RB Junior Rotary Attachment

(5 customer reviews)




This rotary sits about 7in tall with a 30oz cup on the wheels. The tower is slightly higher than that but is offset to prevent head from striking during use. Just be mindful when moving the head that you don’t strike the tower.

The RotoBoss Jr. Rotary Attachment is The Best and MOST VERSATILE Rotary attachment on the market today for your most any size Lasers!!! A rotary is a rotary except in this case it is unlike any other you will find. My Rotoboss Jr. Rotary Attachment like many others these days are made from lightweight materials such as 3D printed parts and Cast acrylic. I left nothing out of this design and added several key features unique only to this rotary. Running on a top quality stepper motor and the best mechanics I could get my hands on. This rotary offers the ability to raise and lower the slave wheels in a unique and precise way to accommodate most cylindrical objects you may have. Lead screw operated Axis makes quick and easy work of leveling your item without the worry of securing it afterwards. This compact and lightweight rotary will not leave you disappointed and comes with a 1 year warranty that covers any parts that may break. Also for the first year you will be privy to any updates or revisions that come out for the machine and all i ask of you is to cover shipping the rest is no charge.

This rotary comes stock with a removable cup clamp with 3 different size wheels and large heel plate so you are ready to roll right out of the box.

It works so much better than the rotary attachment that came with my machine. This one is well thought-out, and does exactly what I needed it to do: keeps the tumblers and mugs from “walking” out of alignment.

    After a very short learning curve and some sound advise from the owner, I really appreciate how good this tool is. It is so easy to adjust and go from job to job. Definitely worth the price. They ask you the right questions turning this into a plug and play purchase. The Mug Spacer is fantastic.
