Speed Dial Repair

Greetings,

First post here.

Got the Mark V out the other day and fired her up. Went to dial up the speed and it 'felt' funny like something came off. Noticed that the speed would not rev up. Thought I would ask the group for any hints and tricks before I open it up.

Thanks for your reply.

Go to the next set of pages under this heading and look at at all threads under Speed Control and Frightening Noises. There are some excellant pictures there that should help you determine your problem.

If it felt like something came off I would say that it is the control sheave. Same thing happened to me. It took a little time and effort to replace it, but you can do it. I didn't think that the instructions that were sent were that clear, but the pictures that annbill.mayo are talking about were a big help. After reading that link and looking at the pictures I was able to adjust the speed after replacing the control sheave with no problem. If you do have a problem there are plenty of woodworkers on here willing to help. All you have to do is ask and they jump right in.

I had trouble with my speed dial just last week. I opened the machine and with a big blast of air from the air compressor, it cleaned it out real good and I have not had any trouble since.

I too use the compressed air for clean up around the shop but inside the headstock I use a vacuum.

I want to avoid moving that saw dust around inside the headstock because some of it is going to settle inside the motor housing. If enough settles there it will reduce natural air flow through the motor and lead to heat buildup.

Heat is the greatest single cause of motor failure.

Jake: You didn't say what kind of trouble you had with your speed dial. Maybe it was just a build up of saw dust, but it could be a lack of maintenance on the control sheave. I had trouble with my speed dial off and on and as it turned out the control sheave froze up because I failed to oil it. Check your manual and it will tell you how. A couple of drops of oil at the right time would have saved me so time and money.

Where are the pictures referred to regarding speed controller repairs? I can't seem to find them. I'm just starting a tune up on the 1962 shopsmith that I just purchased at an estate sale and need to get the speed controller working correctly. Thanks

Look under General Woodworking link on 11-27-06 and look for Speed Control & Frightening Noises. Read through the messages and you will see the pictures. They helped alot.

It was just kind of sluggish. After blowing it out, I oiled the machine and every thing is working OK.
