toxo Posted October 30, 2024 Report Posted October 30, 2024 I'm certain I'm not the first to bring this up. Seems enormous on my 341 and because I use a variety of weight leather including upholstery weights and sometimes sew close to the edge the hole is a problem. How can I make it smaller? Solder? Maybe ram a thick copper rivet down there and re-drill the hole? Any other suggestions? I'm about to Whatsapp my Chinese lady to ask if the company does one with a smaller hole but I'm not holding my breath. Quote
Members DieselTech Posted October 30, 2024 Members Report Posted October 30, 2024 On my class 441 machine I bought narrow feed dogs & needle throat plates for it, because of this problem. I do not know if they are offered for the class 341 machines. The narrow feed dog & throat plate fixed/solved a lot of my problems I was having. I'm sure you can modify them to your needs if careful.

I soft soldered it and it filled it nicely but it's a straight bore hole so didn't stick. Never used silver. I know it's harder/higher melting but will it stick? Quote

If a magnet don't stick it is probably stainless & will require a good flux for stainless & a high percentage silver solder. Thanks. Edited October 30, 2024 by DieselTech Quote

Magnet sticks so must be a mild steel. Been meaning to try silver for a while now. I have two large compasses?/dividers and the bit that holds the pencil has fallen off both. Tried soft solder but didn't work so I can see some more learning on the horizon. (If I can find the bits that fell off). Quote

A lot of times for me the flux is the key to good solder job. Quote

Make sure to get flux too when you get silver solder. A lot of times for me the flux is the key to good solder job. Seems we are both boy scouts. I also like to be ready for all eventualities. I will go out for some silver later but I found some "JB Weld" and without much hope I stuffed the hole with that and blow me it seems to have worked. I got impatient and drilled the hole before it was fully hardened and so is a little bigger than I wanted but much better than before. Got some sewing to do today but if alls well now it's fully hardened i'll bung some more in there and do it again. I've asked China to send another feed dog to modify. Quote
toxo Posted November 8, 2024 Author Report Posted November 8, 2024 Update! The JB Weld didn't work very well. It looked ok but after using it the thread wore through it a bit so now I have some silver solder I'm going to do it again. Just wondering what can be used as a kind of resist to block up the hole and stop any going straight through? Quote

If you use aluminum foil make sure to fold it over multiple times to make it a thicker piece of aluminum foil. Edited November 8, 2024 by DieselTech Quote
