You are correct John. After doing some research it seems that the only really safe way is to grab a commercial cooker for this job. I think that’s an option but it will have to wait until I set up my outside kitchen. There are a few places in my area that carry pre-owned equipment so it shouldn’t be terribly expensive.
It appears that many people are using regular pressure cookers for this job and there was a series of "chicken bucket" pressure cookers in the past but apparently they had some small issues with them including explosions and fires….things I don’t want to have to explain to the condo association.
