Hawker Typhoon parts.

Again with a little more researching ive come to the conclusion that photo (A) is indeed from a Tempest V with the back up of the pilots notes from the Tempest V manual.

Would anyone know for sure whether the 3 types of Quadrants that Air Ministry had posted A, B and C were all Typhoon or like Air Ministry says (on post 148) Photo A could well be from a Tempest V, or was this Quadrant (A) also used on Typhoons?

A tough one to decide as there isnt to much to go by on the net maybe someone may have some images of Typhoon and Tempest cockpits showing the answer.

Thanks Gents… we try!
With regard to running some volts through it… I, for one, don’t fancy trying to poke 24 volts through any of these components.
We did experiment with an original 60amp fuse… and the filament actually glowed… so we’ll give that idea a miss!

Cracking piece of work there.

Nice! You should run some volts through it all for fun 🙂

So, who’s for a bit of wiring harness fun?
With the cockpit tube structure almost at the end of Phase One; time to start thinking about the cockpit panel wiring.
With the original rubber-covered wire and seventy-year old electrical components having a dubious electrical safety factor; it was decided to use PVC sleeved wire of comparable ratings; (even though, as a museum exhibit it would never have to carry any power); and would be for accurate cosmetic purposes only. The wire used came from a well-respected vintage and classic vehicle wiring supplier in Worcestershire..
The next fun item was that even though laying in the wire bundles in accordance with the A.P. was pretty straightforward; continuous lacing as used in modern(ish) looms was not an option as this method was not used in the WW2 era.
The method would be to secure the Harness wire bundles with equally-spaced, sealed Clove hitch knots.
So off we go…Two hundred-or-so clove hitches later; we have something approaching the original. Materials used were linen rib lacing cord; and “Impex” high-tack stick glue, (which dries clear,) is available from hobby shops, and really works. (Sh*t and Blanket spring most readily to mind.)
Anyway here is the Starboard Electrical Services Panel…

The Hawker Typhoon spare gun sight bulb holder is located on the central gun sight services panel
immediately below the reflector gun sight; and to the right of the gun sight dimmer switch.
This component; Manufacturers Reference: S.B.A.C. AS115; was fitted exclusively to the
Hawker Typhoon and Hawker Tempest V; and in spite of an extensive two-year search, has
proven to be unobtainable. Therefore; a replica component had to be fabricated.
Research proved that the bulb holder fitted to Rotax Type A, Navigation Lights;
(A/M Reference 5C/492) is identical to the three bulb holder bayonet receptacles moulded into
the original spare gun sight bulb holder, except for the navigation lamp receptacle mounting flange.

Given that; in the words of The Blue Peter kids programme…”Here’s one we made earlier…”

and here’s the original component…

Hi, It’s a very early photo of the next aeroplane and currently comprises of one frame, but as with the first Spitfire I made you have to start somewhere. [ATTACH=CONFIG]232398[/ATTACH]
Managed to find a photograph of my first Spitfire in the early stages of contruction. Plywood was used to make the frames.[ATTACH=CONFIG]232432[/ATTACH]

Hi Dylan,
Any photos ? sounds cracking what you are doing.

I’d love to make a full size static Typhoon replica to go with the Spitfire replica I’ve made. It would be great to make it and I am sure it would be a really enjoyable project. However if I was to make it I’d have to sell it and a second Spitfire would be easier to sell so that’s next. Maybe after that I can make and display a Typhoon assuming I can transport it easily.

And for my next trick…

We are now starting on the Blind Flying Panel. We were fortunate that the lower mounting bracket castings that attach the anti-vibration mounting assemblies to the cockpit forward cross-member… the one that supports the compass tray)… were still attached and in good condition. The top mounting is missing, and we have no idea… (after poring through the AP… including the repair illustrations)… as to its mounting position in the aircraft. It might be attached to the gun sight dimmer panel, but its shape, according to the AP… (We managed to identify it!)… seems to rule this out. Could it have been mounted on a bracket attached to the rear surface of the oil tank? The bracket itself is simple enough to fabricate; but any clues would be much appreciated.

