Worm Wheel Hub

[epanzella]

Made a clamped and keyed hub for a worm wheel to be used in a future project. First time I got to use my shop made slitting saw arbor on a real job. This is for a head lift transmission for my mill that has to be assembled in situ so I can't press the worm wheel onto the shaft. This steel hub will be pressed into the aluminum worm wheel and then slid onto the shaft. The four cap screws and two caps will hold it in place and pull the hub against the key.
