Oh well, Not woodworking, but while I'm on a roll with Bob...
I know I put the rear view video cam in him last year, but when grading the driveway, I needed something a little more immediate.
Looking up at the sky was kind of hard and I really didn't like twisting around in the seat to look behind me.
So I bought a couple of little 8" convex mirrors and welded up a piece of 1" square tube on each arm to mount the mirrors too.
So now with new boots, eyes in the back of my head, I should be able to take out the big old bumps that the gravel delivery guy left for me on the driveway a couple of months ago.
I've learned that back blading is definitely a learned skill.
