A small flat blade screw driver is the first tool that I would try to use to adjust it to that comfortable speed. I long nose pliers would probably be the second tool. How long is the remaining shaft?
The shaft is pretty much broke off flush with the back of the knob. Not much left to grab, but the screwdriver slot is a good idea.
What do tou think of doweling the two together somehow? then the knob would still be functional

I haven't used them, but there's a positive review on Amazon from someone who has.

If searching for substitute blades (non-=Shopsmith) for either the planer or the jointer, dp not over look the taper. The taper is there as a means to secure the blades in the head. I don't know if all blades are secured that way or not.

You need to know it's total resistance, and it's taper.(taper being the ratio rotational change to resistance change). They may be lineal)1:1, logarithmic, or something else. Lastly the physical dimensions(including shaft shape/length etc.

Truth be known, tubnik's solution might be the easiest and least expensive(both time and $$$$).
JPG, most of the time I consider myself "fairly" sharp but not highly educated...then...you throw out a bunch of big words and logaritheories that made me want to go home and watch the Disney channel.
I'm not sure what all that meant.........but I wanna do it cause it sounds cool.

How abouts I wish I could come up with an ol white plastic piece ta fix da broken one.
