Members iron1951 Posted October 2, 2019 Members Report Posted October 2, 2019 I need a belt for my 108w20. The hand wheel pulley and the bobbin threader pulley look like they take round belts, not V-belts. Where can I get round belts? Any other options? At this time the 108w20 is not in a table so I don't know belt length. Is it possible to make up a belt, to a custom length, like they do for the singer treadle machines? Thanks Quote

Members Bert51 Posted October 2, 2019 Members Report Posted October 2, 2019 You need a 8mm (3/8) wide M type V Belt, what we call a V belt that you use on your car is a 1/2 V belt. Although you can use an automotive 1/2 inch V belt, it will sit to high and may rub on the guard, if fitted. Bert. Quote
Members iron1951 Posted October 2, 2019 Author Members Report Posted October 2, 2019 I am familiar with the 3/8 v belts. I use one on my consew. But I have two "neat looking" bobbin winders that I don't think will work with the v-belt. Quote
Members iron1951 Posted October 2, 2019 Author Members Report Posted October 2, 2019 I forgot about McMaster-Carr. They have round belts but they ain't cheap. Quote
Members Matt S Posted October 2, 2019 Members Report Posted October 2, 2019 These machines were built for round leather belting. You typically buy a length, cut to size with a knife and insert a heavy wire staple to secure. Available from most industrial sewing machine suppliers, and eBay. The modern equivalent is a textured polyurethane, which again is sold by the length. This is secured by melting and fusing the ends together, then trimming any fillet when cooled. I think it works better than leather but comes in bright colours, which look jarring on a beautifully japanned vintage machine. The good thing about round belting is that you can keep a roll on the shelf and make up whatever length you need instantly. Quote
Members iron1951 Posted October 2, 2019 Author Members Report Posted October 2, 2019 Thanks to all. Not sure which route to go yet. Waiting upon needles. Quote
Members Bert51 Posted October 3, 2019 Members Report Posted October 3, 2019 These Bobbin Winders are made to use with round leather belt and I run several of my machine with leather belts and no problems. I have one old Singer 16K113 setup with a V belt and the same type of Bobbin winder and it works okay for me. Just took a little to set up, but works okay. Bert. Quote
Members blue duck Posted October 3, 2019 Members Report Posted October 3, 2019 If you decide to build one, Wawak has the round leather belting. Quote May God Smile on you today.
Members iron1951 Posted October 3, 2019 Author Members Report Posted October 3, 2019 Thank you. Never heard of Wawak before. Going to bookmark it. Quote
