After building a frame for 11 weeks there is always something that can still be cleaned up or added. You just have to take a few steps back and say when is when. I don't build a full frame in 11 weeks straight on a project of this size. I jump between the sheetmetal work and frame work, because in some cases I get fabricater's block, just like writers get writer's block. As much as you want to finish the project you don’t want to look back and say, "should've, would've, could've". So it's best for me to just take my time and be methodical about every individual piece.
