Speed dial adjustments

Post by ryanbp01 »

Since I have a break at work now, I though I would access the online maintenance and alignment manual to check out the steps to realigning the speed dial on the headstock since it now turns past the slow setting when I shut down. I had no luck doing that; the page wouldn't load. I quickly looked in the both manuals at home last night and could not find it. Any ideas?

It's not hard, although it can be a little fiddly. You have to loosen the set screw that holds the speed crank to the shaft by inserting your 3/32" Allen wrench through the hole in the side of the disk. A flashlight helps. Once you loosen it and pull off the crank, you can depress the indicator ring slightly and rotate it to 'Slow.' (or, if you've just done a high-speed adjustment, to 'Fast.") Hint: when it comes time to put the crank back on, insert the wrench in the set screw first!

The Sawdust Session video here: http://www.shopsmithacademy.com/SS_Arch ... _Belts.htm shows how to do it at the very end, since the HS adjustment and dial reset have to be done after changing belts.

Low speed adjustment

I know this isn't the intent of the original question, but I thought it might be of interest.
At one time I was buying and selling Shopsmiths on a weekly basis. I tuned up each of them before reselling.
I found the suggested method for a high speed adjustment to quite often leave you unable to get the dial all the way back down to slow.

I reversed the process so you first set the slow setting, then worked your way back to high. You need to get to where you have the top of the belt just barely below even to the outer edge of the lower sheeve and the speed dial set to slow.

From there, a simple adjustment of the allen screw that limits the pork chop range of movement makes it easy to set the high speed limit.
This always worked and resulted in full range of motion on the first try. Takes about 5 minutes.

Wouldn't that be the upper sheave?

You're correct.

It's been so long since I stuck my head inside a headstock I had to close my eyes and rack my brain for about 15 minutes thinking through which sheaves close and open. You are correct, the belt nears the outer rim of the upper sheaves as you hit Slow.
