Here is an Easy DIY project you can do in a weekend. Not only is it easy, you can get a high quality ceramic smoker without the cost. Compared to the cost of the Big Green Egg, this is an effective alternative.
Start with a few washers for each side of the lid. The lid comes with a hole pre-drilled. You will need the bigger washer to cover the hole and the washer with the small hole to keep the knob lined up.
With a trip to you local hardware store (Home Depot or Lowe’s) you can get almost everything you need to complete this easy DIY Project for around 50 dollars.
NECESSARY SUPPLY LIST:

Once you have all of the required items, it is just a matter of putting it together. The basic version (without accessories) is just a matter of putting the Proctor Silex hot plate in the bottom of the pot with the cord being fed through the existing hole in the bottom center.
Second, place the grate in the pot. The grate may needed to be rotated in order to find the right balance but it fits almost perfect.
-Grab a heavy duty metal round pan, fill with wood chips, place it on the burner, set the temp to High and watch the smoker do its thing.
