O.K. a real newb question here.....sorry if its been covered but I couldn't find it in a search. How do I polish? I've got a dremel tool and a willingness to learn.....I've got a marlin lever which I'm converting to a "large loop" design to start with. I'm cutting the lever, bending it to the shape I want then welding in a piece of metal to re-join it.....how do I polish out the weld points? Once I've practiced on this I have a Husky action which I would like to true up a bit.....any advice is appreciated.
