Harv, I said I'd let you know how the block and tackle system worked that I rigged for can lifting.........it was, simply put; simple and easy. I'm somewhat photographically challenged, but I think I can explain the whole thing easily. I started with one double block pulley and one single block pulley I bought at Home Depot for about $2 ea., a screw-in hook for one of the barn trusses, a length of rope (brown, in the barn when I needed it), some tubing and clamps to emulate the filler hose you had in your picture, and two 3" "S" hooks that I bent the top closed on. The block and tackle gave me a 3:1 purchase on the lift - real easy to pull.
The "S" hooks were used at the ends of a rope that was allowed to slide through a bowline knot (small loop) on the end of the rope running from the pulleys, allowing the fuel can to be hoisted by attaching the hooks to both handles (top and side) before lifting and then simply sliding to a more horizontal position when dumping the fuel. This piece was custom made using an empty can to get just the right length.
I also put a garden hose shut off at the end of the filler hose and used a garden hose male end to get this to attach to the clear vinyl hose. This allowed me to put in as much fuel as necessary and then stop the flow. A
B7100 doesn't have a real big tank and won't always take 5 gallons of fuel, so I could hoist the can, position the hose, and then turn on the flow.
The only dilema was what to do with the rope in my right hand after I pulled and lifted the can. Solution: since the rope was longer than needed for the first trial run, I simply made a loop on the end and slipped it over the vise on my workbench. Any immovable object would work.
All told, I have less than $8 in purchased materials for this system. Works for me. This is one of those things where Harv really deserves the credit for a good idea. The thought process to solve the problem was simple and perfect.
I hope this all makes sense. This was really simple to make. Took all of about 15 minutes, and is hanging there near the entrance doors whenever needed.
