1961 CB72 Project

Do your eary coils have the PUNCH dot in the metal case at the edge near the terminals?
If you don't locate the front mount bolt I'll check here. ..................lm

The bike is now resting in its build-up place in the shed and I spent a little time looking for the elusive top front engine bolt. Early ones are M8 x 135 compared with the later M10 x 135. I looked everywhere including some places it couldn't possibly be. It just wouldn't reveal itself.

Today was earmarked as the 'wheels day' but I found the coil brackets and got my freshly-painted coils in place just for a little assembly time, as I admired that lovely engine sitting in its chassis once again.

Out came the previously-polished hubs and brake plates from their hiding-place. I don't want these to be too shiny - I am just trying to get back to something like they would look like back in 1961.

In any case the rear hub still looked a little unloved so I gave it a quick turn on the polishing wheel. Trying to get a super finish on theses castings can be a little depressing as there are tiny pockets throughout the metal and you just expose more as you sand or polish out the surface ones.
I searched through all the spokes that had been re-plated but they didn't inspire me with confidence. Although I'd spent some time cleaning them up they just didn't look like they were going to look right or perform the task of keeping the rider safe.


After a considerable amount of indecision I came to the conclusion that I would have to get some new ones. Luckily, Central Wheel Components near Birmingham will manufacture spokes to a set of measurements. The decision is now between zinc and stainless steel. I don't really want something that looks too modern so I am going to opt for stainless-steel to the original measurements. Fronts will be double butted (bigger at teh ends than the middle) while rears will be single butted.

Yes, they both have. What is the significance of that little mark?

I'll try another couple of places for the bolt and I'll let you know if I cannot find it. Thankyou for the kind offer.

That is a INDEX mark which is to line up to the crack where the coil mount comes together. ...............lm

Graham, Central done my wheels with stainless, but they don't do the gold colour ends, had to take them away and get the ends done else where, and i sent them back to central to finish.

Alan

Thanks for the info. I may have to get the nipples re-plated but I'll build the wheels up myself. Did you get the double butted fronts and single butted rears in unpolished stainless?

Any pictures?
