Whats the cost of the materials for this project at so far? Id imagine one of those gigantic metal discs costs an arm and a leg.

Tegheim · 01-05-2012, 06:58 AM

Actually each rotor-material costs 750SEK, and that is $90-100.
Quite cheep I think, as the HM-endmill of 10mm dia that I use for the pockets costs about the same

Tegheim · 01-08-2012, 08:00 AM

Built me an lightweight-engine today that is alot easier to get in and out of the car when i want to do some measurements

Sweet... how much power is that bad boy making? Biggest problem you'll have with that engine is termites...

Tegheim · 01-27-2012, 03:21 PM

A good start... at the end...?

I think you're on to something here as far as selling rotors if you needed to.

Wow really? Thats awesome dude its probably cause you know people lol I bet if I tried to buy that it would be more than 100 bucks.

Tegheim · 01-28-2012, 04:11 AM

No, the materials aren't the expensive. The expensive is the time in the machine.
If I would hire myself at work, my boss would charge about 1200SEK/hour, thats about 170USD/Hour...

About how many hours of labor are involved in making one of your rotors? Out of curiosity, I checked what rotors cost at Mazdatrix. A new rotor from the Mazda factory for an FD costs about $700 US dollars; you can get one a little cheaper shopping different Mazda parts dealers, but that's a good reference number. If you & your boss can get the unit cost per rotor below that figure, you might have a great business opportunity here.

Tegheim · 02-12-2012, 11:52 AM

I don't know much hours involved, but theres a couple...
Mostly because the machine I'm working in aren't high-speed-machine.
I'm limited to 4000rpm in the spindle.

Today I worked in the wrong direction

If it all works out like you plan and it can take a beating, you should start to produce 2 and 3 rotor engines for the consumer market.

I would gladly shell out the cash for one!
