[/IMG]Use what you have. This kept running in my head as I tried to figure out a solution that will not break the bank. Well, from the old racing days in stock cars, I have a taper ball joint reamer( two actually one for Mopar Upper arms and larger for GM lower A frames). Very close to the taper I want- maybe close enough to what I need. And, ta,da- I am a crazy person with 2 well equipped ShopSmiths. Why is SS relevant? Well, 1 1/8th Horsepower, less than .001 runout on the quill-a 1/2" router collet that does not require a Morse or Jacobs taper to hold tooling so any incidental side loading won't cause a tragedy, WIDE RANGE OF SPEEDS, And I have a gallon of "TapMagic." I think it is worth a try. And if I want a real tapered end mill, the one that hits my specs exactly is $59 and shipping. I also have a very good screwless sine machinists' vise with grooves to clamp to table. Once I scrounge the steel, I'll give it a try. Comments?jet
