Hey guys… I have a Disston 8 pt. that I have sharpened with the progressive technique. Unlike my other saws, it starts out very smooth, then about half way through the forward stroke it has a spot where it starts to stick, or there is a sharp increase in the resistance in the stroke.
I have jointed it again, and re-sharpened it. There was maybe some improvement, but not much. I’m wondering if this is an issue with the set… I have looked at it and it seems to be fairly consistent, but now I’m questioning how much of a variance in the set could cause something like that? Would I want to increase or decrease the set in this situation?
Or could there be some other problem I have not considered? Any help is appreciated. Thanks guys!

I’ve been restoring some of my Granddad’s old tools (very slowly thanks to too many life things getting in the way) and had a similar issue with his brass backed tenon of 14PPI. I’ve managed to smooth the cutting action (mostly) by reducing the set of the teeth where it seemed to snag using Paul’s two-hammers method. The initial set seemed far too much, despite using a ‘fine’ saw-set at it’s finest setting (supposedly for teeth up to 24PPI).
Now, I’m pretty much as new as can be to this tool-restoration stuff but another thing I noticed while I’ve been working on his panel saw is that over the years (and with deteriorating eye-sight I’m sure) the depth of some teeth were way off that of others. I’ve had to completely remove the teeth from the panel saw and I don’t doubt that teeth of an uneven depth will also cause a stopping motion, so maybe check that?
Anyway, I now have to figure out how to cut new teeth when I’ve only got a Black and Decker workmate to use as a table/clamp, and the saw won’t fit in…
Good luck with your saw!
I know it’s been a while since I posted this but I had to pick up some new saw files and it took me a while to get back to fixing these saws.
In case anyone else is reading this at some point and has a similar issue, I was able to fix it by increasing the rake on my teeth a bit (increasing meaning leaning the front of the tooth back a few degrees). The Disston and my backsaw are both nice and smooth now.
