Ken, are you referring to the piece by Luc F on combustion and HCCI?

Not sure what I did wrong, but try this:

If it stuffs up, then go to pitlane and then "[2 stroke] And the one?" on the LHS rolling topics listing

A sort of a French Fletto

Look at that, a bit of good old fashioned patternmaking, good to see.

Yes Ken I like those examples too, it all sort of seems to be more achievable to me in the home workshop situation than all the hi tech stuff (not that there's anything wrong with that of course) ..........If only I could get my ass into gear again!

Little update from the kids corner.
Each fin took about 6 hours to print.

I love your surface table.

Did you mean each fin or each half pattern? (I'm not familiar with printers and how long they take).
Those attached risers you are using are huge!

Nice, good to see the junior helping. He'll be telling you how to do it in a few more years .

Now question time.

1. You posted this on P105 https://images.tapatalk-cdn.com/15/10...62e1a3f26d.jpg Was this a computer render or an actual pattern?
2. Have you gone to an SLA printer rather than the FDM?
3. Are the transfer & exh passage coreboxes you previously posted to be used in conjunction with this cylinder?

Otherwise excellent stuff.

I mean Each half fin. Its a "slow" process.
I tried a risky printing job to save time and work. But I lost the 48h job a 95%...

This is a older render.
I only work with my zortrax printer.
The previously posted corebox are for this cylinder, but I need to reprint them in case of layout changes.

Slider cylinder. Still waiting on the cylinder machining, so chucked it on a go kart to see how it might fit. Note that this is not the actual kart we might use (assuming the thing is a goer), but it gives some idea of the packaging issues. 2 options wrt the cylinder orientation:
1. Two exhaust outlets forward. If we go this way, it'll mean a tight bend of the exhaust header adjacent to the seat, but the other two exhausts are not too bad, with just lesser bends in the headers.
2. One exh forward. Possibly means bends in the divergent cone and possible carburettor/airbox clash issues.
As the thing is bi, it can easily be turned either way. I think I can hold off making this call until the thing is a bit more complete.

Either way round you're going to have to call it the Tall Boy...

I can't remember, do CIK regs say the pipe must finish behind the seat ?

With that ex you should call it the Woody
