Since it's 06/02, I thought today would be perfect to start this thread. IMO, This is the most cost-effective and capable lathe for the buck. It should be even more capable after CNC conversion.

G0602 TEARDOWN, CLEANUP:
http://crevicereamer.com/Page_87.html
I intend to CNC the Grizzly G0602 in 3 steps:
1: Quick, temporary and cheap using the stock screws.
2: Permanent mounting using Acme screws. Almost everything changes, and the X stepper will become a 381, but most of the Step One parts transfer upward.
3: Drop-in ball screws upgrade, which will fit the same mounts as the Acme uses.
The metal hasn't arrived, so I'll just bring you up to date with progress so far. Ultimately, this will morph into a mini Horizontal Machining Center.
The CNC flood cooling stand is not finished yet--still has some bells and whistles to add, (Electrical wiring/Accessory storage/Computer & CNC electronics/Final flood system & enclosure) but it's useable for manual turning. I am quite pleased so far, with its stability, rigidity and functionality:

So far, I have added to the lathe:
A $120 AXA QC wedge toolpost set from tools4cheap. It seems to be very rigid and well-made. I have no complaints:

A $22 Cam-Lock tail stock:
A $99 Grizzly 4 jaw scroll chuck:

And $3 manual turning stop:

I will do this conversion in three steps because:
1. Some of you may want to do a cheap stock screw conversion. I consider this temporary, but it could probably do quite a bit of work for awhile. It's also a good way to let the CNC take care of turning and threading the screws that follow.
2. Acme: This is a less expensive route than ball screws, and some may want to go this way.
3. Ball screws: Of course this is the most desirable path, albeit a little more expensive.
I've designed the parts to be maximally transferable upward from each step.
Home switches and threading indexer will be Hall effect sensors. I don't use limit switches for steppers.
1) STOCK SCREWS
This least expensive and temporary option will give capability to CNC turn the screws for step two.
A. Most of Option One components, including mechanical drive parts, will transfer to Options 2 and 3.
B. Motor mounts are simplified for rapid installation and quick functionality. Some parts will not transfer.
C. Spindle index and Home switches transfer upward.
D. Motor cables transfer upward with slight modification.
E. Flood cooling transfers in toto.
Electronics:
G540, Modified Keling 270 motor for X, Keling 381 motor for Z, Keling 48V PSU, Hall Effect indexing sensor and Home switches.
Estimated total electronics cost: $450
First up will be stock screw conversion--Just waiting for the metal.
