Hi all,
In the museum we have a large amount of Heinkel He115 wreckage. For the new season next year a new display will be made. Problem are the VDM props which are bent. They cannot pass through the narrow corridors in our building.
The engines are BMW 132.
The plan is to remove one blade from each prop.
Question,does anyone know if it is possible to remove a single propblade, how to remove a propblade, what tools are needed etc.
Thanks in advance for any assistance,
Cees

Sorry not got back!
I am sure Bruce is better qualified than I to comment, but the alloy blade is screwed into the steel boss, which in turn is screwed into the hub.
That probably doesnt help you much….

Andy, sent you that message but no reply yet. Will be looking at the props his saturdy. How do I know how to start?
How does the proproot fit into the hub?
Any help is appreciated.

Use something better than WD40, it’s not a penetrating oil although a bit better than nothing.
There was a thread a couple of years ago about the merits of various potions

Thanks for the replies chaps,
This particular Heinkel crashed in june 1940 after returning from a mission near Britain. It was based at Schellingwoude seaplane base near Amsterdam. It turned over when trying to land. The remains were discovered in 2003 during a survey before part of the water was reclaimed to build houses of what is now IJburg. It is fresh water so corrosion is slight, the props are in very good condition and we plan to soak the hubs with WD40 for a while.
Any info about the technicalities and tools is very much required, Andy i will send you an eail.

Hello Cees,
It is not that 115 that was recovered recently?
You have 2 options:
Remove the blade (very tricky)
Remove the propeller (much easier)
Propellers are assembled in facilities with powerful tools to close tolerances, but are designed for easy installation on engine.
Salt water wreck?
You will need to get special solvents to do it.
“Kroil” is likely the best on the market Get 2 cans.
Heating (blowtorch) and cooling (water) the pieces will help brake the corrosion, but practice on something before you put to airframe.
Be ready to cut a bolt. Sometimes you have no choice, and a bolt is not so valuable you cannot part with it. 😉
Best idea:
Cut a slot in the building. :diablo: :diablo:
And yes, it HAS been done! (then again, others have cut a slot in airplane :eek::eek::eek:)
When and where was this wreckage obtained?

Its possible if you have the right tool, but without it you will struggle.
I no longer have access to any of the tools.

Yes, it is possible but can be tricky depending on levels of corosion and distortion. Send me an e-mail, Cees.
Bruce might also be able to help.
