I just built four. Cut the tops off, welded legs on, built rotating racking arms and sealed lids
This maybe a little over kill but that's my biggest problem. I can't just do something simple.
I think what the guy's said above with the orange cap would work just fine. If you want to be able
to clean the inside easier then cutting the top off is the way to go. I found 12 inch lids at the local
restaurant supply store, cut the hole a little smaller and fabbed a bar to fit under the handles with
a set screw to hold the lid tightly in place.
