Hi Puffs.
Well you know how it is ,seen alot of barrels for sale on ebay, but as soon as you want one. My plan is get hold of a nice one and get it rebore, correctly. Interesting what you say about
piston sizes though. My piston is a 69.5mm with a 3 thou gap ( seems like the go to size for rebore engineers)which is 0.0762mm. The gap should be 0.05mm. So I need a piston at
69.5262mm to save me reboring. The search starts for a 69.53mm piston or a barrel. Not gonna pay £185 plus £10 p+p though.

The shop I went to said they dial the rebore to 2 thou. Which is more than I wanted - but I let the engineer do the size he saw fit, and with my own calculations (2 thou is 0.0508, I didn't think it was unreasonable.
