You guys running modern forks with drum brakes - Where do you mount the brake stay?

I'm thinking of machining a spacer and using a long bolt into the upper caliper tab on the L side.

Of course I know I'm overthinking this but I would like to know what others are doing.

I made a stay out of 1/8" x 3/4" Titanium and just ran it from the drum to one of the caliper mounting holes. Did require a small spacer at the mounting hole.
I'm running CB550/4 forks with a Suz T500 drum.

robert-

yeah, but you can do this without titanium. i think jb's even lightened his toothbrush.

best. tt

 

[jbranson]

Tim,
It makes a difference...I use an electric tooth brush...so when you drill it to lighten it, it vibrates faster and the batteries last longer.
I'll race you to the molars baby!

JohnnyB-

you're on. my brush is heavy and slow and i don't get as much paste time as i'd like, but i'm quick in the incisors.

rotten choppers-

Sheesh - Titanium!

I don't even have any tools that will cut that stuff. I know from experience it's a b*tch to work. Somebody once gave me some ti mesh - i soon realized why it was free when I tried to do something with it.

 

[jbranson]

Yeah it's a pain to drill...the stuff work hardens so quick that if you stop drilling you have to break through a little layer of hardened Ti to finish the holes....makes lots of bad cruchy sounds when you drill it. If I remember my rules correctly...Ti likes a high feed rate...low feet per minute....on a drill that means low rpm, relatively high pressure.

It's a blast to grind though....lights up the whole shop. I only use it for the occasional brake stay or bracket that I want light, but stronger than aluminum. But..once you get the part made....they rarely break, never rust, never corrode and you can use a propane torch to get them to turn neato trick colors.

Yeah, we eventually used the mesh for a bbq grill surface. Cut it with an air cutoff wheel.

Thanks for the tip.

jb-

one word....

period material.

[jbranson]

Ti was used on GP bikes in the early 60's...perfectly legal in USCRA GP classes.
