For the cross pieces, I decided to use the miter saw with the depth stop to make the joints. It’s a simple technique, just mark as you go using a spare piece of 1×2. A faster method would be to use masking tape and attach all three cross pieces together, that way you can cut them at the same time, as well as have them be perfectly symmetrical.
I made my cross pieces longer than they needed to be, In case one of the boards didn’t fit or if anything broke. Thankfully, nothing did, but I did need to cut the excess off.
That’s all there is to it! I hope you enjoyed it and go out and make your own. If you do, don’t forget to tag me in a picture of it!
