That's a good price considering what a genuine TD/TZ costs. They have been bid up to crazy prices. It's so far outside my price range that  I don't even look any more though..

If I had something it made sense for im sure id rationalize the shit out of it and put it on a card, but the only bike im doing for myself at the moment doesnt have a front end wide enough to fit it. And im not cutting into a 2k hub! Maybe when i get to the sohc 750 sitting in the corner ill design one...

Question for whomever. Drum brake arms, you think it's possible to make a universal set for each brand? I have 3 different honda ones (160mm, 180mm, 200mm) and thought I'd play with them all at the same time to see if there's a way to do it. If there is, I can cnc a lot of these things for cheap, both the male and female parts.

You'll likely need broaches for the female splined parts. They could be cut on an EDM easily enough, though. Single point broaching them in a cnc would be rather time consuming, or cutting them. You'd have to run something like a .030 end mill.

I have a couple rotary broaches to do brake and shift tabs for rear sets. Those things are awesome.

Slater, and Polygon Solutions have quick turn arounds for roto broaches.

The only thing that stopped me making alloy operating arms for the CB 350/360 (plus CB77 and CB450 hubs) TLS brakes I have was broaching the splines. Both need 'new' arms because the chrome is bad. Link rods in stainless steel are the easy bit
The CB77 are a nice shape so worth getting re-plated sometime

This is what you need for the splines.

I've looked at rotary broaches many times for doing brake arms and shift levers, such cool tools. It's hard to justify the cost for a hand full of parts though.

Last one I bought from Polygon was $600, add another $300-$400 if you don't have a holder, and $150 for them to reverse engineer it.

I was buying brake and shift levers, and welding a tab to them for the last several years. Topped $15K in levers last year, so broaches were bought.
