Glad you approve of the thermo jar

I built another but this ones slightly more technical. ill post pics soon but it needs more sealing too run. it pulsed 3 times very softly

thanks joe 8) those dims will be very helpful, hopefully i can get on to it soon! meanwhile, i have been playing with some jars and other things. today i built a thermo-jam which i run on methylated spirits http://www.youtube.com/watch?v=ypH1VfNYlrQ&list=UUjO_jDS27GY3r9xYDFkEDkw&index=1&feature=plcp...

Sorry I can't help with starting problems! But I do know that you can buy pipework, to join multiple bottles together, for caravans! Another option would be to use brake line tee piece from a car. The using s flaring tool you can flare and screw your brake lines together from each bottle. Join the c...

Awesome mate

Good luck with it, its a beast for sure! Looking forward to the videos. Remember your ear protection

Oh and I came up with a decent plan for throttle, I need to spend time researching because Iam not sure what to buy. But I think that if i only open the bottle tap enough to supply enough fuel for full throttle. Instead of 100% open. I should gain marginally finer control at the ball valve. I want a...

I had a go at making a Larry spec stinger. https://lh3.googleusercontent.com/-Z0Vdu5GLMzY/TwNbRhgp--I/AAAAAAAABHQ/YdcgXhQt350/s400/IMAG0481.jpg https://lh5.googleusercontent.com/-s7nyD7iSfb0/TwNbpFgVdiI/AAAAAAAABHg/JzHUOBp3aCI/s400/IMAG0484.jpg The head could be a restriction in the intake, its quit...

Yes thats the one. Might try just slicing 20mm of the CC length, and crimping the injector a little more. Propane is a thick gas and it takes a "shredding" effect to have it mix with air. The large CCs dont need as much because they cycle slower and there is more time/volume for mixing. The smaller...

The injector is just a rosscojector that has been opened up a little too flow abit better, ill crimp it tighter again and have another try. the first engine i built needs to have a fully open ended pipe with no crimping or squashing of any kind. it wont really start up without maximum flow. i have c...

Looking good, have some earplugs handy. Ball valves can be a little touchy, can't wait for the video. Thanks Joe, i do have lots of ear plugs haha. by touchy do you mean, not very precise! all or nothing! Looks like its running rich for some reason. Intake to tail diameter ratio is at 0.791, probab...

Thanks Joe

It may take me a few weeks to start on something new. iam still fiddling with the first couple pjs

so sad!

sorry for your loss.

Built another. https://lh6.googleusercontent.com/-MwyMJkj2ZbA/TvSrX3DqHfI/AAAAAAAABDk/JzA59ZC6csQ/s400/IMAG0455.jpg https://lh5.googleusercontent.com/-8ygnA5w-bmY/TvSrkqOiO1I/AAAAAAAABDs/YuBKJCo2MNc/s400/IMAG0456.jpg I bought a ball valve for fuel control. It needed some adapting to work with my set...

The specs of it are as follows

Cc 91mm id x 175mm with random cone
Exhaust 48mm x 960mm
Inlet 38mm x 128mm with flare

This is also made from random ugly scrap out of the skip at work :) https://lh4.googleusercontent.com/-4x5pcBlUK28/TvD8BlMlkeI/AAAAAAAABCs/23JImSBSPPE/s400/IMAG0448.jpg https://lh5.googleusercontent.com/-QlRsC3OWEmc/TvD8M7QxaxI/AAAAAAAABC0/O-SPsxTam1Y/s400/IMAG0449.jpg https://lh4.googleusercontent....
