No, I understand that. Was more wondering if you were planning to include one.

unless the rotors could realistically be done for less than $1k USD each then i doubt any of them are going to be huge sellers. it is great work though and the ability to make your own compression ratios is a plus.

for the amount of work involved and the equipment required.. i really wouldn't worry about it, i've given up much lesser secrets that just about anyone could do.

Thats the whole reason why I show this thread. To show that nothing is impossible.
But when it comes to the reason that I maybe will be produce and sell something, I would be stupid to show my solution

If that was my rotor you would see me holding the camera in the rotor face. I dont like places for carbon to live and build up.
Damn cool project tho, inspiring...I may sell all my earthly possessions, get some machines and start a 4 rotor cult somewhere in Wyoming.

i also like the idea of the compression ratio on the rotor, will be good for if you ever tear down the motor and forget something. the grenade idea is pretty clever too.
tagheim... would also like to note here that i've been following your project from day one and it never stops amazing me. love the determination you've got going to do all of this, very very brave endeavor.

i feel like if you got rid of the "swirly bits" in the text you should not have to worry about hot spots, because the heat should be dissipated through the rest of the face of the rotor. i would think that because of the depth that of the engraving and that the "edges" created by the numbers are approximately 90 degrees you should be fine.
the reason i make comment to the angle of the engraving is that the dish part on the face has similar angles and you would run into hot spots on those corners if it were to be an issue.
it seems like a hot spot would occur where a piece of metal (steel in this case) were to stick off of the surface of the rotor gathering heat faster, because it can absorb heat from more directions. and considering how shallow theses cuts are the thickness of the rotor face in this area is virtually unchanged. heat should dissipate just like it would without the engraving.
so long explanation short, if you get rid of the swirly design elements (i.e. make the decimal a regular circle, rather than a yin yang symbol). i dont see it creating an issue, but this is my opinion based on logic, so take it for what its worth. and anyone that sees a flaw in my logic please say so, i dont want my statement to be taken as gospel (unless im right, lol).
on another note the grenade idea is awesome, and you do have 2 more faces on that rotor, so you arent limited to just the comp ratio.

Now finally the production has begun for real ... I had never guessed that it would be so much preparation work on these. Do they look simple, but have been scratching my head once or three times ...
On top of all this, a revision of the CAM program take 5-15minutes of the heaviest pieces.
3st roughing 3D pockets from one direction is about 1500kb large program. Times the third Times two ...
Milling time, we will not even go into. It takes time

I would hate to machine that, don't you get troubles with removing the chips when milling those deep pockets?
Looks as awesome as always though.
I'm using older cast S4 n/a rotors, no way I'm going to try to fabricate a set of rotors without cnc equipment, that would be so difficult it makes my head hurt just thinking about it.
