Tightening loose tenon saw handle

[gold_bantam]

Hi all,

I have a vintage 14” tenon saw which I really like. When I was given it a few years back I had to find a new third screw for the handle and ended up getting a nice split nut one in brass. I cleaned up the handle and finished it with coloured shellac. It generally works a treat but there is a very very slight wobble in the handle and I frequently have to tighten up this split nut. I had an idea to remove the shellac and treat the handle instead with lots of boiled linseed oil. Would this expand the wood enough to grip the saw plate better? I’m not in a position at the moment to make a new handle and probably couldn’t do it accurately enough with only hand tools given my experience level.

I've used paper as a shim sucessfully, would take finish quite well I expect so could be hidden.

Thank you Fitzroy. That actually sounds like a very fuss free option.
