I can't seem to find the specs that someone listed for drill bit size for drilling the spout on their Lee to increase flow. Any help will be helpful. Thanks, fellas.

Just something to think about. I drilled my Lee 10 lb pot out many years ago when I only had a hand drill. I wasn't perfectly straight and the drill left a bit of a groove on the inside of the spout where the valve/rod meet, not at the tip. The valve has a rounded end and where the groove and hole met the valve/rod it leaked. I got more flow as I wanted but it didn't leak before I did it. It would be nice if they made the valve's screw in so you could replace them.

Just my 2 cents worth!!
