Looking good so far. I see you have gone for more of a composite build up of the displacement cylinder. I went machined mine from a chunk of solid, but either way should work fine. One think you need to make sure of is that you eliminate ANY gas leakages as even the smallest will kill...

Thanks! Needs to be very smooth to run at all, but once everything is just in the right position to avoid any interference it will run pretty fast on a very low flame. A satisfying build and end product!

Hi Andrew I think the displacer piston was made from 6082T6 Aluminium bought from 1st Choice Metals. The power piston is a good quality fine graphite rod supplier from Jerry Howell. A bit expensive to get it shipped over with the bearings, but I figured it was worth it to ensure the quality...

Thanks!

Hi Andrew, Thanks! Yes I like the Jerry Howell plans and approach too. This is my first build from them, but have also purchased the plans for the Vickie Stirling Engine as that looks like another nice display piece. I am following your V-twin build on YouTube and have enjoyed your YT...

Thanks!

And here is the fan running!

Here are a few assembly pics....

Here are all the pieces before final assembly.

I have spent a few months working on my Jerry Howell Super Sterling Engine Fan and I have finally got it running smoothly! Very pleased with how it is turned out in the end. There is so little energy produced by these engines, getting the tolerances and friction reduction right is absolutely...

Hi Mike, having recently built this engine I've just had a look in the workshop and found the cutter that I used. In the end I went for a pretty sturdy and solid parting blade rather than using an insert cutter. I shaped the edges to give the stress relieving corner radii and then created the...

And here a link to a Youtube clip of my fully finished Kiwi!

I found a nice piece of thick off-cut walnut for the base of my Kiwi. I got it from a local specialist hardwood supplier in West London that supplies materials to bespoke furniture makers. I was able to mill out some neat enclosures for the Minimag ignition and battery to keep everything neat...

I decided to spend some time making a good quality stand for my Kiwi and ended up getting a bit carried away! The engine is quite tall and so I designed a quite high fuel tank based on some other examples I had seen online. I also designed and built a compact fuel tap around a couple of small...

Lots of great input there, so thanks very much from everyone. And also some great pictures of finished engines and display bases for me to aspire to! Thanks again! Richard.

Hi there I am n the final stages of completing an ETW Kiwi Mk2 and a planning how to mount it on a wooden base. It won’t be run that often but I do want to be able to run the engine as and when without petrol or oil staining or attacking the finish on the wood. Does anyone have good...

Thanks! Interesting idea about the circulating oil system, I might have to try that! Re your comment on the needle valve, did you mean in the float chamber? The steel needle adjustment into the actual carb seems to work fine. Richard

Thanks Vince! I feel like I've been following in your footsteps! Time to start thinking about the next project... Richard

Delighted to say that I've pretty much finished the Kiwi Mark II and it is a runner! The thin-walled aluminium float seems to work well and maintains a steady level of fuel in the float chamber. I went with the ignition points casting that was supplied although I had to fettle it quite a bit to...
