Sounds like a great way to do it and I may just use (but I still like
re-inventing wheels !)
You'll be done sooner than I am, because I do not have the saw to cut
through cylinder barrels !
What I really like is that I learned :
(A) that there is a 'front' and a 'back' to the piston (didn't know that)
(B) the the 'piston mark' is not just for decoration (actually I thought it
was for weight balancing or something)
So, I learned a new, cool way to do it, and some other useful tidbits along
Can't wait to see what other answers there to questions I didn't even know
to ask !!!!
I Love VV !
