Here is a picture of JRods smoker..... just to give you an idea..... Dave
TRd I use 3/16 in all actuality most propane tanks are 3/16 i should know I currently have over 100 on hand. Do not flip out and try and make a full penetration weld it is not needed. I usually cut mine a little small and tack a welding rod to it and fit it in, you want some penetration because i would grind near flush then flapper wheel the rest.. Nobody will ever know and it want matter anyway.If you have a big patch whop a little raduis in it with a hammer and vice. Want take much whooping either!!!!
My tank must be the exception it measures 1/4 in. Thanks for the tip!!!.... It may not be as hard now I had to square the back of the tank and cut a sliver off... so I'll be able to use that for some of the patches at least
