Prop Straightening

Continuing with the home office/study/library build, I found some decoration via a damaged airplane propeller. I was able to straighten it out using the press and some 2×4 blocking. The aluminum is springy so the key to getting it flat is to bend a bit past flat, just enough so that when it springs back it’s straight.

There was a possibility that the amount of bending needed would create cracks. Based on prior experience with aluminum, I would expect for the paint to flake and for the surface underneath to turn white just before cracks occurred and I was looking out for this. If cracking had started, the plan was to heat the area with a torch until it was annealed, then continue bending – this would also have required repainting, so I’m glad it wasn’t needed.

For mounting it to the wall I cut a circle of 3/4″ plywood on the bandsaw. The circle is just small enough to fit into the prop hub, but too big to go through the smaller hole of the inner hub. Long cabinet screws then secure the plywood to a stud, sandwiching the prop in place. I plan to make another circle, paint black, and fit it into the hub to cover the structural piece.
