This little thing was something I doodled in the corner of a random piece of paper, and the idea of an alien anteater took hold and got it done.
The whole drawing was done in Photoshop and Painter; Photoshop for the lineart and shading, Painter for the bulk of the rendering.
For those curious about the process, here are a few notes about it -
-Drew the lineart in with something close to 80-90% grey. Once it was done, I adjusted the hue/saturation on it to make it a dark red-orange color, which blends better than if it was just the grey line (got this little tidbit of information from watching a Carlo Arellano workshop.)
-In Painter, I didn't do a monochromatic underpainting (though on reflection I probably should.) Instead, I took the New Simple Watercolor brush and roughly laid in my colors that way (I also tried to place value in at the same time, and it didn't work out - more on that later.)
-From there, I took a new layer and started to render it out bit by bit. The bulk of this work was done with the oil round and the chunky oil pastel brush
-After I finished rendering, I realized that the drawing was overall very flat. So I took it into photoshop, and created a photofilter layer (under the same tab as levels, curves, hue/saturation, etc.) I gave it a warm overlay, and using a layer mask started to carve into the drawing, creating the shadows.
In the end I had to resort to cel-shading to take it away from looking flat - not my original intent, but it suites it fine.

First, we need to attach the tee nut. The tee nut is what we'll be using to attach the pochade box to any standard camera tripod. I took a spare piece of wood I cut out, and after finding the center of it, drilled a hole that was just a bit bigger than a 1/4" in diameter. I then took my rubber mallet, and started to bang the tee nut down into the hole (For some reason, the nut was extremely difficult to get in there. But a tight fit will ensure it stays.)
Once you find the center of the bottom box, attach your tee nut piece with some wood glue and once it's dry you can continue assembling the rest of the box.
The next thing to do is to reinforce the boxes – you’ll put an L-bracket in each corner of both boxes, to reinforce the sides, as well as attach a few to the bottom and sides of the bottom box. Since the plywood can splinter easily and the screws I used were made some of ludicrously soft metal, I’d advise to pre-drill the holes a bit.
From there, I attached the hinges. My hinges are placed oddly because I thought two would suffice, when in fact I need a third to steady the open/close action. Again, pre-drill your holes.
Now it’s time to install the turnbuckles. Without these, the box would just flop open, and I wouldn’t be able to adjust the angle of the top half.
The construction is fairly simple. We’re going to drill ¼” holes about 2 ¼” in from the edge of the box on either side of both halves. Refer to the pictures to get a general idea of where this is going.
Once we’ve done that, it’s time to install the bolts, which the turnbuckles will hang off of. Since space is at a premium on the side, the bolts will face outwards. It’ll be a tight fit, so some elbow grease will be required, but you’ll soon have them in.
If you notice in the picture, the turnbuckles can be removed by simply unscrewing the nut off the bolt and slipping the turnbuckle off. To adjust the box, you don’t even need to do that – twisting the middle part of the turnbuckle left or right will lengthen or shorten it, affecting the angle of your box.
And with that, the construction is complete! I still haven’t found a suitable clasp to hold the two halves together while traveling, so at the moment I’m using an old woven belt.
For the trays, I’m using an old breathmint tin with a binder clip to hold it to the side. It won’t hold my brushes at the moment, but it’s the perfect size to hold my water cups.

In part 2 of this series, I went over gathering supplies and drawing out the plans. Now it’s time to cut and build those boxes!
There were two main goals I was after while cutting out the pieces: Straight cuts, and clean cuts. I thought at first I could use a hacksaw to get through them, but it was a lot of work with very little return.
Enter the jigsaw! Using a jigsaw, I was able to cut up the pieces quickly. A few words of caution when using the jigsaw to cut out your pieces:
-Always wear protective goggles (this should be extremely obvious.)
-Be sure to secure your wood to a worktable or whatever it is you’ll be cutting over. I used a stack of weighted milkcrates and clamps to secure the plywood while I was cutting.
-Don’t rush through your cuts! This can lead to rough and poor cuts, and you’ll end up with pieces you can’t use (as I found out a few times.) Take your time, and make sure you’re cutting along your measurements.
In the end, you’ll have all your pieces cut out and hopefully straight, like above. If you need to, sand the sides a bit to get rid of splinters.
Now, at the time I wasn’t able to seal my box with shellac or what-have-you. I would recommend it though, as it’ll help protect your box against the elements. Ideally, you would do this after you pre-drilled the holes for the screws, so you would probably have to test fit your box first, then remove all the hardware, seal the wood, then reassemble once dry.
Since I didn’t do this step though, I can’t provide much beyond that, so we’ll move on to the actual construction of the box.
The sides of the box are not going to be sitting on the bottom of the box – instead, we’ll be putting them on the edge of the box.
Also, the approach we’re taking to assemble the sides involves each side overlapping the previous one. Hopefully the diagram explains this better than words. Believe me when I say this is a stronger design than having two sides nestled between two other sides.
To start, I decided to assemble each side one at a time. We’ll need the brad nails and wood glue for this. Apply a layer (not too thick!) of wood glue to the edge of the box bottom, then butt the side of the box side up against it. You’ll have to hold it for a few minutes, and if you have a clamp system that can do this, great, you’ll need one less person down the road.
After about 2-3 minutes, the glue will have dried enough that you can hammer in the brad nails to firmly secure it the bottom and the side together. You’ll probably need another person to hold the pieces together while you hammer them, though. I used two brads for to attach each side to the bottom, and one to two brads to secure the sides to each other.
Be sure to not do this part hastily! The wood is thin enough that if you aren’t careful about the direction the brad nail is going in, you’ll easily end up splitting the wood or finding it sticking out one of the sides. So BE CAREFUL.
Once you have one side done, congratulations! You’ve pretty much figured out how to do the remainder of the two box halves. Just repeat you’re steps for the remaining sides.
After that, you’ll have two box halves assembled! In the final post, we’ll go over attaching all the hardware and assembling your box for outdoor painting.
