Anayak "Exacto" Vertical Mill Rebuild, Part 2:
After that quick analysis, and then letting it steep out under a tarp for three or four weeks while
I cleared off my workbenches, it was time to get to work. With the help of my handy dandy
engine lift, I started by chopping off it's head.
I'll have to give it a thorough inspection later, and probably a full rebuild,
but for the moment, onto a pallet and under a tarp she goes.
Then the ram and column saddle comes off...
And then the table.
I'm not sure what was jamming the works, but once disconnected, the table slid off smoothly,
and with the table gone, the leadscrew turned nicely. Not sure what the issue was.
This is the drive end of the power feed, two bevel gears are supposed to go in between those two nuts.
Fortunately, the previous owner still had them in a bag, and they appear to be in good shape.
What wasn't in good shape, however, were the leadscrew nuts. This setup, for whatever reason, appears to
have no fewer than three of them, one of which has so much wear the screw can clunk around in it, and the
other two are so worn the screw can be slid through without needing to turn it.
Those are going to be expensive to replace.
With the X-axis leadscrew removed, the Y-axis handwheel and screw can be taken out.
And that frees up the central leadscrew nut assembly to be removed.
After that, we gut the electrical cabinet (very little of which we'll be reusing)
remove the internal coolant pump, and get ready to remove the knee.
All that leaves is a grungy, bare column casting, ready for cleaning.
Next up... you guessed it, cleaning!
