With its outside diameter being only 93mm, when bored to suit a 90mm piston you're only going to have about 1.5mm of liner wall left, What I know about liners you could fit on a postage stamp hence why I started this thread but I'd have expected to need more than that, you live and learn.
I'd have to run some measurements on a linered barrel to confirm whether it is possible...I'll do it when I get home after my impending trip...Ian[/quote]Have you changed your mind about coming to Normandy?
