Jerry's dual rotor stator

[Jerry]

Seems like this littel project is taking along time? I hope this works. I thought I read in a post or story by DanB about coating the stator form with crayon.

So thats what I did. Prety thick I might add. I made 2 13" diameter discs of 3/4" MDF.

I drilled the apropriet holes. One in the center and 8 around the outside. The hole in the center is 1/4". The holes around the outside are a loose fit for a #10 machine screw.

This is the coil form botton section resting on the bottom MDF.

Here are the coils in place with top section of coil form and wire between wafers.

Another shot.

All ready for reson to be poured.

Here top MDF is screwed down tight. I will let it set till tommorow then try to take the lid off.

Thats it for now. Getting a littel closer to testing. YIPY"

Jerry,

your picture stories are very good.

Thank you a lot for these.

My good Friend Taisto Suihkonen has used

a quite similar method to make the stator.

But he has used industrial formica

to cut the stator base.

   Very nice Jerry,

    In the future you might want to try Plane old paste car wax -- three coats works well, but let it set about 4 hours, between coats !

Another excellent mold release , is called PVA -- Poly vinyl alcohol -- available at boat supply dealers, that carry fibreglass products -- it is sprayed on, with a  spray gun then allowed to dry, forming a thin green film -- impervious to polyester and epoxy resin, but will wash off, with water !!

Really works good !!

    Enjoying your posts, and want to see that finished product !!   Bill H.....

Lowes sells a spray can of teflon for around $4 , havnt tried it yet , but i would imagine that it would work well also.

spray it on , let it dry ,and i cant imagine anything sticking to it.

Hi Guys.

I should have waited and read these posts first. In the Lowes dual rotor (1 year ago) I used seran wrap. It worked fairly well. Just had a littel of that stuck but I cleaned up the best I could.

A few problems this time. I don't think I mixed th reson long or thurough enough.

Some of it was still a littel slimy after 24 hrs. And the crayola didn't totaly release well in a few small spots.

I worked at it and I did manage to get it apart. But the crayola stuff made it look prety ugly. I don't think it will hurt this rotor though.

Well thats how you learn to do stuff. Trial and error. This time was the traial and error for sure but not all is lost. It will still work the same and the next one will be better I hope. LOL?

Heres a few pix. You may gigel? I do like the sugjestions. Thanks guys.

Jerry, you might also try pouring hi-temp candle wax into the mold.  Be sure to add release powder to it, and it'll pop free super easy. Nice part here is that it will stay in the mold, just heat up in an oven (if it's a gas oven, turn it to 350degrees for 10 minutes, then turn OFF before putting your mold in there.

My favorite reason for using it for casting items is that you can use a heat gun and paper towels to remove any wax that stayed stuck, and it's translucent white...
