Then the magazine well could dimensions could be marked in and some more wood removeds and to do much of the mag wall I find the smooth side of a farriers rasp to be the ideal tool. With the stock set level in the vice it is not difficult to use the rasp marginally off level to file in the draft of the mag well. chisels, scrapers and smaller files are needed to finish getting the metal in. Being able to turn the wood over and see from the other side makes this a reasonably simple operation.
