Nice work. I would have thought that you would make the office in a corner where you only needed two walls and have the outside Man door enter into the office.
Do you have a floor plan for your build that you could share with us? I would be very interested in how you have planned the layout of office, equipment, segmentation of machine area, welding, grinding, compressor, etc.
I hope to have sufficient room for me to separate the Machining (Mill, Lathe, etc) Area, Welding/Grinding Area, Office Area, Reloading/Gunsmithing Area, Auto Work Maintenance Area and Storage Area (Pallet Racks, RV, etc). Some of these areas will no doubt overlap and may be smaller than I might like.
Have some rough ideas for layout but always looking for new ideas.
So glad to see you nearing the light at the end of the tunnel.
