what does it mean when you turn the speed dial and the motor speeds up but not as fast as it should and when you arrive at, saw speed, it takes a couple of seconds for it to reach max rpm.

everything is turning, pork chop is moving, belts are tight.

It's not a big deal just curious.

on another point of interest.

when stick your hand in the cut-out (logo hole), if you are older and take aspirin daily, your skin is thinner and you bleed easier----so wrap duct tape across the back of your hand to protect it- duct tape is thin enough to still allow your hand to fit through and tough enough to save your skin.

Lubed/cleaned the floating sheave/motor shaft lately? Ditto the control sheave/shaft. Something is 'sluggish'. Most likely the floating sheave.

more than once, ss hasn't been run or maintained for 5 years from PO

I had a similar problem once in one of my previous residences. It wasn't the machine that was the problem, but the power running to the house. The ground was... idk not connected tightly or something. I do remember it was the ground wire connection to the house from the power grid. The electrician fixed that and my SS was literally up to speed.
I just mention this in case you go through all of your maintenance procedures and suggestions from the forum does not fix the problem.

Determine if the floating sheave moves in and out freely on the motor shaft. With the belt cover off, adjust the speed and note the movement of the floating sheave. If it moves slowly and coincident with the slow acting 'speedup', it probably needs cleaning as well as lubrication. Increasing the speed is dependent upon the floating sheave responding to the opening of the control sheave by squeezing the belt to a larger diameter position on the pulley.

P.S. If yer lights are not 'flickering', you probably do not have Dasgud's scenario.

Please note the motor runs at only one speed!!! All changes in spindle speed are related only to the changes in belt and sheave position.

Your problem has to be with the sheaves and/or the drive belt.

Most overlooked is the motor shaft (The lower two sheaves). This is best lubed in the drill press position. Spread the spring with a screwdriver and put oil on the inner shaft as well as in the little hole. Then lower the way tubes to horizontal position and using your hands, pull the outer sheave away from the inner sheave several times. You should feel it begin to slide more easily.

Farley, pull off the drive belt and power it up. If you have motor problems you will have the same symptoms. If the motor runs smooth, you need a very thorough clean and lub job and maybe some bearings.

I guess the best way to have lubed this one was in the drill press position.

Once that was done, the speed was as it should be.

thanks all for taking an interest and giving suggestions.
