I wonder if the counter weights are to prevent the tab from fluttering in case the tab cables are shot off and the tab becomes free?

The turnbuckle is safetied as prescribed in the maintenance manual. The wrapping is all at the rear to prevent the safety wire ends from slashing on the leather washer. It slides smoothly back and forth into the washer. Yet another complexity.

Here's the safety job on the aileron supports--

The cotter pin is twisted 90 degrees inside the bolt. I've never seen that before.

Would that weaken it, somehow?

Helping with a Hurricane restoration.... put Trig remote stuff in it. Seemed right. Factory wanted to debate the fact that we didn't hook up the intercom: It's a ONE seat airplane -- nobody to converse with! Hard problem was finding a decent IFR cert altimeter with a 6:00 clock baro knob as was the original. This airplane was actually manufactured in Canada so it has a mixture of British hardware and AN.

I thought the treatment on the rudder trim tab was interesting. Has small counterweights ahead of the hinge line just like a Piper Comanche rudder.

And I had to admire the safety job on one of the aileron supports. Every molecule pounded into submission.

Beautiful restoration -- heading to KOSH the gods willing. The complexity is just staggering! How did they build all this stuff?

Do you think looking at it that this was by design or layers of fixes on the fly?

There is a Britishness to how they do things.
And they refer to it as a Split Pin
I had a early 1950s 50 hr Inspection Manual for the Spit XVIII we operated for 6 years. INsp items were broken down by task, manpower and time. Things like Man A does X, Man B does Y and sometimes a Man C thrown in. Then it’ll say task should take 15 minutes to do. And there were NCOs thrown in the mix to supervise and keep workers on task and on time as well as supplies and stores involved. I never let the FAA see that Incase it gave them ideas.

Spitfire has about a 525 MPH VNE on the Griffon powered versions. Far greater speed than a Hurricane. Rudder and Elevator covered in Cotton, well, Irish Linen. No counter balanced Trim Tabs.
Interesting it needed that on the Hurricane[/quote]

"I'd rather fight in a Spitfire but fly in a Hurricane," said Ginger Lacey.

The Hurricane was better regarded by some fighter pilots who flew both, as it could take more damage and was a better gun platform. This may have been borne out by the contribution of the type during the Battle of Britain.

The Hurricane started production before the Spitfire and was easier to manufacture. During the Battle, the RAF fighter force was about 2/3 Hurricanes and 1/3 Spitfires.

No joke. When I worked on the Hurricane the first task was always translating the manual instructions from British into English.

Having owned a British sports car, I heartily concur.

There are certain things that show sheer ingenuity and there are certain other things that show...... that's how those things have always been done.

The Griffon Powered Spit we had, 2200 CID with 2035 Horsepower, originally used a Shotgun Breech Type Starter so the12 volt Electric system was grossly undersized. It only had to handle radios and a few electric solenoids for Air Systems. These included Air Operated Brakes, Flaps, Coolant Doors, Firing Weapons and shifting the Supercharger from Low to High Speed. Several of these used Electric Solenoids to port air pressure to these items. Operating them on the ground before engine start reminded me of riding the bus in my youth. Hiss, Bang, Hiss.
For the Griffon Spits there was a driveshaft off the rear of the engine that went to a Gearbox bolted on the firewall. That Gearbox had the Vacuum Pump, Air Compressor, Generator and Hydraulic Pump all on it along with an oil pump and reservoir.
Our Spit had been upgraded to 24V with an Electric Starter but retained what I recall as a 40 or 50 amp generator. We also put as large a Battery as could be fit.
