Putting a stop to collet woes

Putting a stop to collet woes

Often, I am unsuccessful in locating a collet stop for a 4C lathe collet. So, I developed my own special system that uses a brass insert which accommodates various stop lengths.

Squirming out of a worm-wheel dilemma

My idea is for producing worm wheels without special machinery. Using an indexing head, I turn a worm and worm-wheel blank to suit a particular application by cutting slots across the worm and filing the teeth to form a cutter.

I then have the worm hardened. Alone, it does not pick up the wormwheel teeth, so with the indexing head, I slot the correct number of teeth at the proper angles into the worm wheel. After mounting the worm in a milling-machine spindle and centering the worm wheel on the machine's table, I pick up the worm-wheel slots with the worm and, at a slow rpm, feed the worm into the wheel to the proper depth. I've used this method for worm wheels up to 2 ft in diameter.
