Thanks Bruce,
I certainly would like to have some rebored blocks with pistons to match.
I have always felt uncomfortable ditching a scored block.
I will put these aside for now then.
tiger I forgot to mention the rings are available at outdoor king, search victa rings and they will pop up.
We are working on similar machines at the moment, I have this one ready to assemble after lunch.
