Laser Rotary hold down device.  Adds pressure to your cup or glass while engraving.

Same Item I make and sell on Etsy and Ebay.  Just a bit cheaper as I have no listing fees.

This device prevents the item being engraved from moving outside the correct motion of the rotary. And provided the ability to make multiple passes on one item. Eliminates scrap and waste due to mis-alignment of a cup of glass during engraving.

Made for the Chinese four roller engraving machine. See picture for rotary that this model fits and mounted with cup held down.
Color is dependent on my material supply, usually black or silver, maybe blue or grey. All depends on my material stock.

Using PETG for added strength.
Items needed to use: This set of parts, a drill and tap to mount to your rotary. (two holes needed You can drill slightly oversize and not tap)
To mount, mark center line on the plate, mark for hole one inch on either side of the line. Drill and tap to 8-32 Plain screws included. Assemble the parts, Mount on the plate with provided screws. I Have Altered spring pin, so the spring fits over the pin and stays in place. If you want to remove, just remove spring and the pin and leave plate on rotary.
I'll print out and send a set of pictures showing assembly with your order.

I've also included a short arm with carriage bolt for adjustment. Mounts without spring and turn bolt to get arm horizontal.
only used when you are engraving a Bottle and need a stop for the bottom. Doesn't do any sort of hold down, just a simple stop.
