      I figured as much, I did get two quotes from them. $1125 was with the taper
      bored out and $820 was a solid piece. So they'd charge $300 to bore out the
      taper.... ouchies.

      I'm just gunna buy one from homeshopsupply.com and be done :-) I'm going
      to get the 3/4"-16 thread, and bore out and tap my backplate for my chuck
      using my Mill :-)

      I'll keep eveyrone posted as to how that goes...

      thanks for the help all!

      One reason for the cost is asking for .001" tolerance everywhere, when you
      don't need that tolerance. Try drawing it with only tight tolerances on the
      bearing journals and the chuck shoulder. Don't ask to bore the taper,
      unless you really can't do that your self., and have to have it.

      My first experience with a machine shop netted the same price structure,
      because I had toleranced everything to +-001" The owner kindly showed me
      how to decide what was important, and what wasn't, and we substantially
      reduced the price.

      With looser tolerances, they can do a one-off on the manual lathe at the
      back of the shop, rather than write code for a CNC machine.

      And don't forget, there are hundreds of machine shops. You just need to
      find one that's hungry. And friendly to likeable fellas <grin>
