I have used 7/8 .095 tube for 3/4in hiem trailing arms. This tube and wall thickness comes out real close to the right size hole you need for 3/4 fine thread. I think I used a 11/16 bit just to clean the weld burrs out of the tube. These were wishbone style and made out of mild steel tube, not sure if this would be strong enough for a 3-link or swing arm. You might want to use chromemoly / DOM tubing. Also good luck if you are planning on doing this by hand in a vise! We use a lathe and it seems to work pretty well.

posted October 16, 2002 09:00 PM I have made both 5/8 and 3/4 rods for panhard and tie rods. I have allways used the tube that is ment for it...i think lefthander sells it. I got the taps at a boeing surplus( real cheap $5.00 for a lh and rh tap) then i start em in the lathe and finish by hand. Its not to bad if you only are making 2 or so but if making more it get tuff on the hands.

I have made my own trailing arms and panhard bars and just used tubing and welded the proper nuts on each end to fit the rod ends... It worked fine (I keep becoming a "store-Bought" racer as I get older and busier).
