Thank you.

*Keith, * I did a search on EBay for Unimat belts Doug Feistamel and it did not return anything useful. Do you by chance know the Seller’s Web address? Dick

Keith, Thanks for the advice on the drive belts. I have both standard and low speed pulley assemblies. I also have a 10 foot roll of 3/16” clear polyurethane belting from McMaster-Carr. I plan on

Modern polyurethane belts give loads of grip (get a set from Doug Feistamel), so you don't need toothed belts.The desire for toothed belts comes from one of the older books where the author goes to

Jeff, I noticed your White Buna N belt. In thinking about the belt, I wonder how well a toothed belt and corresponding pulley would work? Is there a good reason why stepped pulleys would still be

I'm sure the data is online. The only thing I can tell you is you need a resistor added to match your motor if they're still the same. They are a bridge rectifier. Neil

There is a way to protect the speed controller from reversing too quickly. You feed the output through a bridge rectifier. Connect the speed controller to the AC inputs, and use the +/- outputs as

It's not.upgraded to CNC. The owner has just added a power feed using a stepper motor.? But that won't really work with the longer rails. Regards Steven

I went to Maker Space in Melbourne Fl today to do some woodturning. (http://www.melbournemakerspace.org/) I saw this Unimat lathe sitting on a table. Don't know any other details yet. Looks like it

You can start packing up the controller.? I bought it this morning.? I have a Machinex lathe, a compact 5 lathe, and a Taig mill, all with 90 - 125 volt dc motors.? I am sure I will use it on

Hello: I would suggest a reversing switch. It is very handy to back out taps. On my big lathe I often cut on the back side in reverse. The chuck backing off is a risk, but if it is tight it should

"On my power box I have two sockets for the motor - one direct from the 24 V, the other from the speed controller. The direct one has a forward/reverse switch, but not the speed controlled connector.

Keith, As I have no use for my KB motor control I listed it on EBay. https://www.ebay.com/itm/KBMD-240D-Multi-Drive-/234203164545?mkcid=16&mkevt=1&_trksid=p2349624.m2548.l6249&mkrid=711-127632-2357-0

Jeff, Thanks for posting the pictures. It helps to see and understand what you have done. Dick -- http://www.homemadetools.net/ forum/ OFF- SET-tailstock-center-65965#post105972

The power supplies are often quoted as being suitable for LEDs, but you'd need a lot of LEDs to justify 24V at 10A! Really they are general purpose power supplies - use them for whatever you like. The

Photos of the motor taken apart, easy to do, just two long screws. Put the end plate with the brushes over the armature shaft first and then put that into the stator tube when putting it back

Some photos of the motor end plate mods and the "top Hat" for the mounting screw all done on the Unimat.?Jeff

Measured full output speed of this motor was 3431 RPM. I drilled out the pulley to 8mm and it fit the motor shaft perfectly.?Jeff
