I promised pictures and more experiments on my Lee pot mods, but then I got busy and never had time to follow up.
I've used the modified pot a few more times. The good news is that drips have been rare. The bad news is that the orifice plugged up, probably with crud, and flow was reduced. I didn't have time to drain the pot and clean the orifice, so I went back to the old reliable ladle.
Perhaps a retired person who has a lot of time on his hands could devise an easy, cost effective solution for the Lee bottom pour pot. Myself, I've got better things to do.
You have to wonder why Lee doesn't make the improvements ? Continuous improvement does not seem to be part of the Lee philosophy.
I cannot recommend either of the Lee bottom pour pots. Get the ladle pour pot instead.
