Re: Mast tabernacle project
Sky's absolutely correct.. the leverage exerted by the mast will be huge, but it's sneaky.. straight up it may be/seem manageable, but if the stick gets out of plumb in either direction you'll have a hell of a time keeping it from going on its own.. esp if it gets out of line with your tackle.. I reckon out of control it may well do your tabernacle in on the way down.
There are systems and methods.. I think they all provide some means of limiting lateral wander as the mast is lowered.. Lowering forward leaves you the minimum advantage and working area.. lowering aft would seem a better idea.. wider platform and longer distance for reduced leverage of the overhang.
Best of luck and work safely!! Anyone trying to be a hero and 'catch' a toppling mast is going to be in for a fair bit of hurt...
