Default Threading holes into an aluminum pot

Has anyone thought of drilling and tapping threaded holes into the wall of an aluminum pot? With many people wanting to go electric, myself included, it seems like it could be a better solution than some conglomeration of nuts, washers, o-rings and things. I like it because I can't find anyone to do food grade welding easily.

I guess you could use it for Your heating element, your thermometer, valves and drain. Just put a high temp o-ring in and thread it all the way in. You would have to be carefully as aluminum is not the strongest metal but you wouldn't have to have any nuts in you pot. That just sounds dirty!

So, Has anyone done this or thought about it? Thoughts. Input. Suggestions.....

you wont get to many threads in the side of a pot I think it would strip way before you get it tight enough to seal .

unless you have really thick pots, I don't understand how you could thread it. Mine is less than one thread width thick...if that makes sense.

They actually sell bulkhead adapters that eliminate a certain number of assorted washers and junk. They are just a bit pricey. Not too bad for something thin like a kettle though. Then just add a spigot and/or a pickup tube.

I've seen some nice thick aluminum pots, probably near a 1/4" thick. You could certainly thread that for a bulkhead but I'd still want to back it up with a locknut for strength.
