Erik and Scott made me do it after looking at their other builds they finished.
Listen if I can do it so can you! All I had was a table saw, cheap drill press, Harbor freight drill and angle grinder and basic hand tools.
Just do it in little steps and get something done each day even if is drilling one hole. Make paper and cardboard templates for a test fit before cutting any tabs. Then either you or someone else can fabricate the pieces and have them welded on.
You are way ahead of the game as there are many pictures out there on how it is done. Now you also know you need a scoop for the radiator so one more part of the puzzle completed.
Just little steps and soon voila a completed Eco Exo R.
