I'd love to see/ hear what others have done. Oakwood
I've been helping out a fellow builder develop a lift system for his boat. Thought I'd share my system here, in case any of you were curious.
Here's a video on YouTube, showing the pulley system.http://www.youtube.com/watch?v=CW6al3d0rXY
...and some snaps/ schematics at http://picasaweb.google.ca/dwclow/PulleySystem#
Obviously, the top 2x4’s need to be securely ‘lagged’ into ceiling joists.
I’m not sure if it is easily evident or not, but the whole system works with only three lengths of rope.
I'd love to see/ hear what others have done.
