Using Jigs for Faster, Accurate, and Repeatable Builds

I have mentioned that the stackable compost bin system I built a year or so ago has proven to be more valuable to me than I had anticipated. I decided to build another pallet wood compost tower of stackable tiers.
Here is the basic idea of the stackable tiers...
My changes for my pallet wood stackable compost bins are that the inside measurements are 36X36 inches, and the legs have a gap of 1-1/2 inches on top and stick out 2-1/2 inches below the frame. I also taper my legs so they stack easier.
As I previously mentioned, I wanted to use my new air stapler instead of using my normal drywall screws. Using the air stapler is much faster than drilling holes for the screws and then drilling each and every screw into the wood. And yes, since I was attaching the pallet wood using end grain or the end of the boards, I had to predrill my holes for the screws or risk splitting the wood. Using staples bypasses all that concern. Just point and shoot. Very fast. No wood splitting.
As we all know, pallet wood planks can have all kinds of widths and thicknesses. Because of that, I had to redesign the build which originally used standard 1X6 pine boards. The original plans all used outside measurements because the 1X6 wood was all standard thickness. But I had to reverse the design to accommodate using pallet wood planks of different thicknesses. I had to build my stackable compost tiers using inside measurements; therefore, the various thicknesses of the boards did not matter.

My goal on this new build was to come up with a system that used my air stapler only and that I could more easily, and accurately, put the frames together. Long story short, I had to change the way I built the stackable tiers. It took me a few days to think of a couple of jigs I could make to assist in my build.
Here is a picture of my two main jigs that I came up with...
The jig on the left is used to attach the legs to my boards. More on that a bit later.
The jig on the right is just a board cut to 36 inches. My stackable tiers measure 36X36 inches on the inside, so I just use that 36-inch jig board space out the frame exactly, no need to measure anything and slow me down.
The old way I put together the frames and the legs, using screws, did not work when I used the air stapler. I came up with a solution with that jig on the left. I simply put my tapered legs on the jig and then place the board on top. There is a block of wood that creates a 1-1/2 inch gap in the top of the frame for the stacking legs.
So, I just put the tapered leg into the jig...
And then place the pallet plank on top of the leg...
That allows me to shoot the staples down into the wood and legs nice and solid. Before, using my old system, I had to use clamps on the legs but the power of shooting the stapes into the leg would sometimes push the leg away from the corner - misaligning the legs - which are needed to be correct for stacking the tiers. Shooting the staples down into the legs this way fixed that problem. Plus, I no longer have to setup clamps for that step which saves me a lot of time.
I figured out how to make the tapered legs, cutting them on my miter saw using a stop block and a ~7 degree angled cut on 2 faces of the leg. That slight angle on the legs allows me to more easily stack the tiers. Yes, it will work even if you don't taper those legs, but more often than not you will have to tap the legs in when stacking the tiers. With the tapered legs, you don't have that problem at all.
Here is a picture of my new stackable pallet wood compost bin tower made with my new jigs. There is a learning curve on any project, but I would estimate that using these jigs makes my build time about 5X faster, more accurate, and easier to repeat.

Of course, it only took me about a week thinking of how to make these jigs and put them to use. It took me about an hour today to build the jigs, with a few adjustments and tweaks before everything worked. And by the time I learned how to get my workflow working great, this project was over.

Considering the time and effort I put into making these jigs and learning how to make the stackable tiers in a different way, I might just build a few more stackable tiers for extras. I think I got the system down now and I have lots of pallet wood to use up.

I'm just an old guy trying to learn some new tricks. Building and using jigs was just another skill I wanted to improve. Jigs sure make the build more accurate, faster, and repeatable when you get them right.
