Sounds familiar, I managed to scrap my first attempt at this boiler for similar reasons, fortunately at an early stage. My solution was more heat (Sievert 2942 burner or cyclone as appropriate) and insulation of the areas where heat was not required with vermiculite board.
I...

Thanks for the interest.
I used Cupalloys 424 (24% silver - melting point 740/800 C) for the firebox, and 455 (55% silver - melting point 630/650 C) for just about everything else.
In terms of the stay design this one is the belt and braces version. I used threaded bronze stay...
Its been a while since Inky Engines posted a new build. After building a third of Elmer Verburg's 48 engines over 2 years I made the decision to try my hand at the 1" scale 'Minnie' traction engine as described by L C Mason.
Progress has been slow for a number of reasons, not least the...

Good news - the engine is one of Elmer's designs, all of which are available for free download at www.john-tom.com/html/SteamPlans.html

This is a resurrected thread - I completed Elmer's Geared late 2012. I'm not building Elmer's engines at the moment...

Another work of art in the making, and as always superbly documented.
I'm not building Elmer's engines at present (distracted by a Minnie traction engine), but I'm still watching those who are!
Kind regards

This has turned out to be a really nice looking engine - it just needs fastening down and firing up! Its been impressive seeing you overcome all the little problems along the way.
Fancy was one of my first of Elmer's engines and I decided to make the column from a piece of stainless - I...
I for one will be watching this build with interest - this was on my to do list until I got distracted by a traction engine.
I've only seen one previous build 'based on' Elmer's #12 - one thing's for sure these things can really fly! Good luck.
Kind regards

I've followed this build throughout - very impressive. I particularly like the 'unique' flywheel design, and the engine's superb slow running capability.
Kind regards

Thank you all for the feedback, as always greatly appreciated.
I've still not firmly decided on the next project. I attempted to take a photograph of all the Elmer's yesterday, and it really is difficult now to get them sensibly in the same frame - also my wife has suffered all the models...
Just finished this one - the 15th of Elmer's Engines to be completed here at Inky Engines - this one took a little longer than most of the previous builds.
I gave up early any hopes of emulating Stan Shire's build in the glamour and innovation stakes! This one therefore I consider to be an...

1.5mm (or 1/16") Slot Drills are readily available (in the UK at least), surprisingly robust, and certainly well worth their small cost if you intend to build more of Elmer's engines. I use mine not only for the valves but also for Elmer's many fork slots - although a slitting saw could...

Congratulations on a very nice looking Elmer's Grasshopper - I'd love to see it running - as you say there is not much wrong with the build if it runs on 3 psi - my aim with these Elmer engines is 'breath power', but its only occasionally achieved. I haven't tried O rings to seal...
