Hi all
I bought a new saw to restore, and when I got it I realised it needed new teeth so I filed the old ones away. Now it turns out that after all the filing (maybe it might have been like this even before I’m not sure) that the plate isn’t entirely straight along the edge but theres a slight convex curve along its length.
Is this something I can leave or should I keep filing to make it straight?
Yes the slightly convex curve on the sawplate is called “breasting” on a handsaw. It is supposed to have some effect on the mechanics of sawing but I’m not sure that I understand it fully. If you have a look at the British handsaw manufacturer Thomas Flinn and Co under their PAX Hand Saws range you will see the term “breasting” listed as a feature of the Pax handsaw type. It keeps “fewer teeth in contact with the wood and thereby minimizes friction”. See the webpage:

I hope that that pasted link works.
Cheers

Saw Manufacturers usually only put this on there top range of hand saws.
I have a Spear & Jackson 26″ rip 6 tpi and a Sandvik 26″ x cut 8tpi both breasted.
Lost count how many saws I have must be around 25-30 Mark- This reply was modified 8 years, 3 months ago by Mark Armstrong.
