Balderdash!!! This is one of the VERY FEW TIMES I will disagree with you Dusty! Your text posts have always been some of the easiest to comprehend!dusty wrote:Ed, I am not too good trying to explain myself with words.

I guess you guys already know that.

Ed. If you would like to see a bit more of what is inside the Power Station, I'd be glad to pull the cover and the pulleys to show what goes on there.
I personally believe this is a real neat application of the sheaves. I understand that it is a rather primitive way to accomplish their function (a variable pulley) but I still think it is neat.

Dusty: I am wondering what your motor/inner belts look like at high and low speed position. Mine appear 'tighter' at HIGH SPEED. If I had adjusted tension at 'LOW" speed as you suggested, it looks like it would be even 'tighter at high speeds.
It certainly would have been]

Check my next post.
You ARE correct that the tension varies depending on speed control setting and the tension varies oppositely on the other belt.
Like you I am struggling to find a proper way to adjust motor belt tension.
My belt adjust shown above was determined by the limit of belt entry into the inner sheave. Any tighter and it would ride on the flange ridge near the center. This was done at HIGH speed setting.
In the low speed picture the belt appears (and feels) Looser!
This would be consistent with the mechanics of this concept.
From this I think that setting the tension tight at LOW speed will cause tighter tension at HIGH speed.
That was my reasoning when I did it at Low Speed. There is something wrong with our logic here.
Does your motor pulley align with the inside or the outside sheave pulley?
Which is 'better'(adjust at high or low speed)?
******RELATED QUESTION********
Since I purchased my PS used and in dubiously assembled condition, I had to improvise motor mounting. Pix below shows my attempt.
http://www.shopsmith.net/forums/attachment.htm?attachmentid=3070&stc=1&d=1231724039
The hardware from the top is 5/16 bolt / internal tooth star washer above the 'top' and fender washer /1 1/2" spacer / internal tooth star washer / nut / flat washer / motor mounr / flat washer / split lock washer / nut.
This places the center on the motor shaft about 5 1/2" below top. I am curious if your 'stock SS' mount places motor any where near that after adjusting tension?
The four bolts on mine are first secured to the stand with four lock washers and nuts. I can drop the motor and the bolts do not move. Then I have four nuts> followed by four flat washers>followed by the motor>followed by four lock washers>followed by four nuts.

If this is what I wrote, it is wrong. There are three nuts on each stud positioned as you have them above. The error is highlighted.jpg40504 wrote:Thank You for Your Reply!
First to answer your question. The motor pulley is directly below the INNER sheave pulley. The spindle pulley is 'IN' (away from end of shaft) almost as far as it will go. If positioned further 'out' the sheave pulley tends to drift out and rub the edge of the cutout in the top.
If I understand your description of 'motor mount' start at the top there are four each of the following in sequence: Bolt head>top>lock washer>nut>empty threads>nut>flat washer>nut>motor>lockwasher>nut. This seems strange to put flat washers between two nuts?????
BTW I did finally replace the 'rack and shaft assembly' and the guides. Though still 'sloppy' it doesn't wobble any more and runs smoother.
