Chainsaw Repair

There must be a thousand ways to skin the same cat .Whatever works, works .

I have a Monarch 10" EE lathe with Cushman chucks . A 6",4 jaw, face plate and an 8" with long reversible jaws .Plus several  more I haven't had the time to modify to take a D1 3 mount .

What works for me is clamping right near the ring groove using brass  shim stock to soften the jaw bite so as not to mar the piston .I've even used the aluminum from a beverage can . With that you have to be very careful not to ding the part .Once again though methods mean very little ,results are where it's at .
