Started the Prop Spinner

April 4, 2020 – I pulled the prop out of the box and started the spinner.

The first thing to do is to locate the position of the front plate in the spinner. It has to be centered nearly perfectly so the spinner doesn’t wobble. This was kind of a pain. I figured out that the back edge of the plate is 8 7/8″ from the aft edge of the spinner.

As best I could, I drew lines around the edge of the plate in the spinner, then I measured the distance of each line. Yup. Each one was 8 7/8″ from the spinner edge.

Then I got the prop out of the box. I was concerned about how it would be to handle, but it wasn’t a problem by myself. I do think I’ll get help when I hang it on the engine, though…

I installed the spinner backplate and the front plate onto the prop hub.

I have to do the cutouts in the spinner for the prop blades. I wasn’t sure how I was going to do that, so I did some searching online. Turns out Hartzell has cutout templates for the Vans spinners. You just email them; they need to know the prop model and what blades you have. They emailed me the appropriate template.

Note that this is for MY prop and blades. I’m not showing you this to share the data with you, only to show you what it looks like.

Here’s the template in place. I just cut out one image and used it on both sides of the spinner.
