Peaspurple suggestion sounds good I never thought of them. I tried searching the net and found a few but where I work we have laser cutters and they cut me a disk so I stopped looking. You could check a few metal shops or weld shops in your area if they have plasma cutters they could do the same. I really like the way it works because all I want is a barrier and the sand just wasn't what I was hoping for. Clean up is still easy I foil the disk only and haven't had to change the pan foil but once last Summer. The temps are easy to control because there isn't anything absorbing the heat before it releases it like sand or water. The foiled pan would probably be just fine it's just that I read where a couple of people said they warped the pan by running it empty and the disk I think will keep that from happening.
