Flat belt lineshaft shifter - wanting to build one

I have a post drill with fixed/loose pulleys. I thought it would be a fun little project to rig up a short lineshaft and electric motor to power it when using small diameter, high speed bits (and I can still hand crank it for larger holes requiring slow speeds). The issue surrounds the belt shifting mechanism. Finding a purpose-built shifter (like a "Sim-Pull") is not likely, so something more akin to a foot pedal or long handled wooden lever is more practical.

I know that Joel Sanderson's blacksmith shop is filed with long, wooden handles for this purpose. I myself ran a water-powered gristmill with a long handled shifter, but we relied on a cable & hook to hold the shifter once it was in the "engaged" position. Most others don't seem to use this. Can anyone share some examples of home-built shifter mechanisms for their lineshafts?

Thanks!

Tarrantb...I was JUST sketching up an idea nearly identical to this, except the lever was one of two pivoting arms moving as a parallelogram with the shifting forks between them. Where did your forks come from? That setup looks PERFECT...thanks for sharing!

Got lucky and Found them at a locale antique dealer , before I found them I was thinking angle iron with a bushing thru both fingers, then set screw to attach to shaft.

Bill.. nice drive line setup you have there. Well used too based on polished face's of pulley's.

Another question: Pretty much all of the lineshaft bearing hangers that I've seen with shifter arms used a round bar for the shifter, as in Bill's setup. I purchased two hangers about 14 years ago that had rectangular holes in the shifter arms. Just wondering how common or unusual those might be.

Jeb, I have hangers that came with the original shifting rod. It’s just a wooden rod in the square or rectangular slots.
The original “shifters” are hard to find for the mainshafts. It took me two years to find one locally.
I’m watching this thread very closely to see what you guys are doing. Thanks!

Do you mean a "round wooden rod in a square/rectangular hole"? Just checking. I'll get pictures of mine.
