This is a flywheel I made for a magnetic motor that does not work, but making all the parts was fun!
I started with a table leaf of poplar laminated on both sides with mahogany. It has a ring of 12 lead weights in the perimeter and I laid out all the corner holes for the spoke cutouts in the wood lathe. I find that is a whole lot easier than trying to layout the patterns and scroll sawing them to a very uniform pattern. It is like connect the dots ( holes) then. I added some in process shots and one where I’m turning the lead weights to fit the bores.
It is finished with Danish oil and clear lacquer.

Below are some process shots of the motor. I have an idea for a better one with 3 rotors and I have done some modification to this one with a spinning wheel outboard of the rotor that really makes it spin, but needs a power source to make it spin.

I see I don’t have a shot of it fully assembled from the side. I have video but it won’t post!

Cheers, Jim

Looks pretty sofisticated to me. I see lot of fun in it too.

Jim, it looks to me as if you are attempting to make a perpetual motion motor which is of course not possible!

Cool Jim. It almost looks nautical. I really like the jig you have rigged up to cut the offset holes. Utilizing the tool rest is great. I see this on my list in the very near future.

Beautiful flywheel. I can’t wait to see what you do with it.

Interesting project! Looks like you had to build several jigs, too!

Enjoyed the pictures, and I did watch the link video you sent me, It was interesting. you may have to build another rotor. Still is a great project in engineering. Flying west today.

Great looking parts you made for a interesting project and hope with further study you will get it to work .

The jig you used for drilling the holes on the edge of the disk is pretty neet!

It all has the appearance of old style scientific equipment. As much detail in the construction as with the device itself (and not a hint of plastic)!

Hope it all works in the end (and you have just way too much time on your hands 8^)

A very neat project!

Thank you all for the nice comments. I was not going to post this because my idea for the mag motor did not work, but the flywheel came out okay.

Hi Harry, I’m still pursuing a working magnetic motor. There is a patented Perendev motor that does run on just magnets and back in 1954 Howard Johnson received a patent for one and then he died. I also heard that Nicola Tesla was working on when they burned down his factory. I have the Design of the Perendev motor now and that is a future project ..with 3 rotors at 20 degrees apart….made of wood, of course!

Hi Bruce and Ralbuck. I’m retired and this is how I like to spend my time instead of golfing or sitting in front of the boob tube watching mostly commercials.. This is more fulfilling and keeps my brain cells working. Working on this computer takes away of a lot of shop time, though!!.

Cheers, Jim

Wow that’s a pretty tricky make there Jim, a lot of engineering skills required to sort this out, well done Bud

If you could make Magnetic Dominos that when placed on ends and one gets pushed to start the Fall-Chain, where magnets could reset them, to do it again, you would have an endless LOOP of falling dominos…

Are you trying to make something like that but going in a circle? :)

Looks COOL… Interesting…

Mate you never cease to amaze. Congrats on another top3.
Are you doing a video on how this motor works?.
Would like to see that.
