Back from a vacation to find some magnets in my mail box. Even after 12 hours of driving I could wait. Once again a shout out to 30mm madness. I used 3/4"x3/8" disc. Used my 3/4" fostner bit to drill out the tab. I drilled smaller holes downward for the JB to have extra surface area, I then drill two bleed holes to allow the over flow to escape. Once secure I placed the torso platform and allowed the second magnet to match up. I then covered it with JB.
