This project started out to be a simple hanger to mount a display propeller that I carved.

One thing led to another and this was the result. The most difficult part was making the jigs to get all of the angles and mating surfaces to come out square and true. The engine is modular. The prop spinner is the nut that tightens it all. There is a 3/8 threaded rod that mounts to the wall bracket and then all of the components slide on with the spinner holding it all tight.

The propeller measures a little over 2 feet in diameter.

Maple, Alder, Cherry, Oak, Walnut and a little Birch and Poplar for the woods. The finish is lacquer.

Regards,

Beautiful! Precision engineering in wood as well as being very much a work of art. Wow!

Hats’ off to you. I hand-carved/shaped/snaded a propeller for a childs toy recently and it was really tough to shape it well enough that it had a rough balance, though it would not hold up to real engine RPM’s. Here’s a question you may be able to answer: It seems to me that all the wooden props on WWI aircraft were just varnished wood, not painted. I may be wrong about that supposition, but most old photos show this. Any technical reason for varnishing rather than painting?

BTW, that is very cool work!

Hi all ... Thanks for the comments …..

Tom,

I have seen the props either varnished or painted although the painted ones are not common. I think the varnish was used because it held up better and was easier to maintain and it was the common finish used in the furniture industry.

In the early years most of the props were built by business like furniture and piano manufacturing companies. In the realm of paint versus varnish not much has changed. I think I’d take issue with anyone who painted one of my props.

Here is a link to a site with a ton of of info about the old wooden props.

I work as a volunteer working on the older wood and fabric airfrafmes, engines and props. It’s a lot of fun just hanging out around all of those old engines and airplanes.

I agree. I used to skydive quite a bit in my younger, wilder days, and we shared a hanger with a wing of the CAF (Confederate Air Force). Even spent some volunteer time with them, polishing parts, doping fabric, etc, and just general help. They returned the favor by letting drop out the bomb bay of a B-17! Great bunch of guys trying to maintain aircraft that are getting rarer with each passing year.

This is really an impressive looking pice. Lots of detail. I have a friend that races model aircraft…pylong racing…he carves his own props for engines that spin 20,000RPM. Carving that prop is no simple effort. Nice!!

If the valve gear was on the backside of the cylinder it would be a perfect rendition of a Kinner 5 cylinder radial, but then it would be a shame to hide the work you did behind the cylinders. Very nice. That would make a nice addition to my study. I appreciate old flying machines as much as I do woodworking. Nothing beats the mechanical symphony of a radial engine.

Cheers
Mike

Don’t know how I missed this one! That is fantastic!

My grandfather used to make props during WWI when he was 15. Pratt & Whitney I think.

It looks like it would be hard to turn the engine when the propeller is mounted in the lathe.

That is sierously cool. I once had an opertunity to walk through a cropduster manufacturing plant they made everything from scratch—except the radial engine. Got to see one uncrated, brand new, one of the most beautiful machines ever made.
