Good morning,
The guys on BritBike suggested I try this site with my question, so here goes.
I'm busy restoring a 1955 M21 which I received in a dismantled state and, as you all know, there are inevitably bits missing.
At this moment I am short of several wheel hub spacers. I could order these and wait several months for them to get through our hopelessly backlogged customs office, or I could turn them up on the lathe at work in 5 minutes flat.
If only I had the dimensions...
So, in the expectation that I'm not the first person to want to make these simple parts, I wonder if anyone happens to have the dimensions of the following for my 7" front hub and 7" rear crinkle (plunger) hub:
Firstly the simple tubular distance collar which fits under the nut on the right hand end of the front hub (65-5890), and
the two similarly shaped collared tubular distance pieces which sit either side of the right hand cover plate on the rear hub. (67-6066 and 67-6077).
I would probably be able to deduce the sizes by measuring the spaces in the assembled hubs, but would always have a question mark about whether I had allowed the correct clearances and so forth.
