Here is the finished 3 Jaw Chuck Rotary based on the Longworth Chuck Design.
Like the roller version, the most expensive part will be the stepper motor. A lot of the design is similar to the roller design.
A few things to note: Getting used to setting it up for lasering takes a bit of practice but it is easy to set up and use when you get used to it.
I have changed the faceplate design slightly from what is shown in the manual. Instead of the faceplates being smooth on the edges, I have added bumps in order to make it easier to rotate the front and back in opposite directions.
I have used the two I made (my original and the one I made for the manual so I could take pictures - note to self: the Samsung S25 takes really crappy pictures and the phone may end up thrown against a brick wall) to make more than 40 mugs and this design has worked great.
Attached are some pictures, the manual and the Lightburn files for both Standard and Metric versions.
HelloCS
I want to congratulate you again for your excellent altruistic work. Once again, I will enjoy this new mandrel rotator. People like you CS, are what the world needs, people capable of practicing honest altruism. Thank you very much for your generosity. Greetings.
One item to mention, if someone plans on building both the chuck and roller rotaries, they only need to make the base that is designed for the chuck rotary. Except for the angle assembly, they use the same basic design.
When using the base for the roller rotary, just screw the bolt that sets the angle up all the way so the base sits flat. All that is needed from there is to change out the motor assemblies and the rear assemblies which involves removing one nut each. That way only one base needs to be made, which is one of the reasons I designed it that way - the other is because I was watching the Red Green show when I was building them and got lazy.
I’m surprised I didn’t add duct tape to the plans (Old Fart Canadians will know what I’m talking about).
Remember, if the women don’t find you handsome, they should at least find you handy.
This looks amazing! Great work on the design. I agree, getting the setup for lasering right can take a bit of practice, but once you get the hang of it, it’s smooth sailing.
