Denford Starmill - replacing spindle

[Doddy]

Just an update

I decided to bolt two rails onto the dovetail and mount a sled onto those, with a bracket attaching the base of the sled to the orginal Denford Z-axis positioning plate.


Picture 1, shows the basic sled, provided curtesy of a member on here in response to an RFQ.

(Also, the neodymium magnets on the right rail tells the tale of my hand-drilling the cast iron of the original dovetail)



Picture 2 shows the spindle mount attached to the sled. An early picture - was yet to be wired (the copper pipe in the background suggests the minor distraction of replacing an indirect-heated cylinder that was leaking, that somewhat halted play on the mill).



Elsewhere on the site I've discussed the problem with wow/flutter on the spindle, ultimately overcome with using RS485 between the computer and the Spindle Controller. At this time everything works as I'd hope it to.
