CLaNZeR:Quick Movie showing my Stator Mounts.
< http://www.overunity.org.uk/ocpm/CLaNZeRSStatorBearing.wmv >

Have you tried the cube-magnet stator I suggested? I see some interaction between stator and rotor, so there must be something ferromagneic in that stator, right? Or did you just give it the finger to get it spinning?

@RB: you might be able to find some plastic tubes, like at the hobby shop or the garden store or the hardware store, that has an exact or close to 1/2 inch ID. Then you could just use some kind of improvised spacer to go between the magnet and the bearing, inside the bit of tube. This would almost duplicate my Delrin holders but without requiring machining.

Also most drills will drill Delrin and Nylon slightly undersize. So if you can find some solid Delrin rod (the best) you could simply drill it out with a 1/2 inch drill bit, and it probably would be enough undersize to provide the correct tight fit.

Your device is taking shape and looking good! Just one thing, I noticed some heat damage from the tooling in some of the pieces. If you use WD-40 as a cutting lube in acrylic you will get much nicer looking cuts, with less chipping and melting. Just wash it off with soap and water when you're done. Voila!

The Video just shows a slight push of the Rotor with my hand, just to show the interactions of the Rotor Magnets with the Stator magnets.

I will wait for the correct Stator magnets to arrive before serious playing, this is just progress blog on my build as such.
I managed to also source some Rod magnets , but 5mm instead of 6mm, but will give them a go.

I replied too your emails mate regards the Cube stator magnets asking about sizes first thing this morning, but your Spam Filter is probably still checking me in the Bulk emails folder hehe :)

Thanks AL

Must admit most times I always Cut dry Polycarbonate and many a person gasps at me. I tend to put up with the odd scarring and any holes I need dead accurate I mill smaller and drill with exact drill size after on the press drill.

I am lazy and cannot be assed to clean off WD40 with thinners after hehehe

I could slow the cutting speed down a little maybe though :)

I tend to use lube with alluminium though, Honest!!

I don't know. Haven't had that email account up this morning. Been too busy with work-related stuff today. Got a break for a couple hours, then I have to get my nose back to the grindstone. Right now I'm gonna go get my first meal of the day. When I'm done eating, I'll check my mail.

Actually, I prefer posting here in the open whenever possible. Email is for work and it's a completely different email than I use for these communications.

Do not worry mate, if anyone is open to posting stuff public, it is me, I am sure I have proved that by now over the years!!!!
Well unless asked not too of course LOL

For those that haven't seen them, there are a number of documents and drawings appearing on overunity.com.

Here's a link to one that might be of particular interest:

OC that's great, thanks for sharing. May I also suggest we link this to the ocpmm website that Patifier is doing.

Wow! That looks like something I could build!
That's a really good job, Jason.
I see you even put the thread fit class in.
The only thing I would add or change is the rotor axle. I know it's what I showed in most of the pictures. But if you look at the later ones, you will see a 3.5 mm shaft instead of the 1/4-20 brass screw, and the 1/2 in hole in the rotor has been "plugged" with a Delrin insert to adapt to this shaft. The shaft is mounted in a dual ball bearing holder with a spring compression end-play eliminator, and the holder in turn is mounted on the base, in lieu of the brass screw. The rotor now simply slides on and off the shaft. For upside down runs I secure the rotor with a little retaining collar with a setscrew.

It's nice to see a real engineering drawing for a change. I usually just sketch stuff on napkins, and that makes it hard to see those leftover bits of food that are so tasty in the middle of the night.

Try storing those bits in your beard, like Desertphile.

Some more replication photos. Seems like everybody is still waiting for magnets.

Well I just scavenged six more hard drives from the I.T. repair department. Got modern ones now so I expect the bearings to be quieter and smoother when I get them apart.

Someone should let the person over at overunity.com in the first two photos know that the lower left stator magnet holder needs to go over to the left one more hole.

FYI all: Due to a bad case of 'replication envy', that I seem to have caught...
..My 'fan bushing set-up thing' has been tossed into my scrap box.

I've ordered magnets, found a local supplier for small bearings [R/C hobby shop nearby..thanks to whoever suggested a 'hobby shop' as a source back in July], and determined that I have enough tools, materials and skill to attempt a 'proper' replication.

I'm 'way behind' some of you [build progress]..so any and all results positive and/or negative would be greatly appreciated....Thanks All...GREAT STUFF IS HAPPENING HERE!!
