Picked up one of the PSI bottle stopper kits, including chuck, stoppers, blanks, tap, etc. I had been messing around using the silicone stoppers on the dowels, and just using raw cork (Hint, corks compress or expand depending on how they are mounted or at what RPM they are spun, makes for a real treat when trying to turn to a specific diameter).
My first BS went great. I love making these things now.
Next one is a beautiful Paduak, finished with a couple coats of Shellac, grooves inlaid with gold leaf, and then a few coats of Poly. I had to cut it off the chuck, as the poly had formed a film over the chuck. So I have to rework it a touch to get that sharp edge off. (Going to use a thin washer to offset future pieces from the chuck when finishing from now on).
I placed it on the stopper, and it's out of round. One side is >1/32" off from the edge, while the other side is flush. I try a second stopper, same thing. I mount it back on the now cleaned up chuck. While it does sit a bit prouod because of the finish, it's even all the way around.
My first turning was dead nuts co-centric with both the chuck and the stopper.
Could PSI have a run of stoppers (The chrome and silicone part with the bolt) that aren't turned properly? One of them that failed actually feels a little lumpy on one edge.
