Help - G-Code Circular Motion for CNC Milling

[sanddrag]

I need a little bit of help with making some CNC parts. I know very basic CNC code and setup, but I have not yet learned how to program to go in a circle. I am only hand coding by the way, no MasterCAM. I want to make some bearing bores (like 1.125" in 1/4" plate). I can send a CAD/Inventor file of the plate if needed. I would like to learn how to do this by using the raw G-Code. Also, if there is an easy way to do text by raw code, I'd like to know that as well. The machine is a HAAS if it makes any difference.

Also, if someone would like to make a CNC program in MasterCAM to make a shifting dog (that I made the Inventor model for) and mating gears, I would be very grateful and perhaps willing to send a shifting dog to the writer of the program once successfully machined.

Thanks.
