Yeah, and bet if you put a digital tacho on the quill with the mechanical speed control, it would vary even more wildly.

I have a tach and the readings (at the quill) are surprisingly stable. But then I may not know what everyone else would expect.

However, I cannot read 1/2% speed variation. In fact, I don't even know if that (17.5 rpm?)would make a difference at 3450rpm.

I doubt it makes any difference.

The piece being cut or trimmed certainly won't know the difference.

A lot of folks won't understand this but I am big on "sweet spots"... I have been running all kinds of machinery, both large and small since my age was expressed in single digits (I turn 70 next spring).
To me a tachometer, speed dial or even a quadrant with notches is there to allow me to quickly return to a previously determined by me "sweet spot".
I have a 20 something grandson that used to always say that when you are driving in the passing lane on the interstate that "the speed limit signs are just a suggestion".

To me the SS speed dial markings are just a suggestion... Sometimes I vary from those suggestions rather widely and find my own sweet spot. That spot can be a little different one time from the next, one blade from another, one wood from another.
I know some people follow those markings religiously but I do not.

That is as I think it was intended to be used.

Which is why on the Power Pro you can dial a speed in 1rpm increments and as long as you don't turn it off, it will return to that speed with the 'on' button. I am fully with you on that concept.

Speed limits on the interstate don't take account of "situations". Sometimes it's necessary to exceed the speed limit to avoid a collision, perhaps due to you or someone else having made a genuine mistake.

Orrrr drive slower to compensate for non-normal conditions(rain, visibility, snow, ice......).

FWIW tis 'illegal' to exceed the 'speed limit' for ANY reason.

Sometimes ya just gotta do what ya gotta to keep alive! Broken law or broken leg etc.

Regardless keep on the 'right':rolleyes: side of the road!;)(as in 'correct')

We need to keep in mind that those letter dial indications are approximations anyway. Why else not include 'rpm's' on the Mark 5.

The Mark VII included them so Magna did capitulate to 'popular demand'.

Also notice each 'spt' area includes a range to allow for varying loads(scroll saw dial[Slow - N] anyone?). A to S on the 'dial'

He "used to" say that... A few years later he was in a uniform carrying a badge and a gun. Then he met and married a girl who made him give it up. She is now history but I don't know if he wants to go back to law enforcement some day or not.
I have a son-in-law who was once a deputy in another county near here and a brother-in-law who retired a few years ago from the Sheriff's Dept. in Escambia County FL (Pensacola) after 38 years. I have a nephew who has been a jailer for many years. Oh, yeah, my 3 great grandfather was Sheriff of Spotsylvania County VA a looooong time ago.

Sadly not a single one of them ever owned a Shopsmith but I have tried to make up for it.
