Graham,

1961 CB72-10832 the frame has been severely modified for flat track racing.
1961 CB72-11370 most likely to restore. Hanging in the shed. Bit cluttered.
Engine CB72E-110865

Have been picking up a few bits as we go, but won't be anywhere near like your rebuild.

A couple of swing arms with the ID plates and a very early swing arm with the passenger foot peg attachment.

Early aluminium brake stay, longer than normal but I don't have an early brake plate. Looks like they went to standard brake stay and brake plate, but with early actuator arms fairly quickly in production. Early forks somewhere.

Richard

Thanks. All interesting stuff. What are the mods on the flat track frame?

I have a 'short' alloy brake stay if that would help you......

The first batch of my NOS double-butted front spokes arrived today. Let's hope the rest are as nice.

Tracking down a full set of front spokes was a little harder than I anticipated. I bought 3/4 of a set from US ebay sellers and there were fine. Th eset I ordered from David Silver turned out to be single butted rears rather than the double butted fronts I was expecting.




I managed to track down another set in teh US so will have to wait a week or so to get those.

With wheel building parked for the moment and the weather improving. I turned my attention to the tinware that I had been procrastinating over for some time.

I picked up a pair of rather rusty but apparently unused side panels some months back. These were treated to a dunk in an oxalic acid bath to remove the rust followed by a trip to teh bead blast cabinet. The badly pitted toolbox and fresh headlight were treated to a similar process and then all four parts got a coad of acid-etch primer.



As usual - as soon as the primer goes on you can easily see the blemishes in the parts. A ding in one of the sidepanels was tapped out with hammer & dolly and some pits in the other parts were filled with 'knifing putty' (a kind of very thick primer applied with a knife).

The two fenders had been sitting in my workshop for ages unfinished. So I gave them a rub down and added them to the to-do list.



The early rear fender is much lighter than the later ones and has its wiring channel in the middle underneath.




After a bit of filling, wet sanding and priming I ended up with a selection of pretty tidy pieces.



All done just in time for the weather to change and for the rain to set in....
