New G9972Z setup

[Road_Clam]

Think i'll start a thread going through the setup process. So phase I was to get it off my trailer and into my shed and up on my motorcycle lift table for uncrating. I though this was going to be a PIA but with some rigging straps and my hand winch and my ATV ramps the transition from trailer to table went very smooth and quick. Phase II is inspection and correcting the typical China poor assembly. Already spotted several issues that need correction. #1 is the cog belt alignment is way off , easy fix just needed to remove a spacer behind the upper pulley and now all the belts align nicely. #2 is the thread dial indicator is skipping, and that just needed to be loosened and adjusted to better mesh with the lead screw. Spent today with the spindle break-in. Tomorrow I start to disassemble and clean. Lots of oily grit everywhere.

Let us know if you hear any grizzly-like growling as you are unpacking it

I would have done an oil change and clean up before the break in......

No reason to change the oil twice. The original new oil is perfectly suited for initial break-in. Then i'm changing out to my trusted Mobil 1 gear oil and adding debris magnets.

A productive day today. Antisieze is my friend and I used it EVERYWHERE.

1) disassembled cross slide and the compound, cleaned and re-set gibs . Nice improvement with smoothness over the crappy factory setup.
Tons of sharp metal burrs everywhere spent a lot of time deburring edges.

2) dissembled the 3 jaw chuck as it felt gritty and dry. Added internal grease and this made a big difference in scrolling smoothness. They were pretty clean inside except for some paint on the pinion gear teeth

Progress is looking good!

More pictures are always appreciated!

So I a few issues with the drive system corrected today. Issue #1 was the fact there was SOOO much tension on the v-belts that I didn't even need to use the belt tension idler pulley. I literally had to use a screwdriver as an aide to force the belts over the sheaves. There's slots in the large pulley mount bracket and my guess is the mounting slots (or the M8 tapped holes in the head stock) were machined out of location. I removed the bracket and added about .090" to the length of the slots and this worked perfect. Now it's MUCH easier to slip the belts over the sheaves with just some minor force. I also corrected the pulley mis-alignment.
