All three booths:
-  No welder shelf
-  L shaped table with the 30” L protrusion along the left wall. (refer to attached image)  The width of the protrusion should be 13”.
-  Support gussets for the table (marked "stif")
-  Add a 1” welder conduit.  If this will not fit with the existing conduit, it can go outside.  Please advise how you feel it would best fit.
-  The 1” conduit should come below the other conduit, to just above the table top as indicated by the red dot in the attached picture.
