Brad, Start by reading the original manual cover to cover. Don’t rush into anything and think you know everything. Go slow. Watch videos. Ask questions on this group. You will find many members here

Looks like there is a vital piece missing …. the other lathe!

I have both an SL and a 3. There's info on my blog covering both machines and the accessories that I've acquired for them as well as the use I've put them too which is small scale model railway stuff.

Here is a photo of what all came with my purchase along with two original wood storage boxes. There are more than a few duplicate pieces so I think there were two at one time. My interest is in model

Also have a look in the Files section here. You will find the original handbooks for the DB/SL which include basic machining information. Note that the DB is an earlier version of the SL, and there

Among many others, Mr. Pete222 on youtube.com. One thing I learned the hard way is that to get your stuff made correctly, you need to be able to measure correctly with calipers & micrometer. There's a

I'm the new owner of a Unimat SL and have no prior experience with metal machining. Can anyone recommend a source for educational videos on the basics. -Brad

No, the unit I purchased is an 8 inch strip of plastic aluminum with a reader bar. -- http://www.homemadetools.net/ forum/ OFF- SET-tailstock-center-65965#post105972 http://www.homemadetools.net/

This is what I ordered off Amazon: https://www.amazon.com/gp/product/B000FMYQIU - 331 Buna O-Ring, 70A Durometer, Black, 2-1/4" ID, 2-5/8" OD, 3/16" Width (Pack of 25)

What size and what durometer reading for those o-rings? Best Regards, Andrei mailto:calciu1@... ________________________________ Sent: Friday, May 3, 2024 9:13 AM To: Keith S. Angus

I am currently using Buna N rubber orings. I do have urethane stock to make my own but never got around to making a welding fixture. A project for the future! -- http://www.homemadetools.net/ forum/

Another check is check for short circuit from the windings to the shaft of the armature. Put your ohm or mega meter from the commutator segments to the shaft there should be no reading.

Check for carbon packed between commutator? segments or shorted or open windings, you need a low reading ohm meter for an accurate check.? Perhaps run it on about 6 volts and load it down and check

Yes, and no, and yes, and so on. Traditional magnets used in DC motors will lose their magnetism eventually. They can be re-magnetised, and sometimes you can get modern replacements. Modern rare earth

Good points, Bill. The Neuton mower was a simple arrangement of battery pack, switch/relay board, and motor. After removing the pieces from the mower carcass I simply charged up the battery pack and

Hi Tim if it has ceramic magnets they will loose their strength due to heat. If you find the motor runs hot in a short period of time they have possibly lost their magnetism. You might be able to find

Is your battery capable of providing 500 watts of power? Is your wiring capable of carrying nearly 21amps of current. That's what you're asking your power supply for.? I have one or two supplies that

In the model railroading world, permanent magnet DC motors definitely have problems with magnets weakening.? The result is that the motor loses power runs hotter. Some have put in new magnets which

DC motors wear out. Think of car starters and even back further to car generators. They had to be periodically taken apart and the armature turned down and new brushes installed. Most of the new

Hi Tim, I’m not sure it applies to older DC motors but I do know that you can’t take a stepper motor apart without damaging the magnetic field. The structure around the armature serves as a
