Well I have been having issues trying to cut a perfect circle in acrylic and polyethalene. Not talking about 1/8" sheets, that easy to do with just a knife and ruler. I mean like 10mm and thicker sized sheets. I do not want to have to buy a rotary tool just to do the job..



edit -- just ordered this.. I can just put it in my drill  . Does 1 to 12 inches.

Hours old tops.

And yours are from when?

Hi Exx
Your showing how if you put the arrays close enough you get one big block magnet, all the flux starts from the middle and moves down and around to the opposite side and up and around to the opposite side so because the flux is moving down and around at the bottom its pulling your roller in but its moving the opposite way at the top so it wants to pull your roller back in or to the closest pole, this is why I have just two magnets side by side in the stator of my onewaygate and you showed the difference it makes having just two magnets, the onewaygate wasn't just thrown together after seeing how something reacted it was put together after lots of test in a way that makes it work best.
On this point I have two things to say, first the onewaygate was made as a gate to attract in and leave on a level surface and two most magnetic systems will go up and over a hill if the magnets you are using are strong enouth.
Take Care Exx

Run that thing really slow Rasta. Use only if you have variable speed drill. The bigger the hole, the more dangerous it is.

Oh yeah I will. It will all be clamped down on my work bench / table extremely well. I will be using a 1/3 HP variable speed electric drill. Hopefully will arrive in the next few days since it is the weekend, but fed-ex is usually pretty good. I was going to go the dremel route.. But damn, I would end up dishing out like 100bucks for the dremel and proper accessories.  So I opted for the other choice.. It can be used with quite a few types of materials.

Hi Rasta, who is the manufacturer and what is the maximum thickness that can be cut?
