This is part two of a two part video series where I look into getting this cute little industrial overlocker from the 1940s up and running.
In part 1, I assess the machine head and give it a good look over, lubricate and check the blades.
You can find part 1 here - • Sewing Machine Archaeo...
In this part I come across an issue with the blades and thread the machine to see if it will form a stitch.
A good customer of mine has recently purchased this industrial Singer overedger head and wants me to see if I can get it stitching. The original table and motor is long gone unfortunately but I think we can at least test it by hand to see if it forms stitches.

The incredible work that went in to building machines like this, without a computer, is amazing!

Thank you for another interesting video! The old Singer company doesn't really exist anymore, and calling the company that owns (and sells modern machines under) the Singer brand name to get spare parts wouldn't do you much good... But copies of several versions of the "81" were until recently made in Russia, and they are still made in India and China, AFAIK, so there may be some spare parts available from other sources. However, I can't find the screw in question (spare part number 336) online, and unfortunately it's not in the ISMACS list of screws for Singer industrial machines either. If you have a lathe, cutting a new screw a bit oversize is probably better and a lot faster than finding a replacement. If you don't have a lathe, turn the "thingamajig" it screws into upside down and drill and tap a new hole for an available screw from the other side! There seems to be lots of options for threading the different versions of the "81". Documenting them all would be an heroic feat, if someone were brave enough to undertake it...

Thanks. I'm just going to try drilling the existing hole slightly over size and tapping in to an appropriate metric thread size and using an off the shelf screw. It may not look original but my customer doesn't care about that, as long as it works.

@@InStitches Just make sure you have enough material left on he sides of the hole after drilling and tapping, it looks pretty thin in the video! Best wishes, I hope it works out!
