This is a test animation of the Muchni (the wooden structure which raised and lowered the Kiyor) where I was trying to work out how the gears might have been arranged. The challenge in designing the Muchni is to find a way for a Kohen to raise a 5,000-pound object (see the earlier post for details) singlehandedly. In my design I use a counterweight on the back of the Muchni and reducing gears to make the task of lifting the Kiyor more manageable. This early animation only shows the gears moving but not the Kiyor or counterweight.
