Re: Vacuum Ejector Drawing / Guidance

Many thanks Julian,
I'll try the ejector cone modifications as you suggest - it's great to hear that you have had good success after modifying the design.
Like you, I'd used an injector steam cone inlet reamer to make the ejector steam cone entry.
Best regards
Steve

Re: Vacuum Ejector Drawing / Guidance

Drawings received and printed - many thanks Fred. I'll make up one of each and see how they compare on air on the bench. I'd hoped for a bit more suck than the 17" I'm currently getting. Keith Wilson's original article suggested that the ejector would pull 20" at 40psi but it's quite possible that t...

Re: Vacuum Ejector Drawing / Guidance

Thanks Fred, the drawings would be much appreciated. I'll PM you with my Email if that's okay.
Do you recall what vacuum you've achieved with yours?
Best regards

Vacuum Ejector Drawing / Guidance

Hi there, Does anyone have a drawing or sketch of a vacuum ejector that they've built and found to be successful? I'm aiming for 20" Hg at 60psi. Testing mine on air this weekend, built to a Keith Wilson drawing from a 1980's Model Engineer, it pulls to 17" Hg at 80psi but only 8" at 60psi. The ejec...

Re: Utility Trailer

rkcarguy: The tarpaulin bows are made from standard 3/4" schedule 40 pvc pipe and fittings. The uprights and horizontal cross-pieces were made and installed initially (see first picture). The approx. 20 degree bend at each end of the curved portion was formed by holding the piece in a vice, softenin...

Re: Utility Trailer

Everything's arranged to give a little over 10% of the total weight on the tongue Ed. When laying things out I used a scale on the tongue in order to determine where everything needs to go fore-and-aft. For clarity, the Erickson chocks are not movable they're bolted down to the trailer frame. I roll...

Utility Trailer

Hi all, Taking the engine to the NJLS this weekend there seemed to be a fair bit of interest in my utility trailer setup. I've attached some pictures should this help anyone out or give some ideas. The trailer is a 6 x 10ft aluminum utility trailer from Legend Trailers with home-built modifications ...

Re: Coal purchase

Hi there, I went through a similar thing a couple of years ago - an engine that would steam happily on Welsh bituminous coal simply could not cope with US anthracite rocks (see thread "Coal Issues"). As others have said, anthracite requires a lot more heat and air to ignite and a continuous draft to...

Re: Spark arrester design

Hi Glenn, I haven’t yet steamed the Hunslet, but the in-smokebox spark arrestor arrangement is nothing new and I make no claim to its originality. Hopefully all will be well so wish me luck! The mesh is 316 stainless with about 1/8” holes, this was based on generally consistent conclusions from seve...

Re: Spark arrester design

Hello Glenn, If you are looking for a top-of-stack spark arrestor then you may want to consider the following design rather than a mesh: Spark Arrestor.JPG Although more difficult to retrofit, an in-smokebox design is obviously less obtrusive. Stainless steel mesh is readily available, for example M...
