Bought an old New Braunfels Black Diamond last Friday (for $20) and spent last weekend sanding, grinding and painting. Read up here in the forums to get an idea how to operate it and what mods to make. I added a deflector and lowered the smoke stack. I still need to add grill level thermostats. I did my first ever run today, (just finished eating) and my NBBD ran at 220-230 all day with very few adjustments from me.
