Got the muff casting from the foundry this week so I thought I'd better do a bit.
Set the crankcases up on the CNC mill by sandwiching them between two angle plates. Had to use the CNC in manual mode as they were just a tad to high to fit on the Bridgy.
Faced the top to clean up as I had to plug the existing barrel stud holes and also weld a 3/8" thick piece of alloy onto the cases to take the side studs. I then bored the mouth out to take the Liberty barrel.
Next two shots show the machined muff fitted to the crankcase and the last shot shows the whole lot assembled.
