Gearbox

Visited a swap meet today. My intention was to buy a Sturmey Archer 3-speed gearbox. For some reason I bought one Albion 3-speed and three Albion 2-speed gearboxes.

I maybe could use the 3-speed for the Baby Nut but why did I buy the 2-speed gearboxes. And I do not think I can get one working 2-speed out of the three of them.

End mills

Finally got the end mills I ordered all the way from China. Sold as Solid Carbide HRC60 and as such they should have no problem milling stainless steel stems, or...

Valves

According to an old James Catalogue, the valve dimensions are as follows.

According to my measurements the valves are somewhat longer.

Anyway I'm not patient enough to wait and see if any JAP valves will pup up so I scanned through some valve makers catalogues and found out that Manley GEN II exhaust valves are pretty close.

Found a set of eight valves for sale on eBay. These were custom made and the valve head was close enough to fit without modifications.

Valve head = 1.6" & Valve stem 7mm

Of course they will have to be shortened and modified with slotted stem ends.

The main concern is if they are too heavy compared to the original ones.

In case they can't be used I'll buy some used NASCAR titanium valves and try to modify them instead ...
