Ben, I just built mine a couple of weeks ago. I crimped the top edge down. I took the finger from an old leather work glove wrapped over the edge and a vise grip pliers to it. Made quick work of it. Probably had the whole rim done in under 5 minutes.
Todd, my wife is wishing it hadn't happened. She doesn't understand why I needed another cooker. I have the 22" WSM already. But I love building things. And I like that this is more portable. I'm taking the Mini ice fishing on Mille Lacs Lake MN in February. can't wait to smoke, while drinking...
First of all I want to say thank you for all of your great posts and thoughts on how to build this mini.
Secondly let me apologize because I suck and I didn't take any pics. I know, lame post. But remember the first part. Thanks everyone.
