Hi all. I used this forum to build my first UDS years ago. Its been good to me but i might need another project. Stumbled upon the brick smoker section and a light bulb went off. I bought the house I'm in 6 years ago and have been struggling with what to do with the built in grill area. I have been using it as a charcoal griller but without a lid, my grills haven't been ideal. Here is a pic of the spot. The hose was built in the 60's with slump block. The cove is lined with firebrick. It vents up to the top of the roof. All looks in good condition.. The existing width is 28 inches and can't really get any wider. Its 21 inches deep tapered to 17 inches at the top. Again, not much I can do. Its 41 inches tall right now. I could remove 1 course of block and make it 45 inches or 2 would make it 49.5. I have read the other build threads and think I could get a frame and door(s) fabricated. Do you think I have enough to work with? I'm a little unsure about how tall I should make it. My UDS is smaller than what I have right now so I think it can be done.. Here is a pic looking up at the top vent. I know it has a proper name, but since I live in Arizona, we are not all to familiar with fireplace anatomy...I am thinking of just keeping this always open and fabricating another top vent that has better, ie easier adjustment. Any thoughts?
