ACME 540 on a '82SN.
Picture taken after 20 turns of valve compound. I'm seeing the rotation marks along the entire taper length, but it seems to be a little darker near the end. This is my first time fitting a prop so I want to make sure it's done correctly. Do I need a few more rotations with the compound or is it ok?

Keep going! Notice the real high spot at the forward end of the taper. The blue should be even fore to aft. I also recommend some finer lapping compound.

What does the inside of the prop bore look like? You want at least 80 % of the ID to clean up.

After using the compound again, the prop bore has a smooth lapped finish through the entire length.

Considering how fat off the taper fit was, I suggest checking with the Prussian blue again. |
