I wasn’t aware the rev limit for the engine was 2750, I always thought it 3500,it may be that my rev counter is not reliable as the engine seems to run happily at indicated speeds of 3000+ without any trouble from the limiters. All the internals on the mags have been replaced with brand new bits so they should work properly.
The pump is connected by a flexible pipe to the motor with a bypass allowing oil to go straight back to the tank controlled by a valve in the cockpit. The idea was to be able to run the engine without the prop spinning at all if required by by passing oil back to the tank without passing through the Hyd motor.
I would go along with Stuarts idea that two much pressure caused the pump to fail. The Hyd motor has got a built in pressure relief so that should have vented excess pressure, not sure why this didn’t happen.
You can see from the video the pump failed when I pushed the revs up not from throttling back.
It was never my intention to drive the prop any where near that fast just got a bit carried away.:o
Once the pump is fixed (unlikely) or replaced I will put another pressure relief valve between the pump and the motor and open up the by pass valve to allow more oil to by pass the motor, and keep the revs below 2500 RPM.
Once I ascertain the settings for a prop speed of about 100RPM I will retain those settings.
From a quick calculation I estimate the prop in the video to be running from 4 to 500 rpm when the pump failed.
The Hyd motor does not drive the prop direct there is a torque hub which gives a 5 to 1 reduction from motor to prop.
I have tried electric motors to drive the prop and they just end up burning out or turning two slowly, it’s a big prop to spin.
The engine certainly runs allot smoother under load and I am sure I am on the right track.
Building from scratch is always trial and error, I did my home work matching up the pump, hyd motor and torque hub but you never know until you try it. I am sure that if I had not driven it so hard it would have worked fine.

Tony I dont think you will find it had a specific use, it should be dated and that should used to establish what aircraft were around at the time with suitable performance. The use of knots ASIs has been debated here before and as a general rule it seems to be applied to naval aircraft during most of the war and MPH used by land based aircraft.

In the old days when vintage aircraft were required for filming in most cases the production had to make do with whatever was available, Harvards for Spitfires, that sort of thing, but with CGI today you can reproduce anything very realistically so its annoying when they make mistakes like this with Mk IX Spits in gray / green camouflage when they should be earlier models.
Yes I know its fantasy, but they made a big deal about the authenticity of the cabinet war room set so they dont really have an excuse.
As for the new “Dulux Daleks”…… well, if it ‘aint broke, dont fix it.:(

To be fair it was only DW which is totally fantasy it doesnt claim to be factual in any way and not to mention the BBC are pretty pressed for cash, We are working on another project at the moment and they are doing their best to get things right although the finance doesnt allow for total accuracy in all things. CGI works well from a distance but does not work well for close ups or changing paint schemes. BBC simply dont have the resources of Hollywood, whats their excuse?

I bet my “Dr Who geek” housemate that there would be a thread on here within 15mins of the end of the programme! I lost, it took 45:D

Graham, some good shots of your Spit on BBC3 showing the making of that scene.

They did allot of filming for DW confidential, unloading etc I ran the engine for them was hoping they would show it, perhaps it shattered the lense :diablo:.

She didnt destroy them but still scored a direct hit, all three Spits shown were the same aircraft the wonders of CGI.

I have used a metal detector around WZ on a few occasions and never found anything in contrast to other Ex Wartime airfields.
I knew a chap who helped build the road across the airfield post war and He uncovered a buried box full of incendiaries dealt with by the bomb squad.
He told me another story that stores from Norton Manor in Taunton. a D day supply depot were ferried in Lorries around the clock for several weeks to WZ and dumped.
I spoke to several land owners and locals and eventually to a lorry driver the originator of the story.
I came to the conclusion that it was a tall story he had told to his mates as when I checked where he said it had been dumped it was clear the ground had not been disturbed and was swampy meaning any pit would have instantly filled with water.
He also refused point blank to show me the spot even after being offered a financial inducement. :rolleyes:

Just been up in Liverpool and picked up a brick close to the site of the former Stork Hotel with DB carved into it. I reckon this could also be something to do with the Dam Busters !

How much do you want for it ?

Some of the pieces are quite big and even seem to have paint on them, taken together its quite allot of wreckage, if it is Dambuster its quite a find although i personally would not take a risk on it without stronger prov.

Greetings all.

My name is Greg, and Nick Stein has shepherded me to this site (thanks, Nick!), as he felt I could benefit from the preponderance of knowledge and wisdom contained herein.

I’m in the process of adapting Robert Stanford-Tuck’s biography into a script for a feature film. While there is information aplenty on Tuck, I find myself struggling with the portrayal of general RAF life in those days, particularly military procedure and protocol, as well as aircraft operation.

Living in the US adds to my dilemma. Were I in the UK, I’d most likely be spending time in museums and/or talking to RAF pilots and crew as part of my research.

With the group’s permission, I’d like to pop in periodically with questions. Some may seem unimportant or innocuous, but my hope is to make this film as accurate as possible.

Thanks for your attention, and feel free to ask me anything you like about the project.

G

Welcome, have you spoken to his nephew? I have his email if you need it.
