BEFORE you attempt it on a gun, try doing it on a piece of metal pipe (or several). Don't rush or work on it when not 100% focused on the job, If you have a "oops" keep working and try to correct it: that is what you will need to do on a real frame. Be a critical judge of the results, there is a major difference between good and I'd pay for that. Area contour, LPI, border and tool path restrictions are considurations. Give it a shot,
Have done a couple in the past, It will cost you about 75.00 to get the files to do this. Not such about the tool to get you started straight . You will also need a good flat file to. Good vice to hold the frame in and good light. and take you time, and as said try on something first. Just for starters Just m 5 cents jj Oh and no I don't want to do it.
I've done stippling on a few 1911's and have one in progress now that I'll try to post a pic of....not too sure how to work this website yet, hope the pic works out. Very good suggestions above about practicing on a piece of pipe fist as working on a contour is much different than working on flat surface. There's a very good book that may be of help to you. It details this process as well as many other customizations on 1911's and other pistols and
revolvers The book is, "Pistolsmithing" by George C Nonte
