I recently switched to drilling my blanks on the lathe. First off, WAYYYYYYYYYYYYY worth the minor investment for new attachments. My drilling has improved ten fold. I RARELY lose a blank in the drilling process, and the holes are always true and near perfect. no wallowing or anything.
After starting this process, i was turning the blanks round, then mounting them in a chuck and drilling. Well after some experimenting, i have found a solution!
I use a Nova chuck. Before, i would simply take the jaws off of the chuck and use the sleds to hold the blank. Now i use the nova soft jaws. I have not cut the jaws. I use them just as they come and they hold a square blank beautifully!
Anyway, just wanted to share this.. I was about to change all of my homebrew pouring molds to round ones but now i dont have to!
