Can't keep it running

Make sure the speed control is ALL THE WAY to FAST. It makes removal of the belt much easier. Rotate with disk as described earlier to get it to 'fast'. As Bill said, watch yer fingers with motor sheave!;)

After testing the motor and finding that it runs without tripping the breaker you might want to take a break.

A good thing to do while taking this well earned break would be to watch Sawdust Session #11 where Nick esplains the ins and outs of "Cleaning and Lubricating the Mark V".

http://www.shopsmithacademy.com/SS_Archives/SS111/SS111_Mark_V_Maintenance.htm

You probably already have this but if not this is an excellent source of information (applicable only in part to your question).

This document was provided by Nick during one of the later Sawdust Sessions (#23 I believe).

The following is more information; this provided in Sawdust Session #24.

You have had some excellent suggestions, and maintenance is certainly in order.

With that said, you need to look at the external problems. You may very well have added more appliances & lighting, or a newer item on the circuit than you did a few years ago, which has increased the load on that one garage circuit that you have. This could account for the breaker trips. Operating the Shopsmith on a 15 amp circuit is marginal, even when it's the only thing on the circuit. Also, your circuit breaker itself may be failing.

You obviously need to install a dedicated 20 amp circuit in your garage for your Shopsmith.

Everyone has had good info. I would only add that you do not want to forget that circuit breakers also can deteriorate if tripped occasionally. I have cured several tripping breakers over the years by simply replacing the breaker. I see breakers often used as a switch and they can wear out from that too.
I would especially consider the suggestion to let it run on slow a while to warm up if you do get it started. Then run it up and down the ranges. Sometimes that is all it takes.

On that dedicated circuit, see if your neighbors garage is wired better than yours and if so maybe you can sneak over there at night and...

Thanks a bunch for all the help guys, I finally got it going.

This morning I lubed the sheaves as suggested and manully dialed it back to a slow setting, and then it started up fine, so I let it run for a few minutes before speeding it up and down (with no ciruit breaker trips:-).

The quill is still bothering me though, it is still binding. If I extend out it will only slip back about a inch and then it stops, if I move the lever it will slip another inch. I've cleaned all the groves, waxed it, adjusted the retaining screw and the tension but I still have this issue. Any ideas?

Now that you have it running (and know that you don't have a motor problem), give it a real good cleaning and lubrication.

Now for the quill.

Can you manually extend and retract the quill?

Do you seem to have full travel of the quill (when fully extended - how far out does the quill go)?

If you extend the quill and then let go of the handle - does it slam back into the retracted position? This should be a knuckle knocker so be careful!

"Can you manually extend and retract the quill?" yes

"Do you seem to have full travel of the quill (when fully extended - how far out does the quill go)?" Yes it extends all the way out.

"If you extend the quill and then let go of the handle - does it slam back into the retracted position? This should be a knuckle knocker so be careful!" No, like I was saying, even if I let go the handle (when it's fully extended) it only slips back an inch, then if I nudge the handle another inch and so on....?

Is the set screw that seats into the plow on the quill too tight? See this Sawdust Session, it may help: http://www.shopsmithacademy.com/SS_Archives/SS107/SS107_Quill_Maintenance.htm

No, I adjusted that by holding the quill extended, then tightening the set screw enough to hold the quill in place, then I backed off untill the quill slid back home

Back the set screw completely out of the hole. Does the quill return now? If it DOES, look at the sides of the 'plow'. Are there any burrs on the side walls. If so carefully file them back to the normal width. Carefully replace set screw being careful to NOT tighten set screw into the edge(make screw is centered in 'plow'.

Did you take the quill completely out of the headstock at any time. If so did you set the spring tension when you re-installed it?

These are two different problems/fixes. Do not get the two confused.
