  • Perfect work. Unspeakably.How you arranged the magnets - N-N-N or N-S-N?

  • @MsAlexbobo

    Thank you friend. Yes the magnets are 1/4 x 1/2 x 2" neodymium and they are nsnsns.

    Thank you for watching.

  • I'll have to study the super-caps some more, but I'm thinking the operating voltage is engineered to work around the 3.5-3.7 volt lithium cells? Tapping? I've worked with many metals, and used thread cutting and roll form tapping, so I've used tapping fluids for steel, a different one for stainless, and yet another for aluminum. Delrin, I've used that for shaft/bearing seals in food processing equipment, mainly on stainless shafts, with the 'lubricant' being the process fluid, usually water

    I personally haven't seen a super cap over 2.7, but there may be some. Yes, I used to work with a lot of pre hardened steels, Viscount 44, 4140, Stainless etc. Then some of the hydro carbon tapping fluids are necessary. You already know TapMatic and similar have a formula for almost everything, but I'll use Edge in my basement workshop. This Delrin was given to me from an engineer at NASA about 40 years ago. It's really quit good and a waste to use for a simple rotor.

  • I've just recently seen the 'supercaps' on here (other youtube sites)...seems most are 2.5 volts? And the plexiglass...do you use some kind of lube when tapping theholes?

  • @dougspair

    The super caps I have here are 2.3 2.5 and 2.7 volts. I use a tapping fluid called Edge, but sometimes I just use Marvell Mystery Oil from the auto store.

  • @DadHav I'll study the super caps some more, but I still have a few salvaged electros from stuff...50-60K mikes,and 25-50 volts..mostly from 5v and + -12v power supplies. Tapmatic, yes, I even have a drill press spindle mount tapper I found at used tool sale.

    Delrin, that stuff was never cheap ! The shaft seals I made were for food processing, raw potatos, a lot of water..most all 304SS materials, UHMW is real good for this stuff, but absorbs enough H20 to fail bacterial requirements.

    Many people use wood for their frame. I have never notice any static electricity on the frame. Although I have thought of trying purposely to get some. Maybe it could be used.

  • Instead of plastic that still sometimes holds some kind of charging residue. Why don't you used wood frames and a lot less expensive? How much for one off your circuit boards if you sell them?

  • Beautiful work. Just subscribed. Looking forward to seeing more wonderful creations.
