I got it... LOVE IT. It's pretty slick. Really nice for squaring up the ends, I do alot of beadables, so it's nice to have really squared up ends. You do need to have the glass pretty balanced around your mandrel, it won't automatically center your cylinder as your mandrel can still move up & down the slot.
It's wide enough to get the full width of a bottle stopper bead [bottom] flat & squared up nicely... I just made a disc & used both the inside & the outside of the squared side of the shaper to flatten & square up both sides of the disc. Very nice.
It might become unnecessary in a few weeks when I get my EMS, LOL, I purchased this shaper a few days before deciding to pick up the EMS... might be fun to use w/ it...will see.
