This is a multi-part message in MIME format. ---------------------- multipart/alternative attachment Robin, As I posted on Tuesday, I slow the pull speed by using blocks (pulleys). To verify the specs on my unit, I measured the single line speed of the cable and clocked it at 9" per second. With pulley reduction, the speed of lift is 2.25" per second. It was a fast guess on my part when I was standing there in the store looking at pulleys. Now I might want to use 6:1 reduction if I had my druthers. But lacking that, I just give it short bursts at the critical moments and it works fine.
