Can you Identify my Propeller?

[Aaron Brooks Wolters]

No, I agree, I think it's either British or US. Are there not any patent numbers?

 

[quinn2234]

i believe there are some but there very faded and i cant make them out

Looking closer it looks a lot like the prop off of a L-19 Birdog but those props were probably used on a lot of different craft. I have several photos of a birddog with a variable pitch prop. I will try to find it and post it tomorrow. It's getting late and I need some sleep. I will leave note by my keyboard so I don't forget.

I found the photo and boy, was I wrong. It's not even close.

 

[quinn2234]

its worth the try haha, i enjoy the challenge anyways, havent researched so much in my life

Hard to tell without dimensions, but it has the look of a Curtiss Electric prop, maybe off a T6 Texan or similar?

 

[quinn2234]

that looks very similar ill get the dimensions and some clear pictures on friday

 

[robwkamm]

does it have a hole throught the middle? splines in there or tapered shaft? see how it mounts. it looks to me like a ground adjustable prop for a opposed type of engine. under 200 hp. post pics if the mounting area. and total length of the prop.

i believe it is this one because the back of the propeller is the original paint and is black.If you could give your opinion that would be great

Quinn - your first photo is terrible...

In the second photo, what are the numbers above "blade angle?" Additionally around the inner and outer hub, are there any numbers stamped into hub?

 

[quinn2234]

i cant tell what they say there to faded

How about numbers on the hub?

 

[quinn2234]

no sadly

 

[Shinpachi]

Thanks quinn2234 for your new photos.
Please let me resize them...

 

[robwkamm]

the hub looks like a beechcraft or beech-roby 214 electic pitch control prop. off a old bonanza or something maybe?

I believe you're correct

 

[Aaron Brooks Wolters]

Would that be the same as on a T-34 Mentor?

Not really sure - most T-34s had Hartzell Props and in some cases went to 3 bladed props. A Beech constant speed prop is mentioned in the TCDS for the aircraft. One interesting thing - the low pitch setting is 11.5 degrees - the same indicated on the prop. I'm going to do some more research.
