hmmm...... I took off the first stage and tested it, same readings, I am keeping it off, it was kinda worrying me anyways... I took apart an old vacuum and I am using the bearings out of that for the shaft suport, I have all my brackets welded and ready to mount, now I need a longer belt and some hose, I will keep this up to date, i will also see if I cant borrow a camera.
