I am going to get the casings line bored. Dragon wont do it, unless they take on the whole build, is there anything i need to know to tell the engineer when i find one to do it

The engineer will need to know the clearance between the crank and the bush. The figure is quoted in Waller, it seems a bit “baggy” but that’s to allow for expansion.
