Singer 401g

A while ago I posted about this new acquisition. I’ve not been able to use it much recently as I have two knitting machines up. I’m busy writing my latest book on machine knitting which has to take priority.

Before going any further I must point out that the machine now had been rewired and has a new for pedal, so is not as precariously wired as in the photo any longer.

However, I need to plant out my tomato plants and have to make grow bags for them, so it out came! I’d forgotten how great it is to sew with. It went through six layers of hessian without batting an eyelid. The big ‘but’ was that I had forgotten it’s little foibles.

When start a seam on my Bernina I go forward, back and then sew the seam. Singer-babe is different, she needs special measures. To prevent that worrying sounds of jammed threads in the bobbin and a jammed feed, I’ve learned to drop the foot 1cm or so into the seam, sew backwards and then go forward. The manual clearly explains this point, but who reads manuals? Once I remembered this, all went well.

I’m still annoyed that I can’t get her to use metal bobbins. Plastic ones were in the box when I got the machine, and I really dislike these. So I invested in several metal ones to fit, but they don’t work well at all. I’ve adjusted bottom and top tensions to try to get a good stitch, not nothing works. So it’s back to the plastic ones before they all go out the window.

Anyone else have this problem, or have any advice to offer?

UPDATE. May 2021


I the problem I was having with the bobbin was that the thread was not looking over the bobbin, but catching around it instead. I found a video by Andy Tube on You Tube which explained how to check the thread gap on the bobbin case, which prompted me to check mine. Oh yes, it was way out.

I can see how this happens; the black spring that holds the bobbin case in place has a tempting little finger that looks as if it should be used to lift the spring up. BUT DON’T. That is clearly one of the ways it can get out of line. So with the help of a feeler gauge and Andy’s helpful video I think I have largely fixed the problem.

Andy suggested that the bobbin case might be worn, and that also might be contributing to the thread dropping underneath. So I have ordered a new one. After all, it is probably 50 years old, ( this machine was made in the late 1950 early 60s. Maybe it’s had a new bobbin case in that time, but maybe it hasn’t!

I still haven’t solved why the zig zag stitch missed sometimes, that is my next challenge.

UPDATE July 2021


Ok another update.

I think the zig zag daily is because the needle arm is slightly out of line. Another Andy Tube video shows how to fix this, so that my next challenge.

Another new sewing machine – my Singer 401g

I have been toying with the idea of buying a Singer slant shank machine for a while, and during lockdown I took a punt and bought one reasonably local on eBay. Not the smartest move you might say, sight unseen and all that. I spent quite a time scrutinising the photos very carefully, read up about the machine, and asked lots of questions of the seller. Call it a treat to myself.

Updated with some photos just now, 16:00 4th July

Above, as it arrived, a bit grubb

And below, after a good clean up

Finally I went to collect it – social distanced collecting methods in use and no stopping en route. Its outside is a bit grubby, but its working and has all its accessories down to the lint brush and set of screwdrivers. Its obviously well used, it was owned by a dressmaker before, but I would guess not used for several years. However, its got service labels and having all its accessories indicates to me that it was well cared for and valued. It came in a drop down table, which was perfect as wanted one in a table, but not a massive cabinet.So far I’ve opened it up and cleaned its insides, removed as much old gummy oil – or as I can reach – and given it a thorough oil with light sewing machine oil. The double direction pattern dial was gummed up, and this gentle cleaning and oiling helped to loosen it up so that I could (very carefully) encourage it to move, and now it works freely. Its fascinating to see how the selection mechanism works, not that I am an expert at mechanics, but I can see the little paddle moving and the rise and fall of the selector post (probably the wrong name). I am itching to try out all those amazing built in patterns. I can’t right now as you will see in the next paragraph.The original clam-shell foot pedal is with it, and it did work – sporadically. After a while there was a nasty smell (reminded me of when my Bernina 1030 went into melt down, and when my Brother 950i knitting machine and very, very vintage Kenwood Chef did the same) and the machine would not stop running. Luckily the plug was close to me, so I whipped it out to the socket before any damage was done.My clever son opened the pedal and told me I should have cleaned that out (didn’t even think of it, sorry), and then he replaced a blown capacitor – he is pretty nifty at this and has a stock of electrical bits. The pedal now works – but the connection from the pedal lead to that ‘banana’ plug is dodgy. In addition some of the old plastic has broken away inside the pedal and the plug has a chunk missing which worries me. I’m not confident around electricity having had a few experiences that unnerved me, (see above). He offered to repair the lead and plug (he thought Sugru) and will in time, but I decided to order a replacement so that I could use the machine until then. I will compare them to find which gives the best speed control as some reports say new ones are not as sensitive.The motor seems OK, and my son will clean it at some point. So far the machine has displayed a lovely straight stitch – equal if not better than my Bernina 1030, and far better than the Jones 125.I did hanker after a Singer 411g or 431g but I think the 401g will satisfy me. It was only the chain stitch of these I wanted, but reading about it it sounds to require lot of fiddling to get it right and so that do you leave the machine set up just for that? Seems a waste to me, so I’ve let that wish go for the moment. I also think I remember that my Janome Coverstitch machine will do chain stitch, so maybe that is something to explore. I’m not even sure why I want chain stitch – I’m just a machine nerd (maybe?).Want this space for more chats about the Singer 401g that has joined my machine stable. Its going to be sewing frontline masks once the new pedal arrives.
