I used to hydroform a lot of pipes.

It's easy if you follow these 2 steps. Ok, 3 steps


Don't form the pipe as 1 unit. Header to middle of diffuser as 1 piece, rest of diffuser to stinger as the rest. If you have a plane break use it to your advantage now. Mark plane break and or all your sections while laying out flat templates.

2) while under pressure, in stages of filling. .. beat the shit out of wrinkles with a steel hammer. When done it will look like a stamping. Can't even tell it was hydroformed. I once sent a hydroformed pipe to get stampings made. They called me up and said he couldn't make dies for me. I said why? He informed me they wouldn't copy other pipe builders stampings. I lol'ed told him it was hydroformed!

3) roll edges before welding seems

Frits... my bestest friend ever.

Can you comment on why dome looks so clean after running?

I deeply regret to hear that, Jonny. But cheer up, one day you too will find some better friends .
Oh, yes, your question about the clean piston dome. Well, it has been running on clean petrol instead of pre-mix, and it had an extremely thorough combustion. The exhaust gases are very clean too.

.
Even with the piston at BDC you would not notice that it is a Ryger engine...

Booody hell Frits, there goes a lot of thinking down the drain.

Guess we'd all better get the brains into overtime................................AGAIN

So why does a 4 stroke carbon up the top of piston? It's running clean petrol.

Not being argumentative, truly perplexed.

And I'm assuming you meant ex port on Ryger stays clean as well.

Thanks Frits. Your comments about percentage of std parts. Intriguing.

Eventually, and will always be relationship to combustion efficiency.

Your philosophies about the Ryger engine make it very tempting for me to react. Alas, I still am not allowed to. But I can't resist re-posting this picture:

I bet you wish that you could push that piston further down. But what would you see? Let me tell you: nothing out of the ordinary.

Thanks for the confirmation Frits about the porting arrangement. Looks like I get another tick, lol

Piston rings don't touch the bore when they have a nice slippery layer of 05/40W oil separating the two either.

Ordinary - or at least current convention for those power levels, is a triple exhaust port....The homologation papers state one exhaust port i understand....
So there's one point of difference which should be visible.

3) roll edges before welding seems

Are you saying roll the edges to do a butt weld rather than leave them upstanding and seam weld ?

I'll try that next time. May have to make up a former from MDF, bandsawn to shape and with a radiused edge.
Don't have a sheetmetal form roll - do have plenty of MDF....

[Frits Overmars]

Well spotted Grumph. Insiders might notice the absence of auxiliary exhaust ports. But then again, there is no current convention for Ryger power levels yet...

[F5 Dave]

Dont need aux ports when there's no rings . . oh, um. . .

Nothing out of the ordinary!! eleven transfer ducts and ports might arouse some curiosity .... ... 11 ???? ...

Only you will not see half of them at BDC. Rob

Frits I think has previously gave a pretty big hint here, as to why the Ryger is able to rev so high.