We are also trying to source a Brass cap, Conical spring; Rubber Bobbin, and Aluminium retainer plate that
comprise the anti-vibration mount proper; (6A/617). We have two, but need a third, if any one has one going spare.

I have NOS springs for sale.

Years ago, when I had less sense and money, I had (note had) the top of one of the columns off an ex Portuguese Hurricane from Angels-one-five. It was AH2040 (mag alloy) with late crinkle covering and an electro pneumatic button.
The tops you have will be difficult to pin down – do they the AH numbers? After bead/walnut even the most corroded grip may give up enuff of the AH number to allow elimination between early meteor, Tempest, Typhoon and Hurri.

The other differences between the columns are ‘south’ of your bit. The elevator pick off lug is double pronged on a Tyffie/Tempest and single on a Hurri. The lower chain guard on a Hurri is bent and welded steel – the others have a much more elegant version. The Tempest and Tyffie had even lighter pitch forces than the hurricane – therefore it was possible to easily over stress the aircraft/accel stall. Hence they had an ugly tray with lead bob weight. Some Tempests had cockpit green columns.

I assume it’s a mod. done when there was a change of Sabre Mark, i.e. from IIA to IIB, then IIC? If so, then box c represents an early machine with operable lever, box B is from a machine where the lever has been locked in place by a fairly crude mod. and box A, shows the later mod., i.e. lever removed and gate plated over.

Actually, in my rush to post these last night, I failed to mention that box A is probably from a Tempest V. The lack of landing lamp lever at the rear of the box is the clue I think.

And thanks for the drawing, windhover, it all helps!

Any more thoughts on the Hurricane/Typhoon/Tempest columns, anyone?

What was the reason for the mixture controls being blanked off?

A rare sight…

Blimey, there’s a lot of Typhoon parts around tonight!

How about these three throttle boxes, each with its subtle differences?

It’s not often we get a chance to view stuff like this nowadays.

Typhoon control column.

Alan;
Here’s a Dunlop drawing I came across a few nights ago.
The spade grip part number is 26AF/31517 (The jpeg is not that clear at normal size.)
Hope this helps. (26AF refers to Hurricane/ Tempest spares Typhoons are 26BX.)

Next major cockpit equipment lump to tackle is the Rudder Bias and Tail Trim gearbox and wheels.
Fortunately, our example has an intact 10 inch Tail Trim wheel, which was also fitted to the Lancaster. These Aeroplastic A.S.102 wheels are rarely found intact. Turning the wheels transmits movement to two gear sprockets which, in turn operate chain drives to the respective control surfaces.
The Rudder Bias wheel operates a right-angled drive comprising a straight-cut bevel gear arrangement; the crown bevel gear driving the main shaft and the pinion driving the operating wheel.
The scale indicator arrows comprise a pair of curved blades; connected; and pivoting at their lower ends in a manner similar to a pair of engineering calipers. Each blade is fitted with a small spigot which runs in a pair of parallel machined discs attached to the respective Rudder Bias and Tail Trim shafts; each shaft disc being machined with a reducing concentric spiral channel. Thus; as the control wheels are turned on their shafts; the blade spigots slide in their respective channels, reducing or expanding the blade arcs of travel, and indicating their positions on the external scale plate by means of the right-angled arrow-headed ends of their respective blades.
All In all, it is a very sophisticated example of British engineering ingenuity.
Here are the before, stripped down and final restoration pics.

The legend plate is a tad moth-eaten, but we don’t’ have a spare… so, it will have to do for now!

Question for the experts…

Do the Hurricane, Typhoon and Tempest share the same control column assemblies?

I ask because these two columns have been in the garage (the garage that keeps on giving) for years and it’s time to sort them out.

They look like they would have had the electric gun button which rules out Hurricane, but are they from a Typhoon or Tempest and indeed, is it possible to tell the difference?

No easy clues on the spade grips due to corrosion, but they both have the same part number stamped on the column, which appears to be A73013.

Anyone got a Hawker Parts Book handy?
