I just purchased another propeller for my garage. It’s a Hamilton Standard. I was told that it came from an AT-6 Texan, and that it has been sitting in a barn for decades.
I strapped it down for the ride home so that if I had to hit the brakes hard it wouldn’t go through the dashboard of the car.

It’s 8 foot across and weighs 175 pounds, far too heavy to hang in the rafters like two of my other props. (There also one I made into a ceiling fan for the garage.) So I built a stand for it and will display it near a wall.

There is some pitting on one of the blades , so I plan to fill that with body putty, paint the entire prop and apply new Hamilton Standard decals. I have not decided if I’m going to paint the stand, or leave the wood natural. I’m thinking about painting it OD green and applying military type stencils… I’ll wait until after the prop is finished to figure that out.
CHEERS!

Very cool!!

what are the part numbers on the clamshell halves. Might be the photos, but the hub looks small for a 12D40. It's probably me though. Nice find.

What are you going to do with it?

Thank you for asking. I’m always interested in finding out exactly what I am looking at. I cannot find any part numbers on the clamshell halves, blades, or on the cylinder. The clamshell haves are 9 inches across. Although I was told it was from a T-6 by the seller, it doesn’t really matter if that is not the case. Whatever it is, I was tickled to find it. I was browsing Craigslist while I couldn’t sleep… And thought $350 was a good deal.

I will display it in my garage… I have some other odd aviation items out there: A Hartzell 3 bladed prop made into a ceiling fan. Two DC3 engine cowlings painted with nose art. A T-6 wheel made into table. Two Stearman tail wheels are used in the light fixtures… There are others, mostly found on eBay and Craigslist.

I think a nice, dark, wood-stain finish would make your stand pop-out a little more than the plain wood. Cool find :aok

I think it would be cool to build a unit to withstand the weight and create a ceiling fan with it. Assuming you have a high ceiling.:)

I have already done it... This is the ceiling fan in my garage.

That's not what it's for.

What is the motor geared to and how much air does it move

I honestly don’t know the answers to those questions. It spins the prop at roughly 90 RPM. (Faster if you decrease the pitch of the blades - they are adjustable.) The most scientific experiment that I did with it was to smoke a cigar under it and watch how fast the smoke spread to every corner of the garage… It didn’t take long.

I would love to get a propeller to display in my home office room if possible; I do have a workshop in the back that would work if it's to large and hefty for the house. If I get one, I'd prefer it to be a WW2 era prop (perhaps a B-17). Any of you all have suggestions on where to look for those? I looked on some websites that had those those aircraft nose ceiling fans when I was remoddeling, but they just looked a bit kiddy.

Think about it the other way around: For example the propeller of a T6 Texan can pull a 5,000 lbs weight through the air at a speed of 150-200 mph spinning 2250 rpm. Now I'm not at all positive this calculation being accurate, but it gives some directions to thought: 2250 rpm is 25 times 90. 5000 lbs/25 is 200 lbs. If you could build a 200 lbs plane the size of a Texan, would it fly 150 mph @ 90 rpm? Notice that the weight should be balanced all over the plane, which means this is purely hypothetical.

Very nice Goalie!

Gads, I hate it when a question/comment bugs me to try to apply some sort of math to it..
If he's running 90RPM in the garage, I seriously doubt it's punching air out at 150+MPH. .. of course, if it did/could, that would be a spiffy cleaning-out option..
FYI.. the T6 Texan engine ( R1820 ) weighs 1200lbs, by itself.

The T-6 had the Pratt and Whitney R-1340 not the Wright 1820.
At 90RPM that prop would move little air compared to what it did on the aircraft. That engine idles at around 800 RPM and won't move the airplane at that RPM.

Guilty!! I was going by the A-27 which listed as a variant of the AT-6 Texan(BC1). It used the R1820.
The 1340 is only 930 lbs..

Thanks guys! From what I can find, the prop is not a 12D40 from an AT-6. But is instead a Hamilton Standard 2B20. While it did have some military applications such as on the UC-78, traces of red paint on the tips (as well as yellow) lead me to believe this came from a 1940s Cessna or Waco.
So instead of painting the stand OD Green, I may just stain it dark brown. But, I am still thinking of stenciling, “Hamilton Standard Mod. 2B20” on the piece that supports the center cylinder.

The prop is done.

Here is a pic of the worst damage:

I’m pretty happy with how it turned out!
CHEERS!
