or replace the sleeve and go with a stock piston. Probably cost the same when you factor in the high prices that +060 pistons fetch. If you have an unlinered barrel you can fit a bigger piston for a little bit more oomph
On many occasions if a barrel finds it's way to us, it because it's horrible in some way. The nice jobs seldom come here.
So often a custom liner is required. Especially if it's discovered whilst boring out to removing an old one.
We hold centrifugally spun iron castings in a few common sizes, so if the machine is free we can knock up specials very fast.
On a side note I was called by westwood many years ago, and had to say "sorry but we don't have the capacity to make your liners"
