I would use them for getting pits out, little parts like hammer, trigger, trigger guard and any other awkward thing like that. A few students have recommended getting a set of stones but no one has specified which brand or kind. We use sandpaper (with WD-40) and blocks of wood and that works well for big areas but for the little areas it's a little tough. In semester 4 we will be doing things like trigger jobs and they say stones work really well for that.

I have a similar type of stone I use on my ss knife. I think they would work great on fire control parts and polishing in general as long as one is very careful. What about using the round type for feed ramps? Anyone?

I'm a tool & die machinist we use the Falcon brand stones for metal finishing. They have many different types of stones that can help with many applications.

We also use die grinders with MX wheels like this to remove heavy pitting.

For smoothing/polishing larger areas like the sides of triggers and hammers, use a "bench" stone. Trying to see-saw your way across a wide surface with a narrow stone will leave an uneven surface.

Don't forget honing OIL as well. Some stones are used dry, some use oil, others use water for lubrication and to keep the stone from loading up.

A feed ramp would have to be in pretty bad shape to require stoning, but yes it's been done. Fine sandpaper wrapped around a wooden dowel works too. A final (high) polish would be done (very carefully) using a felt bob and polishing compound in most cases I believe. A mirror finish is nice, but not absolutely necessary.

What is the point of paying tuition to a school that has "instructors" that don't instruct? Don't they give you a list of the basic tools you'll need to complete the course?

JMHO here, but any instructor that puts a power tool into the hands of a novice gun smithing student need to be taken out in back of the wood shed for a lesson of his own.

I went on brownells. thier round files for polishing feed ramps are from india and in the chat they could not give me any information on the grit size. I am not comfortable with the lack of information. Do you have any?

Well to tell the truth, my hammer does have some pitting, and it has been a long time since I had my stones polished. Getting old ain't all its cracked up to be.

Polishing with stones is an art-form which takes quite bit of practice to become good at. It's not hard but you have to be a patient person with a sharp eye. The process is very time consuming and tedious, but the results are very cool.

The following link is a pretty good article on learning to polish with stones:

http://www.moldmakingtechnology.com/articles/teach-yourself-polishing

Feed ramps should be polished with round or half-round stones. edged stones will gouge the s**t out of a feed ramp.
