You should consider that you are trying to learn 3 things at once:
- how to smoke meats
- how to build a smoker
- how to manage temps in your smoker
The ability to control temps is dependent on the design of the smoker. So you should consider that it may be VERY difficult to control temps if you don't have a good design......and this is compounded if you don't know what you are doing. And it will be difficult to get better at cooking the meat if you can't control temps.
So with that said, everyone is giving you good advice to build a proven UDS design. You'll learn to control temps AND learn to smoke great BBQ. If you build a wildcat design.......well, it could be the best thing since sliced bread.......or more likely, set back your progress as a BBQ chef and be a source of great frustration.
Keep in mind the cutting a door is a potential source for air leaks.......which cause out of control temps in your pit.....,
