I like the idea of symmetrically loading "Z". Since I originally put
up the pictures of the mount on my site I have removed a lot of metal
(eg. cutting out the rectangular side panel centers and slotting the
supports which go from the lower end of the motor to the upper end)
to further reduce the weight of the whole assembly (although the weight
of @13lbs doesn't seem to phase Z-travel at all).
I don't know how easy it is to see from the pictures but the motor is
mounted to the top of the headstock with a steel plate, special long
T-nuts and 8 Allen screws. Power is transmitted with a short XL timing
belt/pulley arrangement and there is an adjustment of @.750" in order
to tension the belt.
The whole assembly is very rigid and it has the advantage that I can
remove the whole assembly from the Z-axis (the cable that runs from
the motor to the controller box is @ 6 ft) and I have in essence a
kind of "general purpose - variable speed - power-head". I have an
aluminum base plate on which I have mounted a plate like the one on
the Z-axis (a \__________/-like cross section). I slide the head
onto this plate just like on Z (except now it is in a horizontal
orientation). I have several "tools" I am planning to build which
will be powered by this.
1. A small diameter blade modeling table saw.
2. A modeling thickness sander.
3. A tool grinding set up .
I recently completed another "head" for the mill which allows me
to mount a DEWALT laminate trimmer in place of the power-head
described above. I used an extra riser block as the start for this
and it works very well. When I'm a little less busy I'm going to
update the web site:
