The engine looks great! I'm really looking forward to seeing it in the metal at Forncett.

Thanks for all the kind comments, It was great fun making this engine and also being involved in a small way with the restoration, Also thanks to Clare ,my satnav and photography buddy for putting up with all my questions and comments about modern IT stuff !!. The next project may be the Elephant boiler and the Corn grinding 'Hurst' to go with it. I am also exploring the possibility of making the stand for the model with the scale bricks that one can purchase.... The next beam engine i would like to make is the Woolf compound by J.E.Hall that is ensconced in the Science museum... Also i would like to make one of the engines that was in the local sewage pumping station here in Norridge The only item remaining in the BLDG is one of the spiral staircases !!...There is one photo and lots of drawings in the local archives for these engines. So we shall see...........

Beeleigh Mill model working under steam

So the engine is now working under steam after more adjustments here and there,! one of the advantages with steam is that you can see where the leaks are. So more tidying up and assembling the condenser and air pump. The governor also needs connecting up and unfortunately i have lost one of the bevel gears so it won't be revolving,  And just a week to go for Forncett...........

Hi Willy, a beautiful job and great to see it running on steam, just as it should.

How slow can it run?  When one sees videos of restored beam engines the beams have a very "majestic" motion.  It would be nice to see this model running at about half the speed in your video.

Hi Kvom ,yes i know what you mean  , I shall try and see how slow it could go, at the moment it is between 60 and 80 rpm........ :thinking: It might need a heavier flywheel to keep the momentum though. I could mill out the rear of said flywheel and fill it with lead !!

On the twin beam engine I did, the way I got it to run slower was to fit a needle valve in the steam line close to the cyklinders and adjust the speed with that rather than changing the flow back at the boiler or compressor with the pressure regulator. That way it had higher pressure but lower flow at the cylinder, and would let me dial the speed down a lot more. At least, thats the explanation I wound up with, it did work though. That one had a small light flywheel, which at the low speeds was pretty much irrelevant. That was on a twin cylinder with 90 degree offset cranks, so no dead spots to have to carry through on. In your engine, the heavier flywheel would help with that.

Hi Chris ,i do have a needle valve on the inlet to the steam jacket so that might have the effect of wiredrawing the steam to slow it down ???????

Quite possible, it worked on mine, but that one is not a compound like yours. If it's already there, worth a try! At worst, you get to steam it up and watch it go again, which is always fun anyway.   ^-^

Well ,i have managed to slow it down but the needle valve is a bit tricky to get exactly right !! cleaning up some of the parts ...the beam bearings have square bolts just one per stud and they are just adjusted and then have a plate filed to keep them from turning. The weight of the beam and sweep rod and pistons keeps it from needing too much pressure to keep it in place.
