Absolutely correct with the trick to a successful restoration being convenience. Most of us have to operate in a small garage at home. Anything you can do to make that small space work for you over a long period of time is key. If not you’ll loose interest as too much time is spent setting up every day. I’ve done restorations in garages I’ve owned from a single to my current triple. Keeping organized is so important. Can stress it enough.
Great idea but have you priced wood needed to build this lately? I think they're even charging for used wood. Just being facetious. But seriously, wood pallets with casters might also be an option. They come in various sizes & capacities and are quite often free from businesses that receive bulk shipments.
