Thank you, Photomancer. This has provided me with quite a bit of useful information. This lets me know what kind of metal to purchase, but I think the accuracy I’m looking for will require the use of the Bridgeport, which I am not trained to use. Who should I consult with to get a few precision 1" holes in approximately 3/4" to 1" thick cold-rolled steel? I’ll need approximately 22 holes drilled, give or take a hole. I can provide the necessary bits. The bushings will likely by nylon or brass for the guide bars ( thank you for that term. I did not know what they were called ) Can you recommend what type of steel for the polished steel guide bars?
