug on the machine
  • rewind the yarn onto balls that will pull-off easily, (if the machine has to tug at the yarn it stutters)
  • waxing as you rewind can help smooth the yarn
  • manually unwind the yarn before it gets to the machine if it is sticking to itself on the ball
  • listen to the machine, you can detect problems early by a change in rythmn/note

Be thoughtful when choosing yarns

The machine has weight, so does not shift around in use, and the case seems pretty robust. I am a little concerned about the rather delicate design of on/off/speed lever, as that is your ’emergency stop’ and might need to be turned quite rapidly, but so far it feels strong enough in use. The ‘knit/purl’ dial rotates when the machine is working, and yarn might get caught on this, so keep your work space clear of odd bits of yarn. I obviously don’t know how long the machine is going to last, and my guess is that the mechanism inside is largely plastic, (but I’m not taking it apart to find out). In my experience plastic cogs, such as those in ball winders are susceptible to strain and if worn may start to slip. The needles are metal, unlike the Addi, so should give stalwart service, as long as the latches don’t get bent. The needle ‘tricks’ in which they slide in and out are also plastic, but once again, provided they do not get burred or dented, they should wear smoothly, much as those in the larger, flat, plastic bed machines. If they do get dented with a sharp edge on one side of the indentation, the needle may catch on them as it slides in and out and could cause jams, (that is the voice of experience speaking). Over-thick and fancy yarns will contribute to all these potential problems, so be thoughtful when choosing yarns.

I was provided with a machine so that I could write/film this review, but have tried to be unbiased in my opinion and when describing my experience whilst using it.

A quick peak at my latest book

‘The Machine Knitter’s Guide to Partial Knitting: Seamless Pattern, Shape and Form’, is available to pre-order in the UK from Crowood Books, and online retailers. In the US it can be ordered from Blackwells.

Learn how to control short rows and create fab effects with this fascinating technique.

I’ve always been fascinated by short rows, or partial knitting as this technique is also called, so when the opportunity came to write a whole book about the technique I was super excited. The book opens with some interesting information about short rows to whet the appetite, the first chapter is about the absolute basics, so is ideal for people who have not worked with short rows before. The chapters progress through the different ways of using short rows; shown with examples, diagrams and written instructions. Some also have half scale sample patterns for practising the techniques which include more advanced uses, such as 3d shaping.. There are step-by-step instructions and each chapter builds on the knowledge of the previous chapter. The book ends with a chapter of patterns exemplifying the techniques covered throughout the book.

I so look forward to receiving my first copy!

Seeing up at Craft 4 Crafter’s show -updated

It’s been a busy day today setting up the Taunton Machine Knitting Club stand at Craft 4 Crafter’s exhibition in Exeter. The Club is pleased to have recently become a branch of The Knitting and Crochet Guild, making us part of the wider UK knitting community.

The display features work by most club members including lace, intarsia, knitweave and double jacquard. Throughout the three day exhibition members will be demonstrating different techniques such as cables, bobbles,  shaping and short row knitting.

The display is finally ready, and I am not  climbing a stepladder again today!

I will be giving a talk on Friday about my books, ‘The Knitting Book’, ‘Translating Between Hand and Machine Knitting’ and ‘Single and Double Bed Machine Knitting; the Designer’s Guide’.

The table will have to be large enough to fit four copies once my latest book, ‘The Machine Knitter’s Guide to Partial Knitting’ is published later this year.

Update

The show went really well. There was lots of interest in the club,  machine knitting in general and the Knitting and Crochet Guild.

The machines were a great draw
Yarn winding for those who bought yarn in hanks

Sock mending this evening

It’s a howling gale outside tonight, so the place to be is by the fire doing a bit of mending. The subject is a pair of socks machine knitted from my hand spun yarn. These sticks are like , ‘Trigger’s broom’ from Only Fools and Horses.

I plied the yarn from singles of Alpaca and Texel fibre, but did not include any nylon. Consequently, but after a reasonable amount of wear they have begun to thin and finally the stitches have burst. First of all the big toes went, and now the heels.

I had a little of the yarn left, but now it’s onto improvised and colourful mending…

The toes that were mended a while ago
Todays heel mending

I used one of those little mending looms for the toe repair, but the heels have been done ‘freehand’ using a technique from a 1970s mending book. I bought this useful book secondhand when a penniless student in the 80s, well before ‘slow textiles’ and ‘visible mending’ became a thing. Since then, useful book has helped me extend the life of many items for reasons of economy and necessity rather than fashion. Now my mending is on trend and it’s good to see the skill encouraged by a plethora of modern books on the subject.

