Push/Pull pull rods

Gino Iorfida · Post by **Gino Iorfida** » 14 Apr 2003 4:44 am

Ok, 2 questions:
1) Where could one find extra pull rods for a push pull (please dont say welding shop, don't have any accessable)? What diameter are they? 1/8" or the 7/64" that I've seen mentioned

2) Supposing I find pull rods, and I want to use them for raises, how is the end flattened for the hole to be drilled for the connecting wire from the pull rod to the changer finger?

I get mine at the welding shop - 1/8

Buy steel rods for the pushes and aluminum rods for the pulls. Just use a hammer to flatten the end and drill the hole.

You can get mild steel 1/8" rod at Lowe's. It's soft enough to flatten with a hammer and easily drilled...

Small Parts Inc. in Miami sells 1/8" stainless steel rods.

Either use a hammer or a large vise to flatten one end. Then drill the hole in it. Use a larger drill bit to very slightly countersink the hole on both sides. This will allow the "hook" to move more freely.

Aluminum is ok but has a higher expansion and contraction coeficient than stainless steel. While rods expanding and contracting have little to no affect on P/P's*, I recommend the stainless steel ones if you can get them.

Good luck,

carl

* NOTE: The reason expansion and contraction (of pull rods) has no affect on a P/P's is because the main stops are at the changer ("half-stops" excepted); rather than at the crossbar crank like used on "All-pull's".

Gino, I can send you as many full length rods as you need and you can cut them off to the lengths you need.

Should I get the 303 or the 316 stainless rod? does it matter?

What about bell cranks. I placed an order for some pull rods and bell cranks with one person, but it doesn't seem to be happening. Anybody sell P/P bell cranks?

Bobbe just put up on his site that he's selling the new bellcranks.

The 303 should be slightly cheaper than the 316 and is an alloy that's made more for machining than 304 which is more for welding, which is another common alloy.

Yes get the 303. 316 is difficult to machine. And for pull (or push) rods, the 303's are more than adaquate.
