The coal feeder looks like a stumps and it sounds like a stumps. Wonder if its a clone? I am a member on another site Prairie something, and stump himself is a member there. He has offered help hints and tips to anyone wanting to build a clone stumps. He only ask that anyone that builds one pls dont try to sell it as a stumps. I thought that was very cool of him. He also has ask for any ideas and suggestions to improve on his smokers.