Reforming ribs on a knitting machine

Reformin, or ‘latching-up’ single bed stitches into a rib structure is sometimes seen as far too time-consuming for a ‘fast’ activity like machine knitting. However, I quite enjoy the process and have written about it and made a ‘workshop’ video of working a 2×2 reformed rib here. I hope you find it of interest and useful.

What a lovely review of ‘Single and Double Bed Machine Knitting; the Designer’s Guide’

November’s edition of Machine Knitting Monthly has a great review of ‘Single and Double Bed Machine Knitting; the Designer’s Guide’. Amongst other nice things, they mention the broad scope of the book’s contents. I deliberately wrote so that it is suitable for any machine owner from Brother to Passap with lots of hints and tips to work on different types of machines. Thank you Machine Knitting Monthly!

Read excerpts from the review here.

A ‘wow’ review of ‘Translating Between Hand and Machine Knitting’

I found this review on Facebook ‘Machine Knitting’ group, and have to share it. I was so thrilled that this reviewer ‘got’ the book so thoroughly.

Book Review:
Translating Between Hand and Machine Knitting by Vikki Haffenden
☆☆☆☆☆☆☆☆☆☆ 10:10
“This book ought to be mandatory reading for every new machine knitter!” -me
“This book needs to be on every machine knitter’s manuals shelf, in pride of place, no matter if you use Silver Reed or Brother!” -me
“Where was this book when I was desperately trying to learn how to design lace/translate lace cards between Brother and Silver Reed?!?!” -me

This book is absolutely essential equipment as far as I am concerned! It starts out covering and comparing materials and equipment for knitting, both hand and machine versions. The pictures will blow you away and they only get better. Please, at this point, re-read the title. It does not state ‘pattern’ in the title.
Next it goes into stitch construction and compares hand and machine and final product of each. This book give equal time to both! It goes into yarn fiber types, yarn construction(spinning), yarn types (boucle vrs worsted). The details are absolutely in depth and extremely easy to understand with stupendously clear focused pin-pointed and highlighted photography and exemplary diagrams that compare every aspect of stitches, fabric, mechanics, of hand and machine knitting. It breaks down differences between brands when there are differences, and does not favor either. There are some references to Toyota and Passap, but the main info concerns Silver Reed and Brother. This covers every type of cast-on and cast-off that I could remember!! It isn’t a how-to… it compares them and shows some GREAT visuals of them on and off the needles. Refer to your manual for specifics on how-to cast-on and cast-off. Basically, this book compiled most of the answers to questions I have asked in the past, questions I have hunted down answers to, and questions that I hadn’t even thought to ask. It is utterly fantastic. Only the very last chapter goes into translating PATTERNS between hand and machine…

Buy it! Buy it NOW!
I can not say enough how much you need this book! How much I needed this book… now if I can just convince her to write one on Passap…
No! I have no affiliation with the author… I wish I could say I know her.

Since reading it I have replied, so let’s hope we can converse about knitting I the future.

‘Single and Double Bed Machine Knitting; the Designer’s Guide’

The advance copy of my new book arrived today, and you can see some pages from the book here.

Meanwhile here is a quick look at the book.

I have made a more in depth video introduction to the book, and if you would like to watch this, please keep on scrolling down the page.

Brother KH710 knitting machine refurbishment

Or

How I disassembled the needle selector plates of a KH710 and they lived to knit again

I have purchased one of these older, push-button knitting machines and at first look it was not in too bad condition. I have fond memories of these machines; Jones KH588 machines were the first ones I used at college when I started my degree in textile design in the dim and distant past. Apart from being cream rather than blue, the KH 710 is pretty similar to look at, and has the same functions and a lace carriage included. The KH710 is a little more streamlined as the two carriages have integral handles, not screw-on ones like the 588.

The 710 unpacked, de-needled and ready to be worked on

After a quick assessment it seemed to be complete and by the state of the brushes, I would say never used – but the main problems were sticking push buttons and, sadly, rusty needles. It looks like the machine may have been stored in a damp place as the needles were rusted underneath the sponge bar. This is not too bad, as the hooks and latches are not damaged so I planned to salvage as many as possible. The sponge bar itself was disgusting, melted, sticky and disintegrating into the bed, but this actually made it easier to clean it and re-line with a replacement sponge from Xena Knits. https://www.xenaknits.com/

The new sponge bar ready to go in

Before I tackled the sponge bar I removed the needles and put them into a jar of 10% citric acid for about an hour or so to see if I could shift the rust. The needles came out of the soak and after a thorough rub with wire wool and surgical spirit followed by a gentle oil they are not too bad. I’ve only had to swap a few few dire ones for fresh ones, and after a knitting test the salvaged needles knit fine. I’ve tried tuck, fair isle and slip in an acrylic 4ply and all went well.

