I recently acquired a small Sherline vertical milling machine that was converted to CNC and sold to schools by Paxton / Patterson in the mid 1990's.

Although I did get the machine working with Mach3 software using a DB25 dongle, I found the original stepper motors lacking power and glitchy. So I stripped all the original electronics and installed new power supplies, motion controllers, stepper motors, and a parallel port break-out-board.

Today, I made an aluminum fixture plate and added a chip guard as can be seen in the photo. I also made a few Morse Taper endmill holders and some work clamps from steel.

Nice setup. I see these on fleebay all the time, well these and others like it. They always seem to sell for way too much, especially considering what you needed to go through to have a good working tool, replacing all the old and generations outdated electronics and such. Now that you've got it this far, are you considering something like an ATC? :)

Wow! That automatic tool changer is absolutely incredible.
No, I have not planned anything quite so ambitious at this point in time.

Thanks for the link.

Your welcome, I thought it was pretty shiny my own self. In the yahoo group for that mini tool changer, a few have just adapted the spindle porton and use it for a more traditional tool rack style ATC.

That's the exact same setup I got for my first mill. In my case, the Y axis on the driver board didn't work right, so I yanked the board and went over to a Xylotex box. Got the heftier motors (300 in-oz?) they sold with the controller box. Then I got bigger A2Z CNC XY axes for it with the Kerk lead screws. Works really nice.

These Sherline-based teaching machines are actually a pretty nice deal. I have had a Denford and a Lab-Volt. Both had nice steel cabinets with roomy enclosure for the electronics. Most of the electronics can be retained, requiring only a few new components to run from EMC2 or Mach3. The going price seems to be $400 - $600 for nice examples in working order. Another $100 will get them running on Linux CNC

May I ask where you're finding these machines for $400-$600? All the ones I'v ever seen are being offered for ~$1995 and up. Even with the Sherline at the bottom of my list, at $400 almost ready to go... I'd be thinking about it.

Edit - OK, I just found a Lab-Volt on ebay for $675. I guess they can sell for less than 4 figures.

I paid less than $400 delivered locally, from ebay. I then sold the original Micro Kinetics power supply for $50. I have tried to sell the original 3-axis controller, but so far no takers.

Well, I came out pretty well on mine. I paid $250 for the whole thing. The seller mentioned he had another part to go with it. Turned 0ut to be another complete Sherline CNC, same mill without the cabinet! I sold that for $150. Then I sold the main board out of the Lab-Volt, along with the control panel, for ~75 on ebay. Of course, I bought a few things to update it, about $100. So I'm at about.... $125
Now I have to get back to making it work
