I know there is a difference in "working in the shop" and "working on the shop". I've been cleaning mine for three weeks and I just got to the sorting and putting away part yesterday. The part I'm cleaning is only 24' X24'. The connected 24'X 36" machine shed is a whole 'nuther deal. All this junk owns me.
When you get the valve over done will you be moving on the the side covers to match?
