Yes, well, not good enough for me.
And it turns out the same company ( www.plasticareinc.com ), and local store, DOES have a CNC machine.
So I ordered three more rotors; cut from 1/2" lexan instead of acrylic.
I ordered three because most of the cost is for set-up and just a little more for the extra materials.
Going to cost $100 for three precision rotors.

On a side note:
As I disassembled my 1/4" stator plates I discovered that a few of the 3m mounting tapes were not holding very well.
The rest were pretty solid but I do have a concern these mounting tapes are just not sufficient; especially since the rotor magnets are constantly pulling on them.
So the new, 1/2", stator plates will have the coils glued/welded directly to the plates.
Which will be stronger, safer, and not have any foam "cushion" or movement under the coils.

Guess I'll just have to fabricate new stator plates if I want to try a different coil configuration.

That is all for now.

Hi Scorch and all
Your rotor looks just like mine; the same laser cut not perfect vertical.

Hey Scorch

may be better to glue the coils to small thin plexy plates that can be then attached to the larger mounting plates. Its cheaper and easier if you have to make changes. Coil modules. ;]  Plastic/nylon screws/bolts from home depot or lowes to attach the modules.

Hi guys

I have removed the coil from the rotor and the rpm went higher than before. So the magnet was just neutralising the litlle drag produced by the core. I'm removing the video

Hi Scorch,
    I agree with mags, also we need to have an adjustable coil, so we can easily adjust the distance of each coil.

Hi all

I have seen in mr. R videos a type of bifilar coil that cancels eachother the output. But when adding a magnet behind the coil there is output. i have found a sweat spot that doesn't affect the rpm when the leds are lit. The coils in the video are using this principle but i'll make one for further experiments.
