Calculating top speed on ice...

The intakes are finished.

Very beautifull already,show a foto with your welds please.

Thanks Barry, here is a pic of a seam on one of the intakes. Nothing special but then it is difficult to get that "stacked coins" look on thin sheet metal.

I welded up the engine today, it looks straight to me and all of the tolerances are met.

Here are two pics of the starting grids, I should have taken the pics after I welded the intakes and grinded the inside smooth but you get the point anyway.

Only the fuel system and front engine mount left to make before I can fit her to the kick, hooray!

Sweet build

This engine looks quite a bit different from the previous one. More traditional

[Johansson]

Thanks. Here is a pic with the two of them beside each other that I took yesterday, not that much difference when looking at them from a distance but the new engine is completely redesigned so not a single part from the old Thinderchine can be found on it.

Ha! That's what I meant:

Thunderchine? That's not Thunderchine! Or is it something that ends with "two" (not minutes)?

Very nice build again! Looking forward to test results

Only just realised the encap is bolted on. Is there a reason for that? Also, is the combustion chamber stil a cone?

[Johansson]

Thanks guys! Before I tangle myself up any more in fussy explanations about the engine design which I don´t know enough about I ask you to sit tight and wait for a PM instead.

But yes, the combustor is slightly coned.

The end cap is there so I can get the preheat coil into and out of the engine, it is made from 2mm SS sheet so it will also be a good place to fit the front engine mount. I considered putting a flange on the combustor/transition cone joint as well but it felt like it would get so much heat that it might warp and leak so I settled with the end cap flange.

Really beautifull.....I see you weld with a TIG.
I have a MIG/MAG & need after a lot of grinding to make it smooth.But I do the grinding always after she runs good.
Can you make some pictures from the injectors,maybe it will help me with mine.And make also a video from the starting and running.

I haven´t given the injectors any thought yet, so I don´t know how they will look. Are you going to run your engine on propane?

Rest assured that I will post a video of the first test run!

Do it, you are almost there!


you know you wanna

[Johansson]

Boooring, doing it like this will be more fun!

(And yes, a friend and I have been discussing DIY cruise missiles lately. Hopefully our gouvernement would take it a bit less seriously than Bruce Simpsons did...)

O.k., doing it with your helmet on... alrighty.
But doing it while roasting your balls?? Strange guys those Nordish Swedians.


Ah! Perhaps all their women leave for warmer places during the harsh winter. That's why!!
