Hi guys, I just picked up a vintage tenon saw from a yard sale. I then restored and tested it. The saw curve seems to be off to the left side in its free run ( free run: only push with slightest force). I tried to troubleshoot this problem and found out the saw plate is warped to the right side in its lower part. Clamping the saw plate and bend it to the opposite direction is tried and not working. Any suggestion on such problem? Thanks
Yes putting a small piece of wood behind the bend then place it in your vise and carefully apply pressure until it evens out.
I’ve done this once or twice and it worked for me.
Before you start inflicting any serious (and irreversible) physio on your saw, please consider that saw plate tension is often a function of the position of the spine.
Adjusting this can often solve small bends in the plate’s edge.
Paul Sellers made a short film about it – there are other films of varying complexity also available:
I had a go at straightening the blade on my dad’s tenon saw, using the methods Paul showed here. I did get the blade to move and change, but my experience with banging the back of the saw on the bench was that it is quite difficult to get the impact right. You need to hit it as straight and flat as possible. I had a lot more success with the method shown in this video.
If the saw has a twist, Mark shows how to get that out in this video
