I received an e-mail asking me about panel boxes, did I have them and what kind? I have a bunch of them. None are however, the new vinyl and foam light weight store-bought kind.Those are good and light, but I want armor, not portability so I make my own. Also, since I work larger than many of the plein air painters, the available boxes are often not large enough for my needs. I have had the box below for many years and it holds 18 by 24's. It is luan plywood and pine held together by sheet rock screws. It is functional, heavy and ugly. This would never do for air travel, they live in the trunk of the car, I never carry a panel box with me out into the field. I have had most of my panel boxes longer than the new vinyl jobs have been made and I like the utilitarian crate look, but I would like to have a smaller vinyl one as they are light and good for travel.
Here is the slotted inside of the box, I cut the slots on my cheapo Sears table saw. There is a door hinge at the distal end of that lid I am lifting.
Here is a sash lock, that holds the box closed.
Here are a couple of shots of a box made for me by a carpenter, the top slides in a groove and this holds 9by 12's. It ought to have a handle though, or a strap.
Here is a really easy to make and soundly utilitarian box given me by a friend. It is made of rigid Styrofoam insulation joined with duck tape. Below with construction glued spacers in it's interior to keep the panels from mating. This 16 by 20 box is light. It has no lid and is again, something that lives in the trunk of my car. This thing will hold a lot of panels two to a slot and then maybe a few more crammed in there too. Ideal for a painting trip.
