One thing for sure, MAKE SURE THEY MASK THE INNER FACE OF THE DRUM, AND THE SPROCKET TEETH!!!


My painter didnt mask the sprocket teath. Luckily, he must have painted it with the drum side flat down, since there was no paint on the teeth that side. I had to mask the other side and use a wire wheel to strip the paint off. :twisted:

Thanks. I'm taking notes. I'm going to go through all the bags again. If I miss something small I'll blast and paint myself.

I found a source here in the East for cadmium plating nuts and bolts, head steady plates, etc. Hutchinsons Cycle on the north shore of Boston. I spoke with Don Hutchinson today. They will plate as much as I send him for $200.00. He had a great suggestion- put the nuts and bolts for each assembly on a photocopier and copy them. Then when they come back place the finished parts on the copy to match them up again. I'm going to go with the old non-shiny plating. I'll report back when they are done.

I didn't know Don was doing Cad plating, I've always used Burbank and had excellent results. Not so much as one tiny washer missing from 15 to 55 pound batches.

I think he sends it out. I'll post my thoughts when they come back. I very much enjoyed talking with him.

Spent time today degreasing the engine, gearbox and various frame parts in preparation for blasting. I used a towel and contact cleaner for degreasing the engine plates. When it was time to degrease the swing arm I decided (a word which connotes thoughtful deliberation) to warm the caked-on grease with a propane torch so it would scrape off easier. Problem is I put the swingarm on the towel full of contact cleaner and then applied the torch. My wife and daughter had a good laugh watching me trying to put it out. Luckily the garage was open and I was working near the door so I could throw it on the gravel to burn out. Never too old to screw up.

Found this fairly well preserved paper sticker on top,of the rear isolastic tube with the frame number on it. I think I will try to reproduce it and put it on after painting.

Wrong picture:

Here is the gearbox stamp and engine stamp:

There is a "G" stamped to the right on the gearbox just on the edge of the picture. Any idea what this means?

I have never seen one of those paper stickers on the 40+ Commandos I've had my hands on...

It slid right off with a squirt of contact cleaner. I may just adhere it back on in the same place after painting. I'll post measurements at some point.

Gearboxes occasionally have that additional letter stamp, not necessarily 'G'. They were factory codes, the meanings of which were generally unknown outside the factory, so can be ignored.

I have seen 'factory' pictures showing those engine number stickers on the top of the timing cover, usually placed over the crankcase joint.
It seems they were removed at some point before the bike was sold.
I have no idea how it ended up on the cradle.

It didn't appear glued on. Maybe it just ended up there and didn't fly off. There was a fair amount of oil and grease on the tube.

I finally found a few extra minutes to work on the bike. I removed the tires - Avon GP front and Dunlop Roadmaster TT100 rear. They couldn't be original since the bike has 12k miles and they had good tread. I did get the license plate and current title for the bike though - 1975 title and last stickered in 1980. I really like the plate but it won't work in MA.
