Ideas for small pulleys

[stheis004]

Have these left over from a sailboat I no longer own. There's gotta be somewhere I can put these to use, rated for something like 220lbs. Any ideas?

I got nothing that's just not some smart ass comment, sorry.

Too often people think that they need large diameter rope in MA setups. Not necessary.

You could make a little jigger with some small diameter cord for pre-tensioning limbs up in the tree.

Take a llook:

MA for a bigshot trigger? Old school rope walker system. Mini rigging demo's for training. Extra MA for pole pruners. 3:1 truckers hitch replacement for tie downs?

Earrings for the wife. Just say, "babe you have the MA over me any day."

Christmas tree ornaments or for holding a canoe to the roof of your garage.

Totally true, baby 3/1 !
perhaps 2 handed to 4/1!
or adding to, or better yet insetting inside a larger system
.
as technical side notes:
Larger sheave over same axle/pivot; is more efficient, because larger leverage over same axle frictions
and then too, especially on a tighter bight;
OUTER arc-ed rope fibers are carrying load, so larger rope in same sheave can give more leverage over frictions also.
.
As you are multiplying the forces with a pulley system;
you are also multiplying the in-efficiences subtracted thru the chain(so watch them closely).
.
When buying pulleys, the last few percentages of efficiency are the most expensive (going from 80% to 90% and above).
Those might be some pretty fine hardware!
.
'2 handing' not subject to all same frictions expectations/rules;
as the inset pull hand input pushes rope into final pulley (in 3/1 more accentuated for larger systems);
not drags it thru(greater efficiency)!

Like a fuse box with 2 sides, can work forces between 110v and immediate ground charge
OR
invoke both halves/legs of fuse box across correctly for 220v!

Except for 1 deft move, seems like 2 men doing the same thing with different results!
