Pulley System for Heavy Kiln Lids

This is part five of a multi-part series setting up a pulley system for heavy kiln lids.  Click here to go to part one.

Now that we've discussed the pulley, the rope or wire, and securing the rope or wire to the handle of the kiln lid, there's really only one more major topic to discuss.  It deals with the securing the other end of the rope or wire, which is used to hold the lid open once the pulley does its job. 

In most cases, this is done with a counterweight attached to the other end of the rope or wire.  Common weightlifter's free weights can be used as the counterweight, but it's possible to use any heavy object.  One advantage of free weights is that the weight can be varied so that it's easier to determine the exact amount of weight needed. The photo at left shows the simplest kind of installation, with the rope (or wire) threaded through a hole in the weights.  (Photo courtesy of Rebecca McGlynn.)

If you've chosen to use rope, it's also possible to simply tie the rope off with a bracket screwed to a wall.  This allows for easy adjustment of the height of the kiln lid opening. This can also be achieved without a tie off arrangement, but it requires some experimentation to determine the  precise amount of counterweight required.  (Photo courtesy of Dee Janssen and Kay McConnell.)

Coming soon - the next part of this tip, which will be a step by step discussion (complete with materials listing) of the building of a pulley system with counterweights for a two-handled coffin kiln lid.
