Did you try your etching on the aluminum before casting on this one? Just wondering if you thought that helped with the chipout. More often than not, if I've got a cell on the end that's unsupported by the bushing, then it's going to fly off at some point. It's not been to bothersome, since if it's beyond the bushing it's getting turned off anyway.
I just started turning a honeycomb blank (that I ordered from your link) and immediately there was chip out. Any suggestions? Not wanting to continue if there is a certain way to turn these. Thanks!
