My multi spiral concept.

[G33k]

Have you considered running this in the opposite direction? So you spray water in from the sides and have it coming out the center. I would imagine you'd probably get soma amazing turbulence in the center and you could use a pin that reached higher from the center too. Whatcha reckon?

Sure is something to try, if I manage to build this...

I guess this never happened?


I had pretty much the same Idea...darn....

Anyways, I want to get a foundry setup and hopefully I can cast a few of something like this. What is the latest design that you would recomend?

Didn't someone mill something like this out of aluminium a while back? If I remember correctly, it wasn't spiral shaped, but it had straight channels from the center to the border... But I guess that technique could be used to mill those spirals too...

I work at a company who's business is machining plastic. Our mill can hold +/- .005" on nylon, and less on aluminum. More specialized shops should be able to hold +/- .003" on metals very easily.

Yes, I will eat crow. .003" is easily acheived on good mills. I was a 0 off. Learned alot since then.
