Hi Kevin, what amazing work comes out of your little "TENT". You say you love a challenge but looking at the pictures of your "tent", you're challenge is more like a WAR. A tidy shop is safer. I found out the hard way. Tripped on 2x4 offcuts which I threw on the floor!!!!. Fell backwards and split the back of my head open on the edge of a sheet of 3/4" ply and got twenty stitches and a holiday. Don't worry, there was no damage to the ply or my brain. The medic said he could find nothing on the x ray of my head. So now you know why I'm the way I am, Kevin. Take care and TIDY UP. .
