John,
I did the same thing except I put caster wheels on the legs of the strongback cradles. I like your idea better! I kept breaking the smaller wheels when I rode over cracks in driveway.

Hey, how do your neighbors like the saw-dust plumes? That's a Laughing Loon boat isn't it? I built his Panache & love it!

: I fastened an old wheel on to my strong back so I could work on my Shooting
: Star out side in the fresh air and good light. Better to have the sanding
: dust blowing away in the breeze rather then in the garage. I have my radio
: taped to the strong back and the tool tray under the strong back holds
: most of the tools I need while working outdoors. Also the electric drop
: line feeds 15 electric outlets along the strong back so my power tools can
: be plugged in at any area I am working. The saw horses are fastened to the
: strong back. Working outdoors on your favorite boat is hard to beat.
