No, it doesn't, so in that sense you're correct, Les, but its certainly one way to solve the problem in terms of production time. This is something I encountered about 4 years back when I attempted to make a ship auger type drill bit on the G0704 while I was building us an entertainment center. And again with a similar auger bit when I was converting part of our front deck to a wheelchair ramp alittle over a year ago so I could get the missus in and out of the house. In the latter case I needed it capable of drilling a hole at a low angle into the side of a 4x4 about 15" high, to anchor it solidly to the deck so I could drop a 46" tall plastic rail post over it and make the safety rails on one side of the ramp. Very solid feeling rail, it doesn't move with my 165 lbs leaning on it as hard as I can. That was the general idea. But it took many many hours with a 1/4" ball nose carving a 3/4" piece of cold roll that needed sharpening about 4 times a hole. Cold roll is not the ideal to make a drill bit from, but it got the job done. I should have done something like calculating the speed by translating it to radius, then to inches a minute. But TBT, I was much more interested in getting the job done, between the rapid dulling and time resharpening, it took about a day for each of the 3 posts to get them planted in a puddle of tightbond. Needless to say, I downloaded this conversion utility. On of the things I intend to do with this big gantry is make a copy of a thumbhole gunstock I carved by hand for a 50 cal BP rifle. Someday I'd like to find some purtier Maple. It shoots very well the way it is. My thanks to the author, apparently Shawn E.
