Acetone is ideal for epoxy removal.

Extra Hold Hair Spray works terrific for an epoxy release agent and is very cheap.

That spray might or might not work depending on the sort of epoxy used. There are chemical separators available that are made specifically for use with various epoxy compounds. And they're cheap too.

If you use an epoxy, make sure you use some sort of "release" compound on the guide posts or you will never get the stator out of the jig after the epoxy hardens. - Peter

Thanks Peter,
Those are some very good suggestions

Epoxy and Clamps

Thanks lighty
I will try that on some spare plates

Jetijs,

Remember that your last stator ended up being glued slightly out of alignment. So, it is very important to glue the stator pieces together exactly right.

I recommend that you build a jig to hold all of the pieces between two flat plates of steel or thick aluminum. Mount four guide posts to the bottom plate so they go through the mount holes of the stator pieces with very little clearance, and on into the top plate. This will keep all of your stator pieces in alignment. If you use an epoxy, make sure you use some sort of "release" compound on the guide posts or you will never get the stator out of the jig after the epoxy hardens. A silicon or Teflon spray can work well in this situation. Spray the guide pins multiple times and let the silicon dry completely before use. These guide pins should not be threaded, so they provide a uniform positioning reference for each lamination in the stack.

Use a slow acting epoxy so you have enough time to coat and place each lamination in the stack and clamp the jig tight before the epoxy cures. After you clamp the stack tight, wipe off as much excess epoxy that is squeezed out as you can before it hardens. The more you can clean up the edges before the epoxy cures, the easier it will be to finish later.

Think each step through and build all the necessary tooling to make it right the first time. Make sure the guide pins can release from the mounting plates independently from the stator stack in case your "release" compound doesn't work perfectly, and the guide pins have to be pounded out later. Cover the top and bottom of the mounting plates with "release" compound, or wax paper, so the epoxy doesn't stick to them.

Test the system completely BEFORE you apply the glue, and make sure everything aligns properly. Don't be in a hurry. This is a very important procedure and it must be done 100% perfectly, the first time, for the motor to work well with a critically small air-gap.

Once this is done, you should be able to chuck the stator piece into your lathe and using a ceramic cutting bit, carefully re-surface the inner diameter (that faces the rotor) to produce a perfectly uniform curvature.

A similar procedure should be followed when gluing the rotor pieces together.

Well, that's all I can think of for now.

Keep up the great work!!!

Maybe super glue?

These days epoxy based glues are usually used for bonding steel plating. Superglue is extremely non-elastic since it's based on the celulosis compound.

[Jetijs]

Theres a small problem, the plates have a minimal burned "fuzz" on the cut edges. That means that I will have to remove this fuzz by scratching it off with a sharp knife. It is not too hard, but it is very boring, I spent whole day to get through the rotor pieces (about 200 of them), now I started working on the stator plates, its a lot slower, but I am slowly developing a remarkable patience
Also I think, that I will have to use some kind of glue on the stator plates, because the four bolts wont squeeze the pole parts tight enough as they are too far from the bolts. Any suggestions? Maybe super glue?
Thanks,
Jetijs

Elias, I just don't trust these geocities and imageshack image hosting services. Also the upload speed is slow from my internet provider. I will rather find another hosting service in my country.

A quick update.
As I promissed, my parts have been cut and I got them today. Looks very nice (see the attached image). Now I need to get a 4mm stainless steel rod and make a thread for the nuts on each side. Then I will be ready to assemble the plates together
Thanks,
Jetijs

Geocities

Hi all, happy and joyful new year
Just a quick update. I sent my silicon steel plates to the laser cutter and they will be ready on Thursday. Also my image hosting server is down, that is why you can't see any of my pictures. I am sorry for that, I do not know when they will fix that.
Thanks,
Jetijs

Hi Jetijs,

Why don't you put them on somewhere like geocities? It is more reliable and it is your web place. And of course it will be easier for other people to access all of your photos.

Thx for the quick response Peter,

I just wanted to throw that idea at you for your opinion.My thoughts were more torque, But maybe that arrangment might somehow have an effect on the radiant spike on a bifilar wound coil as well?,Dam back EMF.Let me just make it clear I DONT have ANY experience with regard to electronics in general (but I have built the bedini ssg to get my feet wet and try to learn about this field as I am EXTREMELY interested with this field of research).I have read most of the info in this forum and the other links in this sight as well as watched some of your presentations.Let me just say between you, Mr Bedini and Tom Bearden I'm just fascinated with all of your collective research.Ok, let me stop rumbling on.Thx for all the countless hours of research and I'll try not to be a Distraction to the excellent progress of this forum.

Confusion....

Hi Guys,

It's great to see such a good forum researching a better development of the electric motor/generator.Peter, I have to say I've been following your work for some time now and admire your persistence to show Less knowledgable people how various inventors motors may have worked and/or harnessed radiant energy.I just wanted to run a quick idea by you.With regard to the Teale motor it would seem that it would produce more torque if the end of the piston had a coil on it minus the distance the piston sucks into the stationary coil of course.Well,I dont mean to deviate from the great work going on here,but I just wanted to throw that out there.Also,Since I've seen you have visited with Bill Muller in the past do you know if he magnetized his cores when they were setting up.Thx in advance And continued success to all

Dear Gary,

Thanks for your interest in these ideas, and for thinking about these motor configurations. When you look through the historical developments of early "solenoid motors", you see that there was significant confusion about the relative benefits of a passive, iron plunger and a fully magnetized plunger in the solenoid. Both ideas are well represented in the patent record. The designs that use a magnetized plunger can produce MORE TORQUE across a larger air-gap, so many inventors believed this was a superior design. The normal appearance of Back EMF in the motors operation was expected. The inventors who used passive iron plungers realized that the lack of Back EMF in the operation of their designs was an IMPORTANT feature, and that torque could be increased by minimizing the air-gap between the stationary and movable pieces. Each group routinely discounted the claims of the other, and advanced their own beliefs.

For the purposes of this forum, maximizing torque "at all costs" is not the object of these designs. We are only interested in "maximizing torque" that is produced as a BY-PRODUCT of magnetic field production. You are correct that more torque could be produced by putting a second coil on the movable plunger, but this situation would cause TWO MAGNETIC FIELDS to interact, produce cross-inductions in each other, and create the dreaded Back EMF. So, that design reduces the machine to classical operation where COP>1 is unlikely.

Bill Muller's coil cores were made from compressed Magnetite and epoxy. They did not hold a residual magnetic field.

Thanks for your questions.
