I have a number 3 that I picked up at a fleamarket years ago. In the great cleanup effort that is focused upon the tools I've brought back from Mum's I thought I'd give my little #3 (my favorite) the attention it deserves. Imagine my horror when I took off the front knob and found the original "studdy" thing that held the knob on had been replaced with a piece of 1/4-20.
I don't know what the threads are, nor the stock for that matter. The tote's stud is 20 tpi, but the profile is not the same as 1/4-20, and the dia is only ~.209, while 1/4-20 is about .244.
Suggestions anyone? The only thing I can figure is to drill and tap oversize.
Happy Thanksgiving, all.
