Butch,
Your ideas are one of the ties that bind us in this quest to harness magnetism,

1200 ideas and concepts for a design? WOW

How many did Edison and company do before they got a light bulb ?

They persevered and got the Bulb,

The odds are with you Butch!

Thanks

Chet

Broli tell the boss you want to Moderate your thread?

exnihiloest, I'll say this early on irregardless of your content. Please refrain from posting in this thread which I created. This also counts for your friend spinn_MP.

Thanks.

OK, a fair call...
Similar call kept me from one of the more successful  threads, for years...
(E.g., the "Jule thief" stuff...)
No harm done.
Cheers!

They say the Aboriginal society went for 50,000. years with out inventing the wheel [they never did]?

Some guys don't look for change,some do!

You do you!

Became really busy last days so couldn't do much design work. I have made this crude rotary version. I think this would reduce complexity and issues arising from a linear system. The most important thing is finding cores that large. I actually found a relatively cheap substitution. Steel strapping. These can be bought with all kind specs and above all they can be bought pre painted. This would eliminate the eddy current issue.

The presented design is really a crude setup I made in the little time I had, it's missing some functional things, but imo this is the way to go.

I really like the pre-painted steel strapping idea for the cores.  A rotary system does appear to be much simpler than a linear system also.  This is a good start, and the best thing of all, it can be done without the need to have the parts machined, etc. which should reduce the cost.
