The worm gear assembly came on Monday and Jeff, my friend and guy-who-can-do-anything, came yesterday afternoon to begin the installation. Several problems were encountered along the way -- like starting with Jeff not having the right size allen wrench in his collection of dozens to fit the bolt holding the bracket to which the beam was attached to the loom.

Next problem... when Jeff & I measured the axle of the beam to send diameter to Larry, at Fireside Looms, so he could machine the hole in the gear we mis-measured by a fraction of a fraction of a fraction of an inch. So when the assembly arrived we had a gear with a 1" diameter hole to fit onto an axle that was about 1.06 in diameter. Solution? Here's Jeff with an oscillating sander reaming out the hole to make it a tiny bit larger:
