I have a DLE 30. I would like to remove the shaft the extends out from the thrust washer on the prop shaft to eliminate the use of the four bolts used to hold the prop on.
I have a plate with screws that exactly fits the bolt pattern and contains a forward facing threaded shaft that I can mount a prop on.
This eliminate the drilling the additional four holes in the prop .

This shaft is brass and is screwed into the center of the crankshaft where it meets the thrust washer.

When I go to grab it with a vise grips , I only bung it up and cannot get it to move.

Any ideas?
