Sometimes I have too much fun!
Some time ago I decided to make some Profile splined hubs.
The hubs turned out just so-so ... the fit between the
splines on the axle and the splines in the crank is touchy
and hard to control. I've given up on making Profile splines
for now but I'm still tinkering with other ideas.
During my "Profile Phase" I made a titanium axle with
Profile splines. I don't have much experience machining
titanium and the splines didn't turn out well. This axle sat
on the shelf until last weekend when I was making an axle
with square tapers and decided to try re-machining the ti
axle to a square taper.
The machining went pretty well so I decided to make a whole
hub - axle and hub shell. As usual, I photographed the
various machining steps and put them in 'this gallery'
(unicyclist.comTiOpen ↗)
I'm not done with the hub. I still have to drill the
shell for the spokes, make a key for the keyway and
assemble it. The remnants of the Profile splines are kind
of weird and that's where the bearings will be. I'm not
sure if I'll press a 40mm o.d. x .750" i.d. bearing on
the splines or turn the splined area down to 17mm for a
40mm x 17mm bearing.
Also, I'm not exactly sure what I'll do with this hub after
it's done but I have an idea ... stay tuned!
