To start with I have never made a saw from the very beginning and I have limited knowledge on sharpening. I have attended two sessions with The Traditional Tool Group saw sharpening and the second time around it does become a little better in remembering what to do. But saw sharpening is not what this thread is about.
Just before I get to my questions I think some background is necessary. In the Announcement sub-forum there is a saw maker that purchased too much of a certain thickness of saw blade. Take a look here for those that have not seen the post, https://www.woodworkforums.com/f12/quick-usa-plate-pre-toothed-available-limited-time-183511
So after looking at this thread I am thinking that I can make myself two tenon saws. One used for rip cuts and the other for cross cuts. Based on this information here are my questions.
What would be the best thickness for tenon saws?
How many saw nuts would normally be used in tenon saws?
Can the saw nuts be source locally?
