DeadGuy, thanks for the step-by-step on disassembly.
does the x axis adjustable leadscrew nut have a part number on it? Your photos clearly show the nut.
Grizzly part# in my on manual calls it the Longitudinal leadscrew nut pt#1005613.
I think I have adjusted all the backlash out of mine, (4mm allan with long extension) so I’ll be needing one in future.
there seems to be a couple different ones, (bronze & cast iron) so want to have one before disassembly if possible.
i have cheap igaging DRO on mine, so not a problem yet.
like i said my machine is a Grizzly G1006/1007, but appears identical to yours.
