I have a few 14″ Tenon saws laying around that I need to restore and sharpen. I’ve done a long miter box saw recutting the teeth and sharpening before and it turned out well. I was thinking of recutting the teeth one of these tenon saws to be aggressive and fast for those larger in size tenons. Would 9 ppi rip be too aggressive filed the way Paul does them with the progressively raked teeth? I think the the “most aggressive” rip tenon I have is 11ppi, but it’s a lie neilsen thin plate that I’m sure is not filed at 0 degree rake like I want this one to be. Plus, I’m actually not incredibly fond of the thin plate for larger tenons as it seems to heat up the saw plate too much and cause the saw plate to bend here and there in the cut. I would go normal plate next time if I were to buy another for large tenons. Could I go 8 ppi or would that be too difficult to saw? Any opinions or thoughts?

I have one Tenon saw at 11tpi I think that is just about right.
When I file rip saw I come 3 or 4 degrees off 0 I just feel it makes cut a little smoother just my preference.
That’s the beauty of sharpening your own saws you can experiment a little to find what works best for yourself.21 October 2014 at 7:06 pm #119888Well my other issue is that I prefer a smaller tenon saw with a shorter cutting depth when I can use that. For example, I have a smaller saw that could double as a dovetail saw (although not as small) that I enjoy using, but it takes a little longer to cut tenons. I’d love to take a smaller saw like that and give it larger teeth to get through the tenons better. Some of the projects I’ve done lately have been 2″ or longer tenons by 3″-4″ wide and it would be nice to have a smaller saw that cuts faster, but it seems like they are premade to 13-15 tpi roughly.
23 October 2014 at 2:24 pm #120065I do not know how many saws you have.
I cannot see any reason why you can’t file smaller teeth off of saw and recut larger teeth on saw plate.
As long as you do not make your depth to small, for the tenons you have in mind.
Like I said dose not hurt to experiment with tooth size and geometry.
I have tenon saws with 11 to 16tpi.
If a tenon really large I use a panel saw just remember to saw from each side. -
