30-40krag dude 2 Posted September 14, 2006 Report Share Posted September 14, 2006 i decided to do this mod today after reading about the positive results. i did manage to get one side fairly straight, but i wasnt so lucky on the other side. i did figure out a good way to keep things lined up (hence one good side) . too bad i didnt figure it out before i started . first off, a drill doctor is the way to go here. i sharpened my bit after 2 holes which helps keep the bit from wandering. next, you definatly need a starter hole. i tried using a center punch but it wasnt enough. so i took the smallest drill bit i could find, and trimmed a bit off of the shaft. the idea is to have the bit sit deep into the drill press chuck. i had only about 1mm of bit sticking out, which eliminated wandering and was just enough to make good starter holes. i would love to do my handguards next, but i think i'll wait till i pick up a cross slide vise...

SaigaShooter 0 Posted September 15, 2006 Report Share Posted September 15, 2006 The handguards are alot nice to drill than the gas tube. the bits bite into plastic much easier. though they are a pain to set up perfectly. Quote Link to post Share on other sites
