I.D. For A Short Stirling Part

Guys ,they are almost identical but all of the through fixings on our borrowed part are ”bolts” and in plain steel it looks like some of the through fixings on Hindenburgs part are alloy rivets?
also there are no brass components on our part , it is alloy, wood, stainless central bush, and steel bolts. I will keep looking for a number , differing materials may perhaps just be down to modification though or the part could be one of several bell cranks doing similar tasks. Kev

The parts are identical James..it has the same wood inside.thanks for that John…got a load more to clean up and ID if you can help.

The borrowed part shows no evidence of a cable attachment at its tips so I would assume that the timber work within it once extended out beyond the metal work and had attachments further out. it is very sim ilar to hindenburgs part but not the same, ie steel bolts and all alloy construction other than the timber within.

Hi Kevin

Hindenburg hasn’t put up a side view to show how thick it is, but I would have said that the parts were identical. It is an interesting thought that the wood might have extended beyond the metal parts. Along with the appropriate 429XXX serial number you might come to the conclusion that the only possible part this could be would be as part of the arms that operate the ailerons. I’d always assumed that they would have been solid metal castings but is there any evidence for that – could they have been wood?

0297375 – closest I’ve got is 0297373 which is part of the ballast box assy
4291320 – closest I’ve got is 4291352 which is part of the nacelle; it’s definitely not like the bellcranks under the P1 seat
6294364 – Closest I’ve got is 6294343 which is the Control C0ck at middle tank group

[ATTACH=CONFIG]242774[/ATTACH] and what about this hinge 0297375…..?

Possibly the fixed hinge holding the armoiur plating to the rear of the Pilots seat? I have a feeling that I’ve drawn something like that a few times!

Doesn’t look quite right as the metal it’s attached to has rivets that don’t appear on the seat back. Also your hinge has an interesting off set bolt.

[ATTACH=CONFIG]242777[/ATTACH] 6294364??? With brass bush in casting…crank pivot from under pilots seat???

[ATTACH=CONFIG]242774[/ATTACH] and what about this hinge 0297375…..?

Hmm,there’s a thought…I’ve got some of the under seat bits…will clean them up and check the numbers!!! Left a post on your Stirling Graphic thread too….stunning work !!

Here’s a thought:

While it do not seem as if there are any bellcranks in the wing near the aileron or flaps – what if one of the cranks under the pilots seat was part of the aileron control system and therefore attracted a 429XXXX serial number?

James

Hi Hindenburg

I can’t find anything like it on the aileron and mainflaps drawings or photos. I’m stumped for any positive evidence one way or the other!

Can’t find the part you put up either – does ‘look’ like a sump but no drawings I have match it – agiain no positive evidence one way or the other.

James

Thank you chaps…part of a ‘trim’ James?

serial number 4291320

Looking through the repair manual:

129XXXX Fuselage Parts
229XXXX Rudder and Elevator Part
329XXXX Wing parts
429XXXX Ailerons and mainplane flaps

Useful clue or red herring?

James

Just a guess but it could be a fuel tank sump with the water drain from one connection and the fuel line from the other one with filter.

Richard

Looks like a piece of oil cooler or tank Hindenburg

[ATTACH=CONFIG]242758[/ATTACH][ATTACH=CONFIG]242759[/ATTACH] whilst we’re on the Stirling I.D…and not wanting to hijack this thread,what’s this James??? Serial number looks like 72994?

[ATTACH=CONFIG]242757[/ATTACH] the other side…serial number is on the brass part on the inside…

serial number 4291320..I got a bit of Stirling wrong..?..oh the shame !!!!!have a nice Christmas!!! 😮

What’s the voting on the actual part then?

I don’t think that it can be the bellcrank that operates the rudder torque tube – it’s looks too small and surely the hole for the pivot would need to be as big as the torque tube? The hole for the pivot is really quite small. Though looking at the drawings of that part I can’t see how the rudder could turn very much?

There are two of these under the pilots I’ve found.

James

Nearly there James, in aviation terms its known as a bellcrank. Knew I’d seen something similar in a photo somewhere, definitely not tank though as was my first thought:stupid:
