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?

| 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.
http://www.smallparts.com/
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.

| 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? |

| 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.