Sample still on the machine, fair isle, tuck and slip all working OK

However, I now needed to take a look at the push buttons as some were sticking down. This started with number 8; it was very slow to rise up so the cancel button didn’t clear the selection and the needle was reselect – really annoying.

Brother apparently didn’t issue a separate service manual for the KH710, so I worked with the KH588 one I have, which was a good starting place. Although I have taken these machines apart before it was a long time ago, so I trawled the internet and found useful info on YouTube from the Answerladyknits and also from Vintage Knitting Machines. However, as with the service manual, these feature older KH585 and 588s which seem to be slightly different inside – particularly where the button module sits.

Whilst working on the machine I cleaned out the buttons, not that they were dirty, but one of the little springs was out of line, so had to be babied back into position. I may have done that whilst repeatedly testing the buttons for a clean return.

One of the parts that was difficult to get apart was the long wire that is attached to the plate which slides the button/needle selection across the bed. This is connected to the black numbered scale on the cover which shows the needle positions and has to be removed if you want to take the main back cover off. The screw is difficult to remove becasue there is nothing behind it, so no resistance to turn against. I managed to strip this and needed to use pliers in the end and a new screw was needed to replace the old one.

Since starting the refurbishment I’ve taken it apart several times and made a video which might help people with this model. I will put it on YouTube and link to it at the end of this post. The first time I removed the case, and sprayed the insides with LP1 to clean and food grade silicone to lubricate as recommended by Jack on the Answerladyknits, using both on the selector plates as well. After testing I thought the buttons were freer, but they reverted to sticking quite quickly, and had this had now moved to numbers 3 and 7. By now they were not miss-selecting but the slow return was annoying me! The physical needle selection with the set lever was also a little sluggish, so I decide the problem was probably with the needle selector plates inside the machine rather than the buttons themselves. All really frustrating. A lot of rude words were heard!

As I had taken the machine apart I thought it might be useful for other owners of 710s to see how I did this. Sadly I didn’t think of this until I was putting it back together again, but have put photos and video together to show most of my method, as you can see below.

This video explains how to disassemble and reassemble a Brother KH710 push button knitting machine. I have also made another video about unsticking sticky buttons on this machine and refurbishing rusty needles.

This video explains how to check over a Brother KH710 push button machine and the first thing to try to release sticky buttons. It also describes how to clean rusty needles and knitting to test the machine. For a more advanced fix, which includes taking the needle selector plates apart for extremely thorough cleaning, read on…
Garment pattern in tuck and stripe knit cotton yarn. Prepared in DAK 9 to be knitted on the KH710

At this point, thinking I had solved the problem I decided to knit a garment to test the machine. But whilst knitting this number 3 button began to get sticky and annoyingly slow to respond to the cancel button and pop up to neutral. It was only a little glitch, but enough to be noticeable. I also noted that number 1 and 2 were a bit slow as well. After I completed the back my frustration with the buttons overcame me and the machine came apart again.

This time I decided to concentrate on the needle selector plates. There are eight of these plates which are thin metal strips with tabs along the top, longer edge that look a bit like castle battlements. These are sandwiched between two ‘L’ shaped nesting metal needle selector plate holders in one complete assembly. Each thin plate has differently positioned, evenly spaced tabs which correspond to a push button and a needle. These plates are held in the needle selector plate holder with pins and screws and slide across each other, so must be clean and smooth without any gunge between them.

Close up of the selector plates when out of the machine, but still in their holder. In this image, plate one, which responds to button one is at the back, plate eight, which responds to button eight is at the front. This positioning depends on the way in which the needle selector holder is viewed.

The way these plates work is rather neat. Each has a different sequence of holes, (round and elongated) along their length. They also have as series of slots shaped like extended ‘U’s. When the plates are stacked together in the holder in the right order the holes overlap, forming a set of eight small holes that line up with the control wires, (or feelers) that come from the eight push buttons. When a button is pressed its feeler wire moves to the side, sliding the corresponding plate so that the tabs are inline with the needle number (1-8) to be selected. However, the plate is still too low to touch the needle butts and this is where the pins and slots come into action. When the plates are stacked in the holder, the slots fit onto the pins. As a plate slides, the slot travels over the static pin and the plate rises upwards as it reaches the higher side of the ‘U’. This lifts the tab high enough to align it with the butt of the correct needle. As the set lever is pulled the whole plate assembly slides forwards and each selected plate tab pushes the needle in front of it as it moves forward.

