Norcoredneck, you built a cool UDS smoker! I'm interested in making one. Would you clarify some details for me? I see there are two sizes of BDS fire grates on their website. What are the specs for the large grate ring and base and small ash grate ring and base? What size bolts to attach the fire grate parts? In the side of the barrel what size bolts are used to hold the grate up? Does it matter how far the holes in the lid are from the edge? Thanks!
