Made some progress. Pulled compound+toolpost. Pulled cross slide screw out and pounded cross slide out. Intended to remove saddle and clean its underbelly but hit a snag.
The saddle wont clear the cross slide gear, I was already flexing the leadscrew to get this far. So in order to remove the saddle you need to pull the leadscrew. One thing Id change is to not cast in the leadscrew and feedshaft support on the right.
If that were bolt on a guy could just run the apron and saddle off the end.
So I needed to decide to go as far as pulling the leadscrew? Nope, everything feels proper in the gearbox and headstock. Ill clean as best I can for now and start putting it back together.
You can see a slight ridge on the main V there. 3.7 thou by fingernail. Actually Ive come up with a new product idea - fingernail calibration blocks that simply have a .001 .002 .003 etc step on them.
Anyways i got the ways cleaned off, the way wipers were all but gone for some time
So i cadded up some new wipers and printed them in tpu
I had taken the back keeper off thinking the saddle was coming off, you can see the original hand scraping and wear in it, about 3.7 thou by fingernail
Got the top of the saddle clean
A little bit of wear on the right side there.
Heres the cross slide ready to go back on
The cross slide screw above has a little bit of rolled over wear.
Once back on the cross slide had about .045 backlash, acceptable to me.
The main leadscrew looks almost new, very few threads were cut on here i think
So I just need to wirewheel the compound and toolpost and throw that back on. Then unfreeze the tailstock and I should be able to start on electrical - my thoughts on that atm are maybe a new contactor needed - the thermal overloads will see twice the current at half the voltage...
Anyways shes coming along nicely, might be running by christmas!
