Can anyone ID this giganamous spinner?



It's a 3 blader, mounts with 6) 3/8" bolts thru Lord isolators in aft bulkhead on a bolt circle(unless it's for a pusher, then that's forward bulkhead!), there are 3 handholes with Dzus fastened lids on same bulkhead. Looks as if it is NOS and must weigh 40 pounds...I think it's bullet proof!!!
This is out of my league! I mess with waaaaayyy smaller stuff. I bought it cheap enough and was considering cutting the forward dome off to create the large (relative) spinner needed for my Taperwing project. I am looking to acheive the J5 look but will be using a J6-9 (R975-11) as this.....

ATO NC6714
The shape of dome on NC6714 doesn't suit me and I thought the first 17" of this dome looked closer to what I need.

I really don't like cutting up good parts but if I can't find a home.......or if I can't find a proper part for my project......

Hi--

Hm. Where'd this spinner come from? To my eye--and what seems like a faded matt black finish on it bolsters the impression--this unit looks like it could be off a Canadian-built Lancaster (which was powered by Packard-built Merlins driving Hamilton props). Peter Whitfield could probably tell you straightaway.

If you haven't already, it might be worth contacting Vintage Wings of Canada; Mr Potter collects World War II aircraft and components, but also owns and flies a gorgeous Waco ATO...Mike Henniger of this forum volunteers with VWoC and could put you in touch. Just a suggestion.

Cheers

Doesnt look like lanc but could be mossie? any chance of pics looking inside it from the rear and a seperate pic of the back plate without the spinner fitted?

Don't cut it up!!

If you don't want it give it to a museum. But don't trash it. There are enough people out there searching for such parts.

I got it from some derilect yard in FL. It is not painted at the moment...it is raw aluminum with a greasey preservative covering the raw aluminum.



Here's the aft view.....



And a look at inside detail....

The horsecollar reinforcement around blade cutout and periphrial reinforcement are spotwelded...not flush riveted.

No, there's alot of screws on there and I don't have the time to take it apart at the moment. I would think these views should suffice to determine hub interface. can supply other dimensions if requested. I hadn't thought of a non-US application.....my thoughts kept coming back to some type of civil liner like an early Connie.



I didn't say I didn't want it.....the forward portion is just about perfect for my needs. if someone needed this intact for a FLYING ship, let's talk. My intentions were to make it FLY, if not all of it, then part of it. For static purposes, there are plenty of other alternatives.

Maybe with the diameter and length of the spinner someone might be able to figure out if it would fit one of the aircraft with an inline engine. If it is 6" too large in diameter for those it may have come off of a radial.

would it be mossie?

WheelsUp--

Florida, eh? Anywhere near Sarasota? I'm wondering if this spinner might possibly be a relic of Bud McNair's Turks Air/Aero Caicos operation, which flew ex-RCAF Canadair North Stars between Sarasota and points in the Caribbean (the Turks and Caicos islands especially). Bud had six North Stars, two operational and four for spares. All were scrapped in the 70s, with the four spares being bought for their engines (transport-rated Merlin 620s) by Cavalier's David Lindsay. Spinners would not have been of any account in that context. And the RCAF's Stars had three-bladed props and Lanc-like spinner profiles.

If the spinner is North Star, there's no chance of anyone needing it to go on a flyer...only one Star survives, and it is in the early stages of a longterm restoration to static display condition at CAvM in Ottawa. The spinner is, though, a rare Canadian relic if it is North Star; few parts remain aside from the complete CAvM example. There's a flightdeck in Alberta and a propeller in Picton, Ontario, and those are about all I can think of...

Doesn't look like a Northstar spinner. Here's a video showing the removal of the spinner and prop from the Northstar in Ottawa..

Is that a Hamilton Standard logo on the backplate? I always enjoy these "name that part" threads!

After watching the video you linked, I agree. That appears to have a 2 piece dome.


Yes it is. A real nice little 3 color aluminum oval held on with 2 drive screws.


Hmmmm..... A look at the EAA mossie with the Ham Std's........


It sure looks like it doesn't it?

But a look at I think a UK built ship....

This is from TH998. The blade cutout is not quite the same, but the rest is awfully similar.
A closer look at a Canadian ship might show the cutout more closely matched to the mystery part. Anybody have a closer look at the EAA bird's spinner cutouts?

Its an A-26 spinner. They were used for the On-mark Invaders that were converted into business transports. I happen to have two of them. (the spinners that is). Wheelsup- I wouldn't cut it up if I were you; they are worth a pretty penny these days.

Hmmmmm.....

It do look like an Onmark! I had always seen these w/o spinners as most all A26's. Tell me, this is like yours? Also, who would have contracted H-S to make these... Onmark?




Worth say....$2500? See, the problem is I need a large spinner dome of a very specific shape. It is going standard catagory so I am not likely going to get away with composites. I had just had a dozen 42"dia nose cowl spinnings made up for another application and I can tell you it's an expensive proposition! Relative, for a warbird it shouldn't make a true blue blink. Actually, $2500 would be a cheap price....a nice complete Montgomery spinner for a 2D30 would be right there at $1500.....chrome-able perhaps $2000+.
Knowing the ID helps to find a buyer, but they are nearly as scarce as the part and can be cheapskates!
Thanks for the inputs all. We'll attempt to find it a home. If anyone knows a user, head them this way. But it is not to far from the Sawzall.
Thanks again all for the suggestions.

I've always read that the On Marks used DC-6 spinners. Aren't the A-26s that use the short spinners a Smith or something? Weren't those props & spinners related to Constellation use?

I have taken a look at a few pics on the web and the DC6's I find not only don't look like this shape, they appear to be sectioned forward of the blades. This makes a forward dome and a band with the blade cutouts aft of the blades. This is just like the North Star had as shown in the video Steve Nelson linked above. The one I have is one piece dome. Here is a pic of a DC6 with the aft portion painted black and the forward dome natural......



It appears to pointy to me.

To be honest it looks Russian or German. It's just got an awkward shape.
