I saw a video a while back (maybe here?) about tumbling aluminium engine parts. The result was fantastic, the process closed up the pores in the aluminium and created a superb surface, real smooth. Don´t remember what media was used, probably quite important.
Now I’m very concerned.
Are pinion shafts repairable?
Ceramic balls I believe.
I also believe it’s the process that cNw uses on cast parts. It gives a really nice finish that’s SO easy to keep nice.
I use this guy in the U.K. (trident sam put me on to him) and he does a great service...

Yes you will have to make a decision on whether to repaint them in silver or not. The Norton factory used one helluva tough silver paint on the cases.An option on the cases are to scrub them up real good and paint them.
Norton painted them originally.
Focus on detailing the Head and barrel.
Where are you Norcoastal? I highly recommend Cape Cod Dustless Blasting (website online). I had the pleasure of being able to use the equipment to try it out on a gear case. Amazing results in stupid fast time. I had my head, cases, gear case and inner cover done and couldn’t be happier.I’ve Googled “vapor blasting near me” and I can’t find anyone around me that does this. I may need to send them out somewhere.
