I got started on making a new prop collar / cup, but circumstances
beyond my control caused me to close up the shop for today.
So far I machined out a circular blank by trepanning it on the
lathe, out of 1/16″ brass plate, and am going to try to “metal form”
it on the lathe, forcing it over a piece of round stock that’s machined
to the size of the prop hub.
No idea what tool I’ll use yet to form the cup, but I may have to anneal the
brass some so it doesn’t crack.
I’ve never tried it before, but have watched people on YouTube from brass pots, etc.
Prepare to be boarded!
