My brazing has been better than it is right now because I really need to get my cataracts removed. It's hard to do if you can barely see what's going on. Oh, well, getting old stinks, especially if you don't wear sunglasses.

I have found that an abrasive buff on a dremel works well for removing flash. Better than expected, really. I just buy the cheap ones from Amazon and don't stress about how fast I go through them. I also like how it highlights areas that I need to file, sometimes things blend in a little too much (see aforementioned cataracts)
