Hello,
can anyone advise me on a method to fasten threaded ends into a carbon pushrod?
Are they epoxied and screwed (the threaded ends) into the tube?

thanks in advance

The carbon tubes I buy, are a slip fit for 2/56 rod. Just rough up the rod, and glue it in with Epoxy or JB Weld up to the threads.

www.darrolcady.com for the pushrods.

He also has rods that are a slip fit for 4/40 rod if you like that.

Epoxy works wonders.

As daven mentions, there are CF tubes and pushrods available. Both area LHSs have them here. I like to use heatshrink tubing to speed up making them. It also makes the joints bulletproof.

I scuff the metal rod after cutting it to length. Slide the piece of heatshrink on the CF rod out of the way. Wipe epoxy on the part of the rod that's going into the tube and slide it in. Slide the heatshrink over the joint. Apply heat at one end and then shrink the length of the heatshrink.

The shrinking tubing will actually squeeze the excess epoxy into the joint. And more excess will come out the ends if there is any. And it bonds the heatshrink over both parts. Reinforces the joint. Makes it look neat too.

You wind up with a pushrod with perfect length and bulletproof joints. And a clean installation.

I always use the method outlined by www.darrolcady.com I've made them for pylyon racers up to 35% using the same methods outlined there. Never had even a hint of a failure.
