Rim

Built up the front wheel using a set of stainless spokes, nickel-plated brass nipples and a stainless rim in the same pattern as the original Dunlop rim.

I haven't built a wheelbuilding stand yet and someone (!) had borrowed my welder yet again and was late returning it so I was unable to knock one together, so I trued up the rim in place between the front forks. This helped get the wheel centred without having to measure offset - I just had to make sure it was centred between the stanchions. Finished up using a dial gauge, and was surprised at the amount of out-of-round caused by the welded join in the rim.

Nuts, part II

Found a little time today to make up the metric-thread sleeve nuts for the repro speedo; turned out pretty good, I think.

Nuts

Fitted the pushrods and rockerboxes. Bought a US model chainguard without the rear plate and fitted that. Engine plates are off again temporarily while I sort out a problem with one of the studs in the swingarm mount.

A while back I bought a repro speedo because the plan is to go for the '68 TR6C look with a single speedo offset to the right. This style of bracket requires special sleeve nuts and spacers in order to mate with the mounting studs on the bottom of the clock, so I picked up the necessary fasteners. All was looking good until I tried mounting the clock and discovered that the studs on the repro clock have a metric thread! The sleeve nuts are of course an Imperial thread (don't know if it's CEI or UNF. I may have to fire up the lathe and make up some bespoke nuts.
