How to fix loose jaws on a chuck rotary for a laser engraver

In this video, we show you how to fix the jaws on your chuck rotary when they become uneven or loose.
We typically find the jaws will become loose when you are trying to fit them on an object that has too wide of an opening such as a large mug.
This chuck rotary is what we use with our 80w Co2 Laser Engraver

I know the video is a bit old, but the info is still good... I do just want to add that if you've removed the teeth to put the other set in (one set faces in, one set faces out) they might have been put in out of order. Inside the track of the teeth on the side (of most models) is a model SKU and a number (1,2,3). They go in order counter clockwise. =)

I am new to laser engraving but I've been using scroll chucks in my machine shop for many years, so I can confirm. Always a good idea to mark the jaws and chuck if they aren't clearly marked. I use a battery powered diamond tip engraver tool (like a very low power Dremel, but sized closer to a Sharpie) for this sort of thing. Very handy to have on hand for many such tasks. That way the marks can't get erased.
