Grizzly Parts for G0463 - 6" x 22" 3/4 HP Mill/Drill

Fixture and Workpiece Weight - I bought a 6" rotary table. Bulky. I asked Grizzly for a weight limit on fixtures / work pieces, and I dimly remember @ 100 pounds. Maybe with that much weight at the end of a fully traversed table the mill wants to "tip". Securely fastening the mill's base to a bench or stand -MIGHT- change this. Might also be that much weight off-center would put more force on the lead screws and gibbs? YMMV.

DC Motor controllers ["Drives"] that have been mentioned being used:
XMT-1160 [SIEG part]
P0463220 [Grizzly]
Minarik MM23001C 
KBIC-125 

   Bought a G0463 Small Mill in the mid-2000s. Took it apart, cleaned and lubed it, re-assembled it [no parts left over! ]. Eventually put some cheap-o Red Chinese scales on it, hooked them up to a TTC Model 811-301 Display, cobbled together a Z-axis scale using a quill clamp, an aluminum base, and milled a pocket for a magnet.

FWD/REV switch is also called a Forward/Off/Rev [F/O/R] switch.

Motor 
ZYT-600 Brushed Permanent Magnet DC motor. 600w [0.8HP], 110v, 6.5A.

Looks to be a 90ZYT model, 90mm dia, motor length [sans square mounting plate] is 199mm. Haven't been able to pin the exact model down.

Seems to be discontinued [surprise! ]. I don't even know the manufacturer. Who is "TTC" ?

This uses 3x RJ11 jacks, and the cables are securely held into the Display Unit. However, the scales use a plug that requires perfect seating, and moving the table flexes that plug.
