I'm with pianomanpj. I'm not a big corian fan, but I do like that one. Although, I don't know what jelly belly jelly beans are.
I just started using corian and noticed that on my first two pens, I solved the issue by pressing the Nib and Final into the tubes before I turned the blank (this sizes the tube) then removed then Nib and Final and turned the blanks had no cracking after that.nice looking pen, i gave up on corian , everytime i assembled the pen it split. Any body thats successful with that stuff deserves a medal IMO.
