Restoring an Old Saw

[roxanne562001]

Looks like a fun project. Now I will have to hunt for an old saw at the flea market.

I have been looking for a decent long hand saw. All I find are the short ones. After watching this video, I may just rebuild mine. I really like it , it is just dull.
Thanks Stick.

use a feather file... pay attention here, size matters...
fit the file to the tooth count...
if the teeth are hardened on your saw... all bets are off - go get another saw...
hardened teeth tend to have a bluish discoloration different from the blade body...

sharpen in an alternating left-right pattern,,, sharpen every other tooth from one side of the blade, flip the saw around and have at the the remaining teeth... Push, not drag, the file across each individual tooth 3 or 4 times, (more times to sharpen brutalized teeth)...
All done???
not yet....
back (micro) bevel the tip of every tooth to avoid having them break off during use....

I got essentially the same file, or maybe the exact same file, from Lee Valley: https://www.leevalley.com/en-us/shop/to ... edge-files I couldn't get my Shark Saw quite as sharp as the original grind but I did make a major improvement in it. The teeth are small so you need good light and to clamp it in a vise so that just about all that is showing are the teeth. The edges of the file are brittle and fragile. I managed to chip out a couple of small spots getting it bound up in between teeth and sticking a bit. I haven't used it much but I'm sure there is a learning curve with getting a straight stroke and the right amount of down pressure. You probably need to take a marker and mark the teeth for every other one before you start as it's almost impossible to keep track otherwise. Those are small teeth and hard to see at our ages.

wrong size file????
should be no binding...

It was probably from me not stroking straight through and putting an arc in the stroke. Maybe bearing down too hard too. It was the pistol grip Shark Saw with only one cutting edge which should be about 14 tpi so it should be the right file for that. I'm not sure if it would fit between the finer teeth on the finish side of a Ryoba.
