How do you make the best use of your pallet wood? Are there some designs that work better than others to maximize your pallet wood? Recently, I built some pallet planters and just finished a pallet raised bed. I used different designs and each design had pro's and con's on the way I could use the pallet wood.
First of all, I want to call attention to the planters I built. For reference, here is a pic...

The pro's to this first design is that you can use just about any 2X4 as the inside frame and the looks of the 2X4's don't matter because you will not see them. I just cut my 2X4's to size and screwed them together to make a lower and upper frame. Then I used pallet planks cut to 16" tall to make the sides. Simply nailed the side boards to the outside of the 2X4 frames. For aesthetics, I added the top mitered 1X4 frame. It was a very inexpensive build costing me only maybe $1 in screws and nails. Pretty fast to build, too, except I had to taper the last board on each side wall to fit. Just cut it close to finish and then I used a plane to finish off the final taper.
The con's of this type of build is that the outside side panels are each 16" tall. That left me with lots of smaller off cuts of pallet boards that will probably end up being burned. I know it would easy not to care about wasting free wood, but still, there might be a better design that results in less waste.
In fact, there is. I just finished a pallet raised bed build and the design of that build allows me to use more of my pallet planks. First, here is a picture of one side of the raised bed...

The pro's of this design is that the pallet planks are attached to the inside of this 2X4 frame. You only see what you see from the outside. All you need is to cover the space between the top, bottom, and side 2X4's. Although this frame is 16 inches high, like my planters I build before, I really only have to use pallet planks ~10 inches tall up to 16 inches tall. That allows me to use lots of planks that would be wasted on the previous pallet planter design.
Here is a look at the inside of the raised bed design, where you can see that the planks are all different lengths....

I have the raised bed sitting on a trailer, so I can move it to it's final destination, but you can see that I used pallet planks of various sizes to fill in the frame of the sidewalls. In this build, I lined the planks to the top 2X4, but even that is not required because you can't see it from the outside.
I had lots of pallet plank pieces that were 22" or 24" long. In the previous design, I would have to cut the board at exactly 16", leaving a small 6" or 8" cut off piece - too small for anything in my current plans. With the raised bed panel design, I could cut that same 22" or 24" plank in half and use all that wood with no cut off wasted. It really doesn't matter what the plank length is inside the frame because you only see the outside...

Another advantage to using this frame design is that I did not have to make any special tapered cut on the last board for each side. Because you have 2 2X4" side pieces on the frame, you have 7" of overlap on the outside. I just cut my side wall boards, laid them inside the frame, and moved them right or left to overlap the ends. Then I just nailed them in place. So, the process of making the side panels went very fast.
OK, not everything is a pro in this build. The con's I would mention are that the 2X4's used for the frame were my "better" whole uncut 2X4's from the pallets. I did not use the 2X4's with the cutouts for the forklift tongs. Another consideration is that I used pocket hole screws to build the 2X4 frames, and then I used more pocket hole screws to screw the frames into the 4X4 corner posts. I estimate that it cost me maybe about $5.00 in pocket hole screws and nails for this build.
I don't know how to build those frames on this design without using pocket hole screws. The pocket holes take time to drill out and then put together. Pocket hole screws are much more expensive than normal screws, but still, only about $5 for a 4X4 foot raised bed is not too bad.
Oh yeah, the 4X4 corner posts I used were from reclaimed lumber. So I did not get them from the pallets I broke down. Still free to me, but not technically wood from a pallet. I think it would be possible to make some 4X4 corner pieces from pallets by using two pallet 2X4's put together and cut down to size. I might try that on a future pallet raised bed build, or maybe modifying the build so it does not use the 4X4 corner pieces at all.
What I learned from the pallet planter build and the pallet raised bed designs is that each design makes use of the pallet wood in different ways. I am currently favoring the pallet raised bed design because it makes better use out of the pallet planks and I had very little waste because the boards did not have to be exactly 16" tall.
I am looking for a design that has the benefits of each type of design without the con's of either. That would be the greatest. If I find such a design, I'll let you know.
