This is my second Wimshurst machine. This one is slightly smaller but also has a very unique drive system for the disks. I had a die cutter made to spec for the copper foil segments. The copper foil is a peel and stick tape and it worked very well. At least is dry weather I get up to a 3.5” spark which is pretty good for a machine with a 12 inch disk. My first machine was capable of about 4” but it had 15 inch disks. I’m addicted to these things. They move, they function, make noise and make very cool sparks!

It’s made from riff sawn white oak. The tree was cut from in my neighbor’s yard a few years ago years ago and I had an Amish saw mill cut it into quarter and riff.

Pretty neat! Can you rig it up to start my wood stove?

I was looking for a Playing Card with a clothes pin holding it in place… for sound effects… :)

Otherwise, quite a very COOL project!

Norman: Very cool device!

Joe Lyddon: It has to be a Yogi Berra or Mickey Mantle baseball card, like the ones I ruined on my bike…..

Tesla was a genius, but the kudos for this baby goes to Wilhelm Holtz and August Toepler, and others who came later with more refinements.

The build on this machine is outstanding. Mork your attention to detail is,,, shocking – ly beautiful.!!!

I guess you might call it Steampunk but the mix of brass copper and wood certainly gets attention. Of course the facts that it functions and makes a big spark doesn’t hurt. Oh… and the sparkle of acrylic transmits the reflections of the brass and copper really adds a lot too.

Working with acrylic is fairly easy and woodworking tools do pretty well. Melting can be a problem in some cases but most often sharp tools overcome this. One cool aspect is that you can rough sand, remove a few burrs and then take a propane torch to all the cut edges. It hides all the saw marks and makes the plastic clear in seconds. Gluing is also super easy and quick with Weld On glue.

The brass requires a few different tools but I did use my wood lathe a lot (fitted with a metal lathe chuck) to drill and also smooth all the corners. The gray plastic for the disk hubs is PVC which is very cheap and easy to work with and to my surprise glues well with the same Weld On glue.

If anyone wants to build on of these things contact me and I’ll give you some pointers. I have made a few mistakes I can help you avoid and it’s hard to find much good information on how to make these things.

Thanks for all the compliments!
