I'm confused. Catorce is making cases and you are doing duplicate efforts. I'm getting cold sweats just thinking about duplicating cases in CAD. Rough endeavor.

From the looks of your CAD model, are you going to cast or machine from billet?

I have spoken to Tommy in the past several times. I don't believe there is a duplication of effort, since he is trying to make a 2 liter case specifically for historic racing, which has its own requirements that are different from what I am doing (most popular sizes of cases, starting with the 3.6, but with modern features and other bits).

Tommy has to stick with what will be legal in his 2.0 liter class.

I don't really think there is an overlap and I wish him the very best.

The case project has been an intense, hideously expensive multi-year project for me, and it's not over. In fact, I just signed up to purchase yet another 300K machine, so I am well aware that you can make all the CAD drawings you want, but when you need to start making chips, cubic dollars are required. Lots of cubic dollars.

As to machining one from billet, consider that the HAAS UMC 750 we were using (5 axis) was barely adequate. I have to upgrade to the new UMC 1000, which so brand new its not even out yet (will be out Q1 2019).

The machinery required to do this is daunting to say the least.

And there is not even a suggestion of making my money back whatsoever.

Yes, Catorce, I think you are insane. I mean, really insane.

I can't see you ever being in the black. Not trying to discourage, but I know the realities.

You are going to be hero of epic proportions here once you are making big chips for good!

Realistically would have to sell 100+ cases to be in the black. I'm not saying it won't eventually happen, it's just that it seems so far away

I’m curious what you guys are doing for the castings. I know in pump manufacturing there’s been a big if not complete move from hand made wooden sand patterns for creating sand molds to 3D printed sand molds. This seems like it makes low volume casting much more cost effective.

^Not sure what Tommy is doing I can only speak for myself. My molds were made with a mold positive that was machined from a composite material, then a green sand mold was made from there. My molds are very high quality and expensive, supposedly good for 25,000 cases before they need refreshing.

I'm not sure there is a 3d printer big enough to print a case half, or at least there wasn't at the time. Still, a 5 axis machine making a mold positive out of composites is pretty much 3d printing, just removing material rather than adding it. Both achieve the same end result.

I don’t mean printing the case, just printing the sand mold. I’ve seen them more than large enough to print the case mold. I was in a shop a couple years ago that had just cast a Ferrari head from a mold they had printed.

Honestly I didn't get into that part with my tooling guys. They did lots of tooling for IPD and Edelbrock as well as other auto casting companies. So I just let them do what they do best.

Hello Cory.

We will machine it from billet as our productions numbers will be low.

Hello Adam.

Your right - there is no duplication of effort here - we are making the 2.2 liter case but in all new improved design and trying to incorporate years of experience from racing into these.

Our 2.2 liter cases will focus on racing and especially historic racing.

I know your 3.6 case has been an hideously expensive multi-year project and wish you the very best.

Thanks - Olsen911 - Tommy Olsen

Billet? Cool. What machine are you using? Just curious.

Tommy, Looks good, not sure if you are aware that CMW here in CA already has made a billet case. They just put them up for sale

993 Billet Engine Cases

Not cheap, but they are available; perhaps this is a shortcut for you.

What you want ideally is the 7R case. However, magnesium gets brittle with many heat cycles. Very hot heat cycles make it worse. That being said, the 7R cases are the strongest.
