The Lee dipper is no good. The Lyman dipper is good, and right handed. I threw the Lee dipper away years ago.
For the water-cooling-the-sprue method, see the Cast Boolits-Aimoo forum/list. I use 1 mold at a time.

The Lee dipper is good for stiring, and removing WW clips from your pot..

Get an RCBS ladle and either drill and tap for the handle on the offside or pay a machine shop to do. Plug the orginal hole with a bolt, screw the handle in the new hole and you've just got yourself a left handed ladle. RCBS must be making the ladles for just this as they put a nice flat on the offside making it easy to do. Unbelieveable how much nicer a left hand ladle is than a right hand ladle for a lefty.
