Sure Dave, but with the proviso that I haven't tested it out yet. Seems like it should work but, what's that state motto? Show me.
Hard to give time estimate as I was making it up as I went along. But with material that is closer to finished dimensions than the stuff I used ( I tend to use up scrap material with this kind of project) it would only take about 30 min lathe time, and about 45 min or less on the mill.
So about an hour and a quarter machine time at the most. If one were a real machinist, under an hour.
The material cost? Well you'd use about 4" of 3/4" stainless rod for the pin, and about 2" of 1.25" brass or bronze rod for the bushing. Then two 1/8" roll pins. How much does that cost? Well the brass or bronze is the relatively spendy stuff but then again a machine shop will have some shorts lying around for a good price. Maybe 5 - 10 bucks for that. The stainless would be a couple of bucks.
I'm really spit balling the material cost. You really ought to be paying scrap value for the brass/bronze.
Hope this gives you an idea. I'm getting to be an old fogey, I think everything costs too much. But then when I make something, and it's all custom work, and if I actually cost out my time, then the price of things doesn't seem that bad.

I realize that some folks with lots of time and effort can develop talents, but remember, I'm the guy who once twisted off the bolt that held the waterpump housing onto the engine of a 1966 Ford Falcon.
