Dan has a great space off his garage to work on the plane. He installed a tarp as a divider from the garage and an electric heater should help with the Minnesota winters.
The work space we have is a area that is 14′ x 22′. It is part of a larger garage where we have a compressor as well as where we keep the aforementioned material rack. No matter how much space you have you’ll almost always want more (or use more). Kind of like the old saying, ” expenses always rise to meet income and the tools you own always just fit in the garage space you have available.” This may be a bit simplistic but it seems to hold a lot of truth.
The space we have is heated, although not continuously. We only turn the heat on when working. I’ve done projects in the back part of the garage in the winter when it’s been really cold out (like -10 F) and not found it at all difficult to warm the area to a comfortable 60 F in a short time. The walls are insulated with foam, one wall is common to the house and the ceiling is insulated with plenty of fiberglass (maybe R30 or something like that).
The work table is a 4′ x 12′ work space and it is on rollers so it can be moved from one side of the room to the other when needed (like when we roll in the storage rack to load a new sheet of aluminum to the table for cutting). The table and the rack are two very useful additions to the shop. They were definitely worth the time it took to build. I’ll add the drawings for the rack but I kind of made up the table as I built it so I’d have to try to re-create the design from the photos I have of it.
