Hi Eric

In my first post on this thread I already have linked to your excellent site  ;D

I am going by the metric dimension sheet from the links.

Good stuff and well done.

Cheers

Sean.

Hi Eric

Did anyone else give Followups that have not been posted, I know it was 4 years ago.

What did you think to the statement made by Bowmans friend, regards the magnets?

Hello Sean.

Back in 2004, 2 devices of Bowman were replicated. The device from 54, and the device that Bowman's friend mentioned. See attachment.
Many different set-up were tested. With magnets pointing in different directions. But with no success.

Workmanship is a very important thing in this devices. Bowman used fish-oil in his beatings. The device was made with watchmaker precission.

I noticed that you use different materials and magnets, then the original device. Not sure if that is a good choise. In 54 there were no NEO's.
Plastic gears have less mass then the metal gears.

Threaded Rod turned up.

So cut to length and lathed down the ends.

(http://www.overunity.org.uk/bowman/rods1.jpg)


Perfect fit and they are so loose but with no movement back and forth, took a long time on the lathe shaving 0.2 mil off at a time, but worth it :)

I lined up the Cogs to see if I got it right and again perfect fit  ;D

The M8 Brass nuts and washers did not arrive today, but hopefully tomorrow.

Cheers

Hi Eric

I have ordered some Alnico magnets and waiting for them to arrive and also have different Rotors in mind for them.

For now I want to try a number of different configurations and using what magnets I have here.

The way I have built the Frame should allow me to swap back and forth different Rotors.

What I noticed with all the other replications was that they did not really reduce their losses with regards friction by using big bearings.

Is there info anywhere else on the second design?

Cheers

Sean.

Does anyone know what happened to Douglas Mann who claimed to have a Bowman Motor working and detailed his construction in detail at this link

The problems were not the bearings but the aligning of the shafts. Aligning the gears at the back, the long rods AND the magnetic gears in front gives problems if the fitting is not 100%.
The first thing you can do to find out if you are on the right track is checking if you can give one of the gears a spin and see if all rods keep spinning some rotations. If so, you can start testing with the actuator. Otherwise you have to align. Since you use CNC, you probably have a good alignment from the beginning. As you see on the other replications, moset devices have everything adjustable. The gears were metal for the flywheel effect.
The device on my website is 100% based on the device that Robert Calloway built and claimed it worked. During the project Robert gave advice to the builders.

Yes, I do.
He still does experiments with free energy.

Hi Eric

I want to use Brass nuts and washers but they are not here yet. But I wanted to check the alignment of the Gears and used some Steel nuts for now.

Here is a small video showing the Gears and their looseness as such.

I also popped on the magnets I had just to get a feel for the magnet interactions, I was surprised.

Did he never re-build another Bowman and show a video? I find this very surprising.

Shame really

Today Overunity.com has been really slow, but seems okay at the moment  ;D

Many thanks for the link will go take a look!
