Why not just get an electric winch and use a single block if it is something you use frequently, 30-40lbs doesnt sound too much of a load to haul up?

My wife never answers calls from Caller ID withheld, I never answer the telephone ever

I think if you get left hand lay rope the problen isn't so bad, I seem to recall it was used for lifeboat falls. With a 3 fold purchase there is a way to reeve the rope so it minimises the twist but it is the nature of rope to twist itself into a "thicker" rope. If its not too high a lift can you not have a tag line attached to the hook for pulling the hook down, I'm assuming you are working single handed and have to load the hook, if you have a helper they can pull down on the tag line. All this is going back to my pre-sea training int early 60's. If you know any rigger's they could probably advise.

Scratches head ?????? If it exists I thought it was there, eg Full Frame Camera is there, how many times have you read "....if Pentax did Full Frame..."

Because it's there

Lots of info on block and tackle even mentions the loss due to friction of the sheeves 1/10 IIRC

I thought asiatic women tended to be on the tiny to extra small size

I like those "caravans" with all mod cons

No, my neighbour had to sell his. His wife told him he could keep his N*ts or his Nag but not both

Unfortunately his work doesn't come across all that well in the book I aquired at a jumble sale "Ansel Adams Letters and Images 1916 - 1984" I would very much like to see the same photographs in real life as I think they would be very impressive.
