That looks allot better than the Anilam for sure, beachbum. I do however like the way the motor is positioned on the Anilam better. It's a bit more compact.

Another thing, is there a way to disengage the drive ?
Otherwise, why is the handle still on there in Ed's pic. ?
Yes, there is a switch to disengage the drive for manual operation. The handle on ours slides right off.

Great detail Sam...thanks !
Looks like the only way to use it manually with the handle would be to remove the 2 SHCS's and run the ball nut all the way down.
I guess you mean you can switch the axis drive off electrically, what is the procedure to operate the quill manually ?
Also notice another good use for Great Stuff foam in a can.
Neato,

found another pic, should have more oh and BTW the reason I fixed it this way and made it so narrow was it left access to the bolts for tramming the head without removing anything :)

That looks nice Hood, I wish I had made mine a little narrower, I had visions of optical limits dancing in my head when I  made mine . Mine stands off the front of the machine far enough its easy to get a wrench on all the bolts with no problem

Damn you're good.....reading my mind now. ::) That was my next Q. I noticed some that actually use lengthened coupling type nuts, and bolt the plate to them.
I prefer the access like you have.

I better ask this now....BEFORE you answer. :D
The old J head I have has a little fat motor...1hp I think. Funny looking housing, never looked real close but is it pretty simple to change it to an inverter duty 56-C type motor ? And if using a VFD, do you typically leave the belt on one of the mid pulleys then just use the back gear if needed ?

Hah...beat ya to it. ;D
