Hi, I normally go with a basic nut made of out mild steel hex bar on my aeros (or a nyloc nut on occasion). On my most recent build I thought I'd complete the look and make a nice prop nut/spinner as below. Anyone got any links/tips/tricks how to get the shape right?

Any info appreciated as it seems quite scarce on the webernet!

Thanks,
Patrick

I face, drill, and tap a scrap slug in the lathe and screw the spinner blank to it with a stud. I rough cut by eye using lathe tool(s) followed by filing and abrasive paper to shape.
 
Using your dimensions, example shape on left is an Ellipse, shape on right is a Conic. For a one-off probably go with TLAR, just using a section cutout to guide. I've made them using method post#2. Just give yourself a bit of distance away from the chuck with your threaded spigot for safety.

Spinners on real aircraft come in almost any configuration, from blunt to really sharp nose. It's an "eye of the beholder" type thing!
 
Hi, I managed to have a go at this today. Thanks for all the advice. In the end I went with using a radius turning attachment. Happy-ish with the result as a first go but reckon i can do better. The trick is figuring where the centre of the radius should be as its somewhere off the workpiece in the ether. Should look decent when I anodise it.

Thanks,
Patrick
