Nice video, I didn't have any of those type of bits so reading around here and the internet I found out that a 1/16 bit should work. The smallest I had and a ltille bigger than the present hole. I did use a cordless electric drill and was very careful drilling out the orifice. Mine worked on both burners and I did try my burners on NG before I drilled them out. They worked but at a low burn.
I do not use any water in my water tray, I filled it with lava rock. My turkey smoke came out perfect and this weekend I plan on smoking Pork Ribs (YUM).
I also noticed the covers and that they are OUT OF STOCK.
Bought a cheap WalMart thermometer for $11.00 on sale and so far it works great.
I agree....this site has a LOT of info and it is easier to learn this way than the hard way.
