I don't know if this is helpful because my coomber's is not an "elmers" but rather a Tubal Cain so design isn't the same. Pictures of my coomber' are posted somewhere on here. My comment is last I was playing with the engine, I could not get it to run on air, but ran fine on steam. Leaks...

I've only run my triple on steam. Never could get it to run on air. Takes me a long time to get it going using about 20 psi. Before the condenser gauge quit, it actually registered 15" of Hg when running cooling water. Mine only runs well in one direction no matter how many hours I've spent...

Hi Henry An S50 needs very little steam. That was my first engine. I went very rudimentary for a boiler. I took a 2" sch 40 pipe nipple and two screwed ductile iron pipe caps. Good for hundreds of psi and the iron caps can be drilled and tapped. Put this in a piece of 4" steel tubing for a...

Not sure what your size requirements are but another source of a motor is a scraped motor from a high efficiency washing machine. Until I repaired my LG washer, I'd never seen such a motor. Rotor has a ring of permanent magnets that mounts like a brake drum over these coils. Bigger though...

Steamedlou1 here. Not totally new. Was on a few years age with a bunch of posts on stuart triple and condenser build. Problem is I changed email and forgot password so no way to log in, so I had to re-register. I was steamedlou.

sorry didn't get the youtube link posted correctly http://www.youtube.com/watch?v=qLv4BqHcefk

sorry about that. posted the wring youtube link Here is the condenser test link http://www.youtube.com/watch?v=qLv4BqHcefkbe

Almost done. I completed the surface condenser and all that's left is piping and final mounting of the whole assembly. I was totally amazed. the surface condenser actually works and is not just for looks. I tested the engine running with and without cooling water flowing through the condenser...

Abby, Yes it's often frustrating looking for BA stuff in the USA. And sometimes the postage is ridiculous from the UK, often with a company charging way more for postage than the value of the item shipped. I have looked at maccmodels but I think I found a better source at least for those of us...

Here we go. Got the Stuart triple painted, polished and running on 25 psig steam. Now to get it mounted and finish the surface condenser. http://www.youtube.com/watch?v=gqGlvtVMilQ

abby. These are as close as it gets in small OD. In fact these are the only "small OD" washers Ive ever run into. I actually purchased these to use on an engine that was done with No 4 UNC screws. OD of a No 4 screw is .11". ID of these washers is .11". Its actually a No 3 washer that gives...

I am often looking for small washers to protect the paint surface under screws. The locations seem to always be where there is very little clearance around the screw head. McMaster Carr under their flat washer heading carries a line of military spec. washers identified as NAS620. Thes are SS...

thanks guys. actually i do have residual magnatism in poles. got it by attaching a very strong magnet to it and running it also. wiring should be correct. but dont know what i should expect from this design. There was nothing in instructions which indicated output. i will keep trying. for...

I've got the renovation of the Coomber rotary and the construction of the Gramme dynamo completed and mounted. Engine runs beautifully and flyball governor actually works but the dynamo only puts out roughly 10-12 millivolts. Oh well looks cute anyway.

xrad yes there are a few items of sloppy layout on this engine. He didnt heed the warnings about the carefull layout between the cylinder drilling vs the base. Ill do some cosmetics on that by enlarging the base casting with JB weld. Paint will hide that. I always find it interesting to...

Ok getting back to my Stuart triple. Beginning fabrication of a surface condenser. Not going for a very big one. 3 1/2" long , 1 1/4" copper body with 23-1/8" diameter tube bundle. Hit the auto parts store and used a pair of brass freeze plugs for tube sheets.

I can't believe it! Nothing I buy ever runs when I get it. This beast ran first time I tried and in both directions. Needed 40 psi steam to get it going and it stalls out at 25. Leaking a lot of steam at this point. I think when I get all the glands etc. tightened up it will run on a lower...

My new triple project arrived today. Its a beast! Didn't realize how big it is. I thought the Stuart triple was big weighing in at 11 pounds. this weighs 34. Makes the Stuart look like a wimp. I'm behind. haven't finished my Coomber rotary yet. These will keep me off the streets for a few...

Ok got a little video here after some adjustments. I'm totally amazed the fly ball governor actually works and will roughly maintain a speed while steam pressure is being varied from 25 to 50 psi. Works better than I would have ever expected. love it. http://www.youtube.com/watch?v=8CHjFLp2AVo

I phoned in an order day before yesterday and it arrived today. when I talked to them they did say they had been hacked and it was taking awhile to fix. lol wonder how many of our credit card numbers the hackers got?
