Topic tags/keywords: lathe resource question refurbishing turning

Just before Thanksgiving, I bought this lathe from a local pawnshop for $200.00.
I tested the lathe before buying it and it worked ok, the only thing was turning the variable speed down to off the motor would slowly keep rotating until you shut off the main power. The knob was broken so I went to Radio Shack and bought another one. Over this past weekend I finished the base and set the lathe up plugged it in turned it on rotated the variable speed and nothing. So I checked the AC outlet ok, the power connections threw out the lathe including brushes ok, removed the potentiometer and it was not ok. Went back to Radio Shack and bought a B10K Linear-Taper Potentiometer (The B= Linear-Taper). Soldered the 3 wire connector on. I also cleaned out all the sawdust with canned air that was in the motor, and covering the circuit board. Put it all back together and still nothing. I have checked the voltage at the main line ok, at the circuit board I am getting a reading but it is very low.
This is what I am thinking that I should replace the circuit board and replace the Potentiometer with the exact Potentiometer from Sears because that one is switched.
I can’t find any information about this model on the Internet except for this
http://www.sears.com/shc/s/p_10153_12605_00929848000P?keyword=lathe this bowl turning accessories is bolted to the headstock of the same model lathe as mine
I would be grateful for any help or suggestions
The wood lathe is assembled with motor, speed control IC,
gear box and wiring installed as an integral part of the headstock assembly.
The 90 Volt DC motor has the following specifications:
Horsepower (Maximum Developed) ................... 2
Voltage (D.C.) .................................. 90
Amperes …................................... 12
Hertz …..................................... 60
Phase….................................. Single
RPM ….............................. 2000-10000 (Potentiometer and Circuit Board)
Rotation (viewed from left side)............... Clockwise

Go to sears.com, then go to parts direct. Enter the model # in the appropriate box. Your entire lathe minus a circuit board is listed, including the potentiometer.

Thank you for your advice I have done that. What I am looking for is information from people that have used this model lathe or something similar and had the same thing happen. Why?
Don’t have a big budget
Don’t want to play the order the part then wait game only to have it not work
Some parts are no longer available, so are there other resources or parts that could accomplish the same thing?
Thank you

Craftsman Lathe update;
I still have not received the parts I ordered for my lathe from Sears Parts direct I called them and they said that they are on back order from the manufacture, but their Web Site has them in stock I asked who was the manufacturer of the parts and they would not release that to me. So I looked up the manufacturer by the first 3 digits.
351 prefix is Colovos Co. I called them and they said buy the end of the month?????
Has anyone ever used this lathe and if so how did you like it? Model No.
351.21 7170

Thanks for any info in advance

I have the same lathe and I have put over $500.00 in repairs thinking each one will last. Never does. It is not working now and I am going to thow it away. By the way, I have put three circuit boards in it pluss all of the other electrical.

I had one, the tranny belt blew up 10 times in 2 1/2 years, but I had the protection plan from sears ($70) They spent a little over $3000 to fix it then when they discontinued it they spent $2000 to replace it with a Jet 1642. For me it was a great investment. There are many craftsman tools I would not purchase and a few that I would.
I wish you luck.
P.S. the tranny belt that they sell you is a gates rice paper version, but Gates also makes a kevlar version, contact them directly for a good belt, if you get that far.

I s**k for not logging in for a long time sorry all. But in my defense I was losing any ambition and funds I had to learn wood turning and put it on the back burner. The lathe is still down what I need is to fix or replace the 2 hp electric motor. Fixing means replacing the brush holders no longer in stock and brushes.

Still would like advice

Thank you

Did you get the issue with the inoperative lathe solved? I had just busted the potentiometeron my 351.217170 lathe during a move and thought about one possible problem that could have caused the issue.

When you put it together did you re attach the two grounding wires that are attached to the lathe case by the cover you removed to access the potentiometer??

The grounding wires attach to the case using the longer cover screw in the lower left hand corner of the cover.

The ground wires were attached to the bottom of the headstock separately with machine screws. And unfortunately not yet it starts and then stalls I even have it pluged into its own dedicated line AARRRGGGG

The motor speed control is probably defective. It is not available from sears, but a mc-60 form a treadmill is working in my lathe with some minor modifications. foxtrot

Thank you for a great idea. I was able to get a new circut board last year and found out it was the pot-switch and replaced that, so when I come across a treadmill I will try that.

If you want a new speed controller, the pot needs to be replaced with a 5000 ohm linear taper. Also a new speed controller can be bought for $50.00 and up. Mine was from Century Service 4278 Rurik Dr. Howell Michigan 48843.

Anything is possible. If you hook the motor leads to a car battery, it should run slow. It will measure almost a dead short when it is normal. probably .7 to 1.5 ohms. It is a d.c. motor rated at 12 amps 90 volts. I think that the brush’s are still available, but don’t quote me.

I was able to finally scrounge some parts together to get my lathe running. What remains now is to clean up the wiring and refine it.
