PROGRESS REPORT

The Covid-19 timing is terrible.
Because of the shutdown,Ive got a restored speedo from Russel at Chronometris and a box of parts on the way from AMOC and they're are both stuck in freight halls somewhere between Britain an Australia.
As you would expect the bits in freight are the parts I need to finish the hubs and cylinder head and almost anything else I want to work on.
Apparently the freight could be held up for another two months.
Bugger.
Here's a few pics of progress so far.The gearbox was in great condition just bearings and seals and kick start lever and quadrant and gearbox lever and shaft .
The kickstart is new, the gear lever is made out of an old kickstart that had a good spline.

The engine has new main and big end bearings, the barrell is sleeved back to standard.
Cams were machined by Newman cams, I'm looking forward to how they perform.
The drive and timing shafts are new as is the oil pump. That work cost a bundle but hopefully it means a good reliable runner.

At the moment I'm working on the tin-ware and frame, the only real damage was to the front mudgaurd which has been repaired, the rest is being blasted and ubdercoated ready for the first assembly.
Sorry about the sideways engine, I'm sure I will work out how to stop that by the time I get to my next post.

Looks great. What was the kickstart you used for the gear change?

Its was the original kick start off this gearbox, it has the same spline as the gearshift so i cut wedge at the spline end to and heated it to bend it back to a better angle and did the same at the other end.
The pedal part of the lever unscrews so I brazed that in and cut the shaft off flush and tapped it to take a steel bolt and brazed that in place that was the same size as the bearshift rubber
The lever was pretty heavy so the grinder took off a lot of weight before polishing and chrome.
It wasn't a big job and I get a nice steel chromed shift out of it.
