This is some of what I do.

I'd like to have that powered indexer to put under my toolpost on my lathe.. Talk about a ball cutter.. whoo hoo.. rock that post in a circle baby..

I did a manual one, I got blisters cutting a english wheel mandrel. The indexer I have is kinda crappy too, I have not taken it apart yet and fixed it.

I tried to invite a HSM local up to make "US" some ewheels on my lathe. He didn't fall for it.

I have a 10-2 in my bedroom (yeah - I sleep with a mill http://bbs.homeshopmachinist.net//biggrin.gif) - currently getting a new micro-stepping drive, and a new DC spindle motor for more power. The parts have all finally arrived, and - barring the inevitable interruptions - I hope to put it back together this weekend.

Some additional info on that machine on eBay -

It looks just like mine; so I think it's actually a 10-2, with the bigger steppers on it. I couldn't tell from the pictures if it has the ballscrew option.

The MaxNC machines have a Taig spindle, and it takes both Taig collets, and Sherline thread-mount tool holders. Little Machine Shop has some end-mill holders that fit this that go up to 1/2" shank size.

The primary complaint that I have with the MaxNC 10 is the spindle motor is too small - it's a 1/10th HP "universal" motor. As I mentioned above, I'm replacing mine with a DC Pittman motor.

If you can jog the machine, and turn on the spindle motor, the control works; as that's all it does (it's only a basic stepper driver, and manual speed control; all other functions come from the PC). There was no information provided on the 4th axis control, though; so I can't comment on that other than to say that it needs a second parallel port to run it.

I know about the Taig spindle and collets, but not the Sherline thread-mounted
tool holders.
Thanks I will try that. I am still learning on mine.

White Wolf Airsmithing make screw on holders for the Taig spindle (thus the Max Nc) that cost less than the Sherline ones. Also they have a greater range of sizes.

The sherline holders don't have the relief needed to screw all the way on without remachining the relief (as far as I know).

First thing you need to do on MAXNC's is replace the cheesy little shaft couplings (between the slide screws and the motors) with a solid clamp type that won't slip. Then you'll just be down to the backlash caused by relying on the end play of the motor bearings which were not intended for thrust.

Thanks
The experience of the people on this site is great and everyone is so willing to help.
You guys/gals keep making the tools/equipment I have just that much more useful
to me.

What do you make with your desk top equipment?
