Ok Bryan.
Once the frame has been alignment checked (I've put the bare engine cases back into the frame to enable that to be checked properly) I'll be taking the cases for vapour blasting. Once back I will send the barrel up to you for the rebore but I won't buy the piston until you have measured it. The s/h barrel is rusty and I have no idea what the existing bore size is as it didn't come with the piston.
Just come back indoors to make a brew before venturing out to make more missing brackets!
