When I get it built I will share some pictures...
One more thing. I just realized that I need a 3/4 hole in the piece steel I have. That $10 pin just got a bit more expensive.... hmmm... Maybe a piece of pipe used as a bushing? 1/2 inner with 3/4 outer diameter.... just a thought.
I will have to see where to get a bit that big.
Look into getting a step-bit that goes from about 1/4" to 5/8". You can drill holes into material about 3/16 thick and it goes a lot easier then if you bought a 3/4" drill bit. Don't ask me how I know that on a large (1/2" and up) size bit it is very easy to chip the cutting edges and also very easy to drill triangular shaped holes. I don't have a drill press and a hand-held drill makes it all that much harder to complete these tasks. Good luck.