So I bit the bullet and stripped it down a bit more. To start with I unscrewed the white nylon zig-zag arm and removed the metal plate that slides the button selection/assembly along the bed from position 1-8. You can see how to do this in more detail in the earlier video. This allowed me to see the needle selector plates more easily. At this point the needle selector plates were still inside the machine. Next I tried taking out the three little screws on the base of the plate holder assembly which hold the right angle plate-holders together. This allowed me to open them up so that I could slide a scalpel blade between the plates to open the gaps, and squirt more LP1 into the gap and clean out any debris. I then stood the machine at 45 degrees so that the fluid would run out from between the plates and left it for an hour or so. After this the sticking improved, but didn’t go away. Plus I had a pool of lubricant in the lid of the machine that I had sat the end in… messy and smelly.

Next I decided to remove the plate holder itself. This involved removing the button assembly as well. Horrors! I was entering the dark side…

All the sensible advice is to avoid disassembling the needle selector plates, but I could see that there was a stringy, viscous substance between them preventing them sliding across each other. I really needed to clean this off! My envy of videos showing effortless button pressing on other machines spurred me on.

The selector plates being taken apart. Note the ‘U’ shaped slots and the labelling of the parts. These plates are shown with the tabs at the top, as they would be in the machine.

It all came out quite easily, which was a surprise to me. The whole needle selector assembly is mounted on three raised-head screws that enable it to slide from left to right but there is a long, screwheaded nut that fits through a metal blocking plate attached to the button assembly which stops it sliding totally off these mounting screws. I had to remove this long screwheaded blocking nut to remove the holder from the machine body. The button assembly had tocome out as well, so before going any further I carefully unscrewed the two large headed screws that hold it in place on the metal slide its rear. Once that long headed blocking nut was removed, and with a little fiddling the whole needle plate holder could be slid to the ‘keyhole’ end of the three long screw slots and holder and button assembly lifted out completely. The button wires could then be slid out of the plates and put to one side. Mine was clean, but if yours needs cleaning do that after cleaning the plates and before reassembling it all.

The long screwheaded blocking nut fitted underneath the needle selector plate holder. It fits through that metal plate so that the plate stops against a bracket, preventing the needle plate holder sliding all the way out of the raised-head mounting screws.

Now it was easy to take the plates apart. BUT, if you do this, take the time study how it all works before starting. Take lots of photos as you disassemble, and label each part clearly in permanent marker BEFORE moving it. Then if you knock things over, or have to leave the machine for a period of time, you will know how it goes back together again.

My order of work, once the holder was out of the machine, was a follows:

Remove the inner plate holder

Label L and R end

Remove all the plates in one go and lay them parallel to the inner with the tabs facing away from you

Label the outer holder L and R.

Carefully separated the top needle selector plate

Label it on one end. I used ‘L1’ meaning it is push button 1, and that that end matches ‘L’ on the holders. All others followed as ‘L2’, ‘L3’ etc. One is the plate at the rear of the holder, eight is the one at the front.

Wipe the plate clean of oil and dirt and polished both sides

Replace it onto the pins in the outer holder, matching L to L.

Repeat with each plate, making sure to label them methodically.

Test that the plates slide smoothly.

Screw the holder back together.

Phew, time for a cuppa now!

With a little fiddling the button wires went back into their respective holes. I found this easier to do with the assembly held so that the wires were vertical.

Sliding the button wires back through the selector plate holes

Because that long screwheaded blocking plate nut is really awkward to replace in situ I replaced it in the needle plate holder before putting it back into the machine. This meant that I had to remove one of the raised screws which the holder slides on otherwise the blocking plate didn’t fit correctly and the holder would not slide. These raised screws attach through to the set lever mechanism, but temporarily removing the left hand one, (button side of the bed) meant that I could slide the needle selector holder and button assembly back in place so that the blocking plate and nut fitted together correctly and did their job. Just remember to replace and fasten this screw before you move anything else.

A quick test showed that the buttons were zapping away cleanly and efficiently and that the needles were selecting with ease. After that is was plain sailing, and the machine went back together as shown in the original videos without any problem.

I hope this might help anyone who wants to take a Brother KH710 apart for repair. I certainly could have done with a bit of help.

I will put this into a pdf at some point and upload it here.
