How are you guys holding beer mugs for engraving? The handle is too heavy and it causes it to slip when using the friction roller wheels rotary attachment.

I also have the three jaw chuck type rotary, but have not figured out how to grip a beer mug with them since it is metal on glass.

Any help would be appreciated.

IMO a chuck type rotary is ten times more useful than a friction roller type. Other will disagree no doubt. A beer mug is just one example.

However the chuck itself is only useful for some things. To get the best from this type of rotary you need a range of work holding fixtures.

At least as handy as a chuck, and probably much more so, is some cones. A few sizes, both external and internal.

Try rubber pads on the inside or outside of the jaws on your chuck. Don't over-tighten! Look for some thin weather striping.
