Question for trackbird
Question for trackbird I have a set of BMR adjustable lca's and phr, with the poly ends. I have since read (great site btw!) that rod ends are better.
My question: would it be feasible to use delrin bushings instead of rod ends on the arms I already have?
If I was to fab my own what size tubing, and rod end size, would you recommend?
Thanks for your time,
Brent

Delrin will not allow proper rotation of the rear axle. This will cause a binding problem, just like poly (very similar to poly?). So, it is different, but it will still not fix your problem. A delrin/rod end combo might be a decent choice. However, due to the arc of the PHB, there will always need to be a slight amount of give in the "solid" end of the poly or delrin/heim combo. That would require some experimentation to see if it is going to function properly. However, delrin is hard enough that I don't think you'd see any real reduction in noise levels so I'd probably just use heim joints. As for rod ends, I'd use a 3/4" heim joint (QA1 XMR-12 and XML-12, right and left hand threaded rod ends) work well. They are about $30 each. You will still need spacers and some type of tubing. The size and shape of the tubing required will change depending on what you build them out of. Aluminum, steel, etc. So, I'd check with the tubing supplier for strength characteristics of the material you intend to use, then consider the potential for applied load and go from there.
Hope that helps!

Its a different part for a different car but there once was a rubber or poly bushing there.
Look at the end opposite the ball joint... It is really just a really big bushing like the one in a heim end...
Stick that in one end of the arm and use a poly in the other... For an all out track car go spherical in both ends. There is a bushing out there that will press in the arms you have now... Alot of times people also the groove the arm for retaining cir-clips.
Don't go solid in the other end like here... On this arm that is a shock mount... I don't know why he likes to wail on shocks...

Delrin is very similar in appearance to nylon, but is a much superior material. Delrin is actually a trade name; it's real name is acetron. It is very machinable as well; cuts about like aluminum on a lathe. To buy it in bar stock, the price is comparable to 6061 aluminum, and can be used in place of aluminum in many applications. This is not cheap plastic.
BTW, I second the vote for 3/4 inch QA1 rod ends; these are very nice! They even have a teflon wipper that helps keep dirt out. They are well worth what they cost. Check out Colman Racing for the aluminum tube, and I can make you the aluminum spacers that you will need.
