Thanks Guys, I did see those @11. The 2 quill blocks, are they just variations of the same thing ? Like for 2 different machines ?

 Here's another : http://cnczone.com/forums/showthread.php?t=8749

Ed, any backlash in your beveled gear drive ?

RC,
   I believe the quill blocks are 2 different pictures of the same 2 parts.
Should only need 2.

 Surprisingly the bevel gears have no backlash, contributing to a little noise, which you can't hear with the spindle running.
 They are well lubed. BTW, checked out the other site you posted.  A little overkill. Reminds me of the z screw on Hoods mill. :D
Should have enough power to broach keyways. ;)
This should give you something to sleep on.

Sure Ed,
Looks to me like the blocks in #11 are 2 designs, each of which would work. I like the solid one better than the one with the collar/spacer.
See ya tomorrow bud.  ZZZZZZZZZZZZZZZZzzzzzzzzzzzzzzzzzzzzzzzzzz...............................
thanks

My ISP changed all of the sites I had and I forgot to update to the new server so all my pics have gone now :(
Heres one pic I found of the complete assembly I made, should have more, the important thing is there is a slot in the back that lines up with the step at the front of the head. This is the first part of the Bridgeport head that is machined and everything else is referenced from this point when they machine the quill etc so it is the logical datum to have your quill assembly fitted to.

Hood,
I can see two counterbored slotted bolt holes at each end of the long slot. Looks like you may have drilled and tapped the head at the datum pads for mounting.? If so, is this all that holds the assy on the head ?
I like it....much slimmer design than JD's.
Thanks,
RC

The lower plate bolts to the hole that the old depth screw was in and yes you are correct, I drilled and tapped for 2x 6mm cap screws to hold that part on after the lower bolt was tightened. I probably have more pics of it at home, will look see if I remember ::) if I dont post bump the thread.

Oh..I see now. The motor is UP on yours. JD had the pulley on the bottom of his.
Thanks HOOD,
