I bought this Tyzack saw and am restoring it. The problem I’m having is that the hole in the saw blade where the nut goes has rotted (see the picture) a little which gives the handle some room to move which makes the handle wiggle a bit. Does anybody have a solution to fix this? Any suggestions of what I should try?

A traditional fix I have seen in a different hobby of mine was to plug the hole with a more malleable metal, peen it over, file it flush and then drill a new hole.
However, the item wasn’t as thin as a saw plate. It may still be worth a try.10 April 2014 at 6:09 pm #55336
Thank you @michaelp what kind of malleable metal do you suggest? Never done any metal work, so this is all new to me. Any additional guidance or links would be greatly appreciated.10 April 2014 at 7:12 pm #55369CraigParticipant
I haven’t done this, but, I might approach it this way.
Buy a small piece of steel or brass shim stock (auto parts store)and cut out a small patch to bridge the hole all around by 1/2″ or so. The shim should be thin enough so that when glued over the hole the blade will still fit into the handle slot, say 0.10 to 0.20″. Test the fit of the combined thickness in the handle slot. Roughen both the blade and shim and clean with Acetone, then glue the shim over the hole and clamp tightly. Wipe the squeeze out from both sides and let cure. Flip the blade over, center punch over a firm (not wood) surface and drill a new hole.
Hope this helps.
PS It might be easier to pre drill the shim stock before glue up and clamp the shim stock firmly to avoid lots of excitement.

Might want to consider drilling hole up to a standard washer size. You will have to take care to maintain center. Drill the I.D. of the washer to match the split screw and maybe grind the washer down a bit to match plate thickness.11 April 2014 at 11:37 am #56031Michael PetreParticipant
I’ve seen it done with lead, copper and brass so far.11 April 2014 at 8:55 pm #56052
I found a piece of metal that came off my Aldi chisel. It was 0.010 thick. I flattened and then superglued to the saw. I then punched a whole and then started out using a small drill bit and work my way up to the correct size.
Going to test it in a little while.11 April 2014 at 9:11 pm #56056
@craig @michaelp as you can see I’ve tried your suggestions out. It was tighter, but not 100%, I then realized that there is still a little gap between the bolt and the saw and also between the handle and the brass back as shown in the picture(Tyzack on left and Groves on the right). I’m going to make a bigger plate and cover both wholes and move the saw handle forward so that there isn’t a gap between the brass back and the handle (Just like the Groves).
If anybody has some insight or other suggestions, I’m open to them.
