I bought a Bayou Classic Double Jet cooker and cut a 40# propane bottle in half. for the pot

I used the valve fitting for the bottom dump and used a 3/4" round rod lapped into the hole for the valve control.

I have run about 500#s through it and I am ready for another 200 #s maybe tomorrow if the weather clears up

Good luck to you there are many ways to melt lead.
