It doesn't look like anyone else is going to respond so I'll put my two cents worth in. I hesitate to use the "D" word (Dremel) in a gunsmithing blog, but that is my tool of choice for action rails. I can have one done with a Dremel before I can even get my mill set up. I start with a carbide burr then finish the job with a Cratex point.
Go take a look at a 700 action and think about what you are doing... if you stand by your comments you need to stop working on guns.
IdiotO should never have started...
