John E Davies Posted January 10, 2021 Share Posted January 10, 2021 (edited) I had no idea, I am highly impressed. I was starting to install a computer fan below the floor for moderating temperature fluctuations. I was really shocked when I hit metal.... 😳 My one hour job turned into four. I was using a 4” hole saw and 3/4 of the way through my Dewalt drill gears blew up. I finished with an electric scroll saw and a hacksaw blade in a straight handle. Then I went full analog and got out my 20,000 rpm air die grinder. Ugly..... fortunately it will all be hidden. I want to keep moisture away from the laminations, so I wil seal all that with epoxy before mounting the fan with an aluminum plate. Which I also made today.... I am beat. I ordered a new drill too.
