So I bought a small box of tap wrenches, and it had a dollar general dial caliper in it, as well as this. The guy had no idea what idea it is, and neither do i, he seemed to think it had to do something with machining
The "roller has 2 textures and 3 different sized wheels that thread on.
Looks like it could possibly be used for making those popcorn patterns on a wet wall (concrete or paint) before it sets or dries.No, disregard. It doesn’t roll, from the looks of it.
