Topic tags/keywords: turning knobs tip

I recently made a what will become a jewelry case that included 16 small drawers. Each drawer has an ebony know that began as a 3/8” x3/8” cylinder with a 3/16” tenon. A Jacobs chuck in the headstock was used to hold the knobs for turning. While woking on the first knob I realized that the situation was quite dangerous as my spindle gouge had to just about touch the tips of the chuck. I wanted to put something between the tips of the jaws around the tenon as a safety device. I fist thought of using thin plywood, but even the thinnest plywood would be too think and I wouldn’t have enough of the tenon left for the jaws to grasp. I got lucky, I keep all my old hotel key cars and all the other plastic cards I use to spread glue. I realized the plastic would be both strong enough and thin enough to be may safety shield. I’m sure others have thought of this before, but I thought it was very clever.

Great idea. I’ve used thin ply but as you say, sometimes it’s still too thick.
