Hello,
I spent a good half in hour scratching my head and staring at my old 1955 "greenie" last night. I had taken the speed control apart and when I tried to put the belt back on to the floating sheave after reassembling the speed control the belt was incredibly loose. I did not notice when I took the belt off how it sat on the sheave but now it is riding about an inch bellow the edge of the the floating sheave rather than the 1/8" max recommended. Does this mean the belt is very worn or that the two floating sheave is too far apart.
Anyone know where I went wrong here?

Is the drive belt worn?

Try running the SS for a bit, up and down the speeds. See how it sits then.

Thanks for the advice and I just tried to run it back down to slow it stopped and felt like it was binding somewhere. I did not want to force it down any further for fear of breaking something. The best way to describe it is the speed control handle only turned about 1 full revolution (toward slow) before it stopped rather than the multiple times around it takes to take thh machine all the way from slow to fast.
I have attached a picture here with the belt and what i mean about it being so far down the the sheave. when there is zero tension on the belt.

Is the floating sheave 'floating', or is it stickey? With the belt off, can you slide it back and forth(you will be resisted by the spring[do not get anything caught between the sheaves][do not let it loose to smack against the fan sheave].
Is the quadrant 'hitting' something? Is the control sheave 'floating'?
Remove the speed control and verify all sheaves are not 'stickey'(lubrication needed). The floating sheave should go past its max speed position with the quadrant gear removed.
Shot gun questions - you find the answers!
Are you familiar with the high speed limit adjustment? You should be re-inserting the speed control with it set to max high speed limit.
Keep us posted!

Also while your shot gun is loaded. Try a high speed adjustment too.

Check with the belt removed that the motor floating sheave rim will close within 1/2" of the fan sheave rim being careful not to let the floating sheave go after compressing the spring. Ease the floating sheave into the fan sheave. Letting go of the floating sheave will drive the fan sheave into the motor housing and/or loosen the fan sheave set screw. Be careful with your finger tips too doing this step.
I set the high speed adjustment screw even with the thin nut face and part way in with the regular nut to start. Then do the high speed adjustment.

Thank you so much for all your help everyone. I am always amazed by how knowledgeable you guys are!
Well here are a couple answers for you:
-The floating sheave is sticky to say the least. Moving it is very difficult.
-I lubricated as per the owners manual before disassembling the speed control.
-Just did a high speed adjustment and it did help out a bit however, the speed control is very difficult to bring down to slow. It feels like it stops about 2/3rds of the way from fast to slow and the rest of the way takes some serious muscle to push through. (I have a 510 is excellent condition to use as comparison).
When the belt is off the speed control moves smoothly is well lubricated. from what I am getting from you guys I am leaning towards a problem with the "floating" Sheave not floating as it should. Would that make it difficult to bring back to slow speed?
Thank you again for all of your advice. I have greatly enjoyed this attempt to rebuild a shopsmith. If a little extra knowledge may be helpful here this machine was bought in need of much love. It took me about 4 solid hours to remove the rust alone! There may be more than meets the eye as this is a neglected machine but what can you expect for $40.00

Take off the spring and the floating sheave. Clean up sheave and the motor shaft. After all the gunk is cleaned off, oil the motor shaft.
