hi, all! Got some info here: you can do barrel drilling and reaming in a lathe that's got at least 13 x 36 capacity and at least 2 HP with a 1 3/8 spindle hole. A company in VT makes and sells gun drills and reamers utilizing a mist coolant system of 100 to 120 psi. The mist system runs about $1150 and the drills that they make run around $100+ but any gun drill will work. There is a modification to the lathe in that the feed rate cannot exceed .0005 per rev. This is extremely critical using this system. The company is Sterling Gun Drills and they are on line. Hope this helps anyone wanting to make their own barrels. thanks, John
