If you make that center section the same width at the top area, you do not need those gussets.

I understand, we are just playing around with it

Scanning cases

pretty neat. theres a really good youtube video from erickson machine on 701 porting. he goes pretty in depth and even as a cutaway cylinder and shows you the weak points where they crack. its not actually on the base but up a little at the bottom of the water jacket where the casting is thin. he explains in the video.

ya i already found it. we are modeling the oem port surfaces first, then we will make revisions.

Cases and head are scanned, now on to modeling

Very cool, Im not sure its worth making a cylinder at all but cool fun to play with

We are going to machine a complete billet motor. We are modeling the stock cylinders just to have the data as a starting point. we will most likely be far from oem on the cyclinder we machine for IMTS2020

What company is this for if you don't mind me asking

 

[waxhead]

That will be awesome. Can’t wait to see it.

Your next project, to design a wet cooled jetski cylinder head to fit on a direct injection skidoo 2-stroke:

Edit: Dang! Storbeck you are correct below! The Rotax E-TEC is a water-cooled direct fuel injection, direct oil spray on crank bearings 2-stroke engine:

Is it advisable to adapt such an engine to standup jet skis?

I know a guy that will scan and machine every thing you want, real nice price, pm me for contact!

i dont want to name names but its or an American Cnc company that is not haas.

Why would you need to change the head? It's already a water cooled motor. Lots of other stuff would have to change, but I'm not seeing why the head would.

 

[Quinc]

I think he means cylinder.

 

[OCD Solutions]

Pretty cool process.

Now that you have the scanned files, would you consider making a complete lightweight motor out of a composite material for display purposes or builder mock ups?
That idea was in my head when I first built my CNC setup but it is hobby class and doesn't have anywhere near the capability required.

I think we can make that happen, we still have alot of actual modeling work to do though. We are hoping to have all modeling done by next week. We are sending out for quotes on stock tomorrow, hopefully getting approval to order stock next week as well.

Somebody could probably 3d print this pretty easy I would think.

I can print 500mm cubed so could do it easy
