I may have some checkering work for him.
Prices for actuator? and control levers?
Anyone had this done?

Woody- I have not received any mail from you; not sure what might be wrong.

I was hoping for about $100 each, sell for $200, but cost came in at about $300. Only way the cost could be reduced is make a few thousand of them, or get the original fixtures.

The expensive part is the cocking knob. Milling out the rest of the actuator is a piece of cake, but to take a billed, and mill it sufficently to put the actuator in a lathe, and turn the cocking knob, then mill out the slot, etc, get expensive. Not just the machine time, the tooling cost to make up the six to eight fixtures required.
Special fixtures must be made up to hold the part both in the mill, and in the lathe. That is why the original tooling is important.
Investment cast is a no go, due to the cocking knob, I doubt it would last would last 500 rounds. (I am intimately familiar with investment casting)
I would use 41XX series steel, and have it properly heat treated.
The idea of my project was to produce an actuator that would be indistinguishable from an original Colt (or whoever made the original '28 actuators), not just make an actuator.
Just making a machined actuator would be cheap, make it two piece, and weld the cocking knob onto the body, but that would be distinguishable from an original.
