Pulley System for Heavy Kiln Lids
part four of a multi-part series setting up a pulley system for heavy
kiln lids. Click here to go to part one.
Once you've secured a pulley and determined
whether you want to use rope or wire, the next step involves tying
off the rope or wire at the two ends:
Securing to the handle
Securing rope to the handle is fairly easy.
It only requires that the rope be tied in place, using any basic
knot that won't slip. A standard "Figure 8 knot," commonly
used in mountain climbing, is easy to tie and strong enough to work
well for this purpose.
Click here for a demonstration of how to tie a
"Figure 8 knot". You
can also loop the rope through the kiln handle and secure it to
itself closer to the pulley, as was done with the rope in the top
photo on yesterday's tip.
a wire or cable to the handle is a bit more complicated. Most
are too stiff for knots, so require special parts to make the
connection secure. The photo to the left shows one system for
doing this, which involves using screws and a horseshoe shaped
bracket to hold the wire in place.

Kiln lids with two handles instead of one are a
bit more complicated. Securing wire to this kind of handle
will be discussed in detail in the step-by-step example coming later
in this series.

this tip, which deals with the use of counterweights and methods of securing the other end of the
rope or wire, which is used to hold the lid open once the pulley
does its job.
