wonderful & thank you for your ideas...!!! i have almost new food grade 5 gallon buckets , i am using them and they already have lids, and then all i need is the bottom pan, i been looking around and will go price checking, for the black plastic oil pan, or large flower pot bottom pans , which ever one cost less, thats the one...! im getting..!! HA, so almost free is better then buying it all...!! is my motto...!!Good ideas. You could also use plastic to make the tube: perhaps a small trash can, cut the bottom out of it. Or use a larger plastic bucket, simply cut the plastic, and pop rivet it to make the right diameter tube. Left over pieces of aluminum flashing would also work well. Size your tube to fit a 6 - 8" cake pan which would be the lid.
