I looked at several videos on making your own coping sled. Some elaborate and some super simple. I wanted something repeatable but not overly complicated. I found one really good sled build, but found the parts were going to be $48 with shipping, not including the time to accurately cut and build. I found this Rockler Coping Sled on sale for $60, and figured that $12 would be worth my time of building my own.

Overall, I'm happy with the sled. Had a couple issues with the build which I cover in the video. It worked great for building a few cabinet doors, and is a new keeper for my shop.
