I could not find a split taper bushing with a 3/8" bore, so this was the cheapest and best way to go in the end. I did not have to rebuild everything else, just modified the pulley...worked well and I sure learned a lot.
One of the set screws is on the flat part of the D and the other is 90 degrees to that one.
I ended up welding a 1/8" steel plate to the shaft and bolting the plate to the pulley using 1/4-20 bolts.
It looks pretty strong...I will be testing it shortly.
Here is a picture after it was already...
I am learning that set screws are indeed evil....so basically I should never use a 3/8" shaft then either. I cant seem to find a keyed timing belt pulley anywhere which means I need to rebuild/replace almost everything that I have built so far.
I am working on getting you the technical...

Hi,
I am having a problem with my pulley slipping on a D shaped drive shaft. I just read the referenced thread and learned from Compositepro that a D shaft isnt designed for high torque operations. I suppose I made a few assumptions, one being that this is not a high torque...
