Bristol Engine Manifold (pg1 Pwr)

Here we have a carburettor manifold from a

Bristol Mercury or Pegasus.
It goes between the Hobson carb and supercharger

part number FB 60534 D9762

The Mercury's smaller size was aimed at fighter use, and it powered the Gloster Gauntlet and its successor, the Gloster Gladiator It was intended that the larger Pegasus would be for bombers, but as the power ratings of both engines rose the Mercury found itself being used in almost all roles. Perhaps its most famous use was in a twin-engine light bomber, the Bristol Blenheim.

Coffman Starter (pg1 pwr)

A Coffman starter fitted to a Spitfire

A number of methods have been devised to cause an internal combustion piston engine to turn over during the starting process, the most common being manual cranking and electric starter motors. Another method involves the use of a special cartridge that is generally similar to a firearm cartridge (minus the projectile, of course.) The Coffman cartridge system was one of the most common brands, entering the market in the mid-1930s; another was the Breeze cartridge system, which was produced under Coffman patents.

The cartridge starter offers advantages in certain situations, particularly in aircraft applications. For one thing, unlike the business of starting by manually spinning the propeller, a pilot can operate a cartridge starter single-handedly from within the cockpit. A disadvantage is that a supply of special cartridges must be carried, one for each attempt to start the engine.

RAF RCAF (MERLIN ENGINE) RADIATOR SHUTTER THERMO SWITCH (pg1 Pwr)

LANCASTER BOMBER MERLIN ENGINE RADIATOR SHUTTER THERMO SWITCH. THIS SWITCH WAS REMOVED FROM LANCASTER BOMBER FM 215 AS TIME EXPIRED OCT 26/1959.

Superb item with great provenance, connection to both Merlin and Lancaster. A very rare event is to have a picture of the actual aircraft a part has been removed from, the part was almost certainly in situ when this picture was taken of

Lancaster  FM 215.

History of Lancaster FM 215

TOS 21.8.45 in RCAF; was the 4th. Converted by Avro Canada to Mk.10P; issued to #408(P) Squadron with code 'MN215'; did extensive test on SHORAN; was used for short time at Winnipeg as a SAR aircraft with #111 Composite Unit about Aug. 1959; SOC 28.9.62

Oil Heater A/M 5A/2048

220 Volt oil heater. It has a nice A/M crown. I can only assume this is for preheating oil in big aero engines. Looks serviceable.

£25

 

Hobson Throttle Housing

This is a really nice Hobson throttle housing. Its in mint condition and a really nice display item. This belongs to a Mighty Centaurus engine which powered the awesome Hawker Tempest. Basically the piston aero engine developed to the Max. I believe the Centaurus developed over 3000 BHP and you can tell the amount of 100 Octane Petrol it needed by the size of this throttle housing. It contains a huge butterfly valve.

Spit Flips V1

 Pulse Jet Model(pg1 pwr)

Here we have a pulsejet engine, designed and built by one of my suppliers. Use to power the V1 flying Bomb, better know as the doodle bug. Shooting down one of these could prove extremely hazardous and a technique was developed to flip the V1 over using the fighters wing . The giro was destabilised and the bomb crashed.

  • Combustion chamber is from 2mm stainless steel
  • Valve plate to which the valve is attached is alloy
  • valve is from 0.005 in blue spring steel
  • Thrust tube chromed and painted (VHT) mild steel
  • Inlet venturi mild steel (VHT)
  • Fuel / gas jet alloy
  • Valve retaining bolt stainless
  • Fitted with conventional automotive spark plug
  • Overall length 780mm (30")
  • Total weight 800g

Starting is fairly straight forward.

It is extremely loud and so ear protection is recommended if you intend to run this model.

  1. Connect gas / fuel pipe to fuel jet pipe.
  2. Connect ignition source to spark plug.
  3. Start ignition (switched off after engine starts)
  4. Direct stream of air through front of engine
  5. Turn on fuel supply
  6. Once engine is running steadily (usually after 5 or 10 secs) turn off air and ignition.
  7.  The ignighter for starting the pulse jet is included.

