Im having a mental block here....

I have made some aluminimum cam/rocker type things for my pushrod gear change system.


I want to weld some brackets onto my chassis and then use a bolt to hold the alloy rocker inplace?

I could just allow the alloy to pivot on the bolt, but its not very durable and about as proffesional as the brittish government...

So what is the correct/suitable method for pivoting an alloy part? I Guess ideally I would weld on some tubes and press bearings in, but I cant weld alloy....

Pics appreciated

correct way to swivle?


teee heee

how about a steel or fozzie bronze insert

Or just machine out two recess and push in a pair of suitable size ball races if you realy want. Deoends how big the part is and how much force/movement its going take (stuggling to visualise it or the install)

One simple option could be a couple of rod ends. You can then bolt the swivels in place without any worry of them binding.

Press fit some brass tube into the ally rocker to act as a bush. Make sure it pivots on the plain shank part of the bolt and not the threaded part - might need to pack out with washers to space it properly.
