Great design. I've made a couple of wooden ones in the past too. What are the dimensions of yours and why is there casters on only one end? I'm thinking you can pick it up by the other end and roll it around the shop.
Sometimes the easy button is the best. Post some pics of the interior when you get that finished. My suggestion is make it flexible ....... working in smaller spaces often leads to rearrangement of that "perfect" layout.
New to GJ but not to motorcycles. I've had several and probably close to 10 projects underway right now. I'll be putting up a new workshop soon and will post pics along the way. However, I've outgrown my current air compressor both in overall volume and CFM. I'm looking at different units...
