This set of DIY plans shows you how to build an offset smoker using a 120 gallon tank that is 26 inches diameter and 53 inches long from tip to tip.

This size smoker is perfect for those who are wanting to start catering or cook for larger backyard events and parties!

This set of plans features a folding smoke stack and shows using the cook chamber door safety catch!
Door safety catch parts or the plan can be purchased separately.

You can also add the patio cart plans which show a folding shelf!



If your tank is slightly longer or shorter you can still use this set of smoker plans.

These tanks do vary in length from 48 inches long to 56 inches long.

The only thing you would need to change is the width of your door cut and cooking grates to fit your tank. 



There are several ways to customize your smoker using the upgrades in the drop down menus right above the Add To Cart button!

  • CNC File: You can choose the CNC file if you plan to have your parts for your smoker cut out on a CNC plasma table!
  • Cart Plans: If you want to mount your new smoker to a patio cart this option is for you!
  • Trailer Plans: This smoker can also be mounted to a 3500 pound trailer!

120 gal offset

Plans are well sorted with great information and all parts needed with accurate dimensions. I can't wait to start this build and I might turn it into a reverse flow.
