Heaviest Thread for sewing leather on Singer 201

[reidthaler]

I have a singer 201 (circa, 1947) sewing machine and want to know what is the heaviest thread that I can use to sew 4 ounce (1/16 inch thick) together.

I would like to #92 and if you have some insight thanks. If so, I think the 110/18 needle would work. If you recommend only #69 thread, should I go with the #16 needle?  Most that I've seen online says most home sewing machines max out at #69 thread.

 

Thanks,

This kind of question is nigh on impossible to answer because there are so many variables to consider. Apart from the usual, on an older machine the hole in the stitchplate might be too big and if the presser foot doesn't hold it the needle will poke it down the hole on  thinner material. I've learned that each machine is different and the only way to find out is trial and error I'm afraid. Find some cheap thread/needles and experiment. A rough check on needle size (because thread is notoriously marked mysteriously or not at all) is the right size needle should slide on the thread when held at 45 degrees. Good luck!

Thanks all.  The message I seem to get everywhere is stay with #69 thread.  Since strength isn't the issue, I'll stay with what is recommended.