As this unit is home made it is intended for display use only, if you run the engine you do so entirely at your own risk.

We will deliver in the mainland UK for the postage price quoted or you can collect. These engines will run on super unleaded petrol as they have hardened valves

Merlin/Meteor Engine(pg1 pwr)

Meteor engines are basically Merlin engines converted for tank use. They are not supercharged. They can have Merlin exhaust stubs bolted on and some people who have these mounted on trailers and run them at aviation events. They sound just the same as a Merlin .  Can be mounted on a trailer and run with a few ancillaries just add a fuel tank, "Large" these 27 litre monsters can consume a gallon of petrol a minute. You need an oil tank a radiator and off you go. Unlike the Merlin fitted to aircraft this engine will run happily without the need to apply a load. All the Merlin's you see for static running require some sort of cut down prop as they do not run well with a load. They are awesome, the first time one of these beasts fired up next to me I jumped out of my skin. Once you get used to it these engines have a presence they ooze roar power and sound just the same as a Merlin "sweet" to see our Meteor running click here

This particular engine is missing its starter motor but we will be able to find one for the purchaser.

Merlin Exhaust Stub (pg1 pwr)

This is an exhaust stub for a Merlin. Its in pretty poor condition due to corrosion but could make a nice display item and is relatively easy to restore to static condition with some metal filler and some patience. Not sure which aircraft I think more likely Mosquito or Lancaster than Spitfire which generally had shorter stubs.

£45

 

 

Merlin/Meteor Stubbs (pg1 power)

Brand new Spitfire exhaust stubs which fit Merlins or Meteors. We make these to order, delivery is five weeks and a 50% deposit is required. These stubs were made for my Spitfire project and as we have the jigs ready to go we are offering these at a fraction of the cost of the original set.  Complete SET of 12 stubs.

K Gass Priming Pump (pg1 pwr)

Mk XIV Griffon Powered Spitfire

A mint condition functioning K Gass primer. Situated in the Cockpit used for priming big Piston engines for starting. This type of K Gass was used on the later Generation of engines such as the Rolls Royce Griffon, a 36 Litre replacement for the Merlin. Also fitted in the Tempest and Sea Fury using Centaurus engines.  Basically anything with a Big Piston engine over 30 Ltrs.

This belongs in the instruments section as it is closely related to RPM indicator's listed in these pages.

RPM Counter drive(pg10 ins)

This is in superb boxed serviceable condition (subject to required check's and permits only opened for the picture and immediately resealed. These drives were connected to the Merlin by the normal direct drive cable that  powered the mechanical Rev counters .It generates an electric current and power's the electrical type RPM indicator. This  type of indicator was used where it was impractical to use direct drive cable's. They were used in all Mk's of Lancaster's and many other Bombers where the cockpit or engineers panel was far remote from the engine. It was actually used to power the RPM gauge in the rear cockpit of the very rare two seat Spitfire's. These do appear from time to time but never in this condition, this should end up on a flying aircraft.

Merlin Piston 1 (pg1 Pwr)

 

 The short Merlin piston was introduced sometime around the beginning of 1943 to combat skirt failures caused by cracking, it was found that this part of the piston was not needed and all subsequent engines had short pistons with the exception of the Meteor.
 Merlin are forged, looking inside the piston it is easy to tell Merlin and Meteor ones apart, as Meteors were cast.

Above and below  a correct piston for the Merlin XX which had had skirts

MK XX Merlin Piston 1 (pg1 Pwr)

Above a Merlin XX Note the skirted Pistons.

The Merlin XX which ran on 100 octane fuel. This allowed it to be run at higher manifold pressures, which were achieved by increasing the "boost" from the supercharger. The result was that the  engine delivered 1,300 hp (970 kW). Another improvement made to the XX and future Merlin variants was a redesign of the cooling system to work using a 70/30% water/glycol mix rather than the 100% glycol of the Merlin I, II and III series. This allowed the engines to run some 70 degrees cooler, substantially improving engine life and reliability. This also removed a potential fire hazard from Merlin powered aircraft, as pure ethylene-glycol is a flammable liquid
