Default Pedal Bush Redesign
Hi
I am currently building my pedal box and have a bit of spare time and a new (to me) lathe to play with.
Im thinking of producing a 2 piece top hat bushing instead of the straight through design in the book. Im thinking I will probably reduce the steel tube length by about 6mm and have a 3mm flange on each end of the bushing with the same outer diameter as the tube.

Any thoughts on this? i know its probably overkill but like i said i have the time and a lathe waiting to be used.

I was also looking at the oilite bushings but have told not to bother using them when using a threaded pivot.

Cheers
Andy

Andy,

I changed the design of mine slightly. I used a nylon insert with a stainless steel crush tube. Very similar to the wishbone idea. Works a treat and the pedals operate really smoothly now.

Cheers

Dave

Did you do them like a top hat or straight through with a crush tube?

oh yea top hats are the way
bought an 18 inch piece of acetal off the bayŁ7 and TJ turned them down on our lathe ....simples
oh and we didn,t shorten the tubes we just moved each support out by 3 mm wanted to keep the tube lenght for balance and increased bearing area
cheers les g.
we did post pictures for them on here

If someone had far too much time what would be the perfect money no object method of pivoting the pedals?
Would it involve roller bearings?
