Thanks for the video George. I didn't have enough common sense to think to look at youtube.
I don't know much about the unit that I'm going to look at, except that it has been sitting unused in a workshop for the past three years or so. I'll know more by the end of the day.
Alan...thanks for your comment. I will take a look at the pulley(s) and see what they are like.
Leaving in a couple of hours for the coast, so I should be there this afternoon sometime. It's a long hike! About 500 kilometres.
OK, fess up...which one of you clowns stole my sig? It was right here a second ago.
