the plug with center shaft is just a very close slip fit and held with the three set screws. needs to be easily removable to get the hub off the engine.

for hub removal i have a thick prop washer made of steel with the center hole threaded. remove center plug and nut from hub, mount the special washer with all six prop screws tightened down, long bolt with pointed tip goes in the center and is tightened against the crank nose. exact same concept as a regular puller.....you could make the hub compatible with a regular puller as well.

to remove the hub from mandrel just toss the whole assembly in the toaster and if needed use a regular puller or press it out in a drill press while still hot. shouldn't need a lot of force. if you don't want to remove the mandrel from the chuck then a heat gun will work.
