Tom or anyone else got pictures of .750 thick spring gear being
formed? How big a press machine and dies we talking about here?
What type of machine shop would have this equipment? And how long would
it take them to set it up just to bend one gear leg.?

Anyone still looking for material for 601XL main gear might do well
to contact the following. We do a lot of business with these guys, so I
don't know what sort of discount is afforded us. One-Time orders
shouldn't be too much more. Both companies are in Portland, Oregon.
Reliance Metals (800-759-5990): .750 X 7.75 X 97.000 6061-T6 (cut from
plate) $308.00
Copper and Brass Sales (800-926-2600): .750 X 8.000 X 144.000 6061-T6
Barstock $235

Monty,
It would take about a 100 ton press, but more importantly, it would require
the proper top and bottom dies to maintain the necessary radius to prevent
cracking of the material.

We have a 140 ton brake here, but I opted to use our old 35 ton machine because it lent itself more to the modified dies I made. You're right, you do need the correct dies, but there is no sense in spending $3500 to buy them. I MacGyver'ed a nice punch and die using a laser cut profile welded together and buffed smooth.
We definitely don't want to 'coin' the 6061 gear legs, which would require the 100 tons mentioned below. Using an overly large die and the correct radius punch, the angles noted on the plans can be achieved using less than 35 tons. That's the easy part.
The more difficult aspect of bending your own gear is getting the bends square to the machine. No, REALLY square. You'll be using an awful lot of shims when you add the wheels to set the correct camber and toe-in/out if you're not careful at the brake.
Providing one is carefull with the alignment, uses the correct radius punch and correct size die, and takes their time, the gear could easily be formed in your garage using a manual hydraulic jack. The quality of the bend would be a direct reflection of the quality of the framework made to hold the jack and dies. Purchase a small piece of 3/4" extrusion to test your setup before taking the plunge and losing a lot of $.
