Long time no post. Good to be back.. I have decided to join the world of the UDS. One question. I am using a barrel that once contained methanol. I am positive that it has a coating on the inside. So, I cut the top off and drilled my 4 vent holes in the bottom. I have now LOADED it full of twigs and logs to do my burn out. I have not purchased a torch yet so that was not an option. Do you think that this fire will be sufficient? Do I need to make sure that all the paint on the.exterior burns off to ensure the inside is clean? Thanks!
