|Thread: Looking for Mr M. E. Robinson|
Brian, I have sent you a PM
|Thread: Cylinder mounting.|
When building my D&NY I drilled and tapped right through the plates and used studs never had a problem with this method over the years I ran the engine.
|Thread: Mystery Tool|
It looks like a very old saw setting tool..
|Thread: Waterproof cabinet / box?|
I don't know what size your rotary converter is but this item may do Link it seems to have air vents in door.
|Thread: The Web Model Fitting Co|
From my model boating days I came across a 1966 Web Model Fitting Co catalogue mainly model boat fittings this company is no longer trading but it had some nice Oscillating steam engines listed, has any one on the forum seen any of these engines over the years.
|Thread: Running problems!|
I have a light spring on my Centaur disc valve and it gives even running, my theory is if the spring is to strong the engine suction will struggle to lift the valve and give intermittent fuel supply, if you watch the disc valve spindle which protrudes through the throttle lever arm you should see the spindle moving up and down as the valve opens and closes with a nice even movement.
My fuel needle is only open about half a turn when running, and I have full throttle range, having said that it is all down to good luck on my part as I am no expert on engine management.

|Thread: Beware new engine project!|
So now we know thanks to AJW, that if you build a Centaur you will be getting a known faulty Cylinder Head casting from the casting supplier, a good reason to haggle for a discount on that item, or ask the supplier to rectify the problem before sending out.
I built the Centaur and rectified the fault on the head casting which I thought had been dropped, at the time I didn't know it was a casting fault.
|Thread: Centaur crank lubrication|
Alan, If you haven't already seen the full article for the mods see Here
Hi Alan, The Centaur mods are from a article in Model Engineer 19th November 1976, Volume 142 No 3549 and titled Experiences With The Centaur By R.R.May.
My conrod oiler has a screwed cap, as photo. Michael.
There is a modification for the banjo oil feed, I also fitted a oiler to the conrod bearing, not sure why your piston rings are moving.
|Thread: Can opener - the holy grail in engineering?|
This one in the picture served me well during my National Service very simple to use but no good for arthritic fingers, it cut the lid from the inside.
|Thread: Piston ring gap|
I gave the rings on my Centaur a gap of 0.002 the engine runs well with this gap. Mike.
|Thread: Model gearwheel pump|
I made a similar gear pump for circulating cooling water on my Centaur gas engine, it has 1.5 mod x 12 tooth stainless steel gears, driven pulley dia 3/4 " free pulley dia 1/2", The pump body size 1 1/4" wide, 2" high, 1" deep.
|Thread: Mystery object|
Looks something like these Link
|Thread: Potting Adhesives : for Glass Fiber/Fibre Optic Bundles|
MichaelG, I have no knowledge of the subject you are working with but would this item be of use or what you are looking for.Link Mike.
|Thread: Bending cast gunmetal|
I had the same problem with my Centaur cylinder head, I straightened the lug cold with no problem.
|Thread: A gas engine question|
The engine gets hot which heats up the circulating water in the tank, it really could do with a radiator or screen cooler to dissipate the water heat, I have now fitted a gear water pump driven from the side shaft, but it still could do with a cooling system for prolonged running, the water tank is a Bean Tin.
|Thread: Another gas engine question, sorry!|

|Thread: A gas engine question|
Alan, I built a Centaur the cylinder head is machined as drawing but I made the conrod to bring the piston flush with the end of the liner, I haven't a clue what the compression ratio is but the engine seems to run OK, well for me it does.
|Thread: 2"durham and north yorkshire|
Another thought if air pressure is going into the cylinder steam cavity via the annulus, apart from the possibility of a loose or missing exhaust blanking plug, is the blower take off valve open or faulty as it takes it feed from this steam cavity. Mike.
