Acer;
After a couple of bad experiences with rasps, I started examining antique rifles with a magnifier, to see if I could detect any traces of the rasp. I looked in all the out of way places that might not get quite so much attention. I only found evidence of a rasp being used in a couple of instances, on very plain hunting rifles. What I did discover is that, under magnification, many stocks show almost a microscopic faceting, that I feel is left behind from planes, and scrapers.
The little planes I bought some years ago from Harbor Freight were made in China, and are of quite good quality. When I say small, they are only a couple of inches long, and I always set them up for a minuscule cut. By making a couple of extra irons for each of them, with special contours, and investing in a good set of rifflers, i was able to eliminate the problems I was having with rasps. I do still have a couple of rasps, because I find it nearly impossible to build a pistol without them, especially in the butt area.
