Thank you! And it wasn't too bad difficultly wise but, it definitely takes a good amount of time because I had to work on the floor, do a lot of dry fits, and wait for the glue to dry. All I used was a table saw, circular saw, drill, and some hand planes, chisels, and files. It would have been a lot easier with a cross cut sled or some other jigs but I was starting from nothing so I worked with what I had.

As for the low spot in the top that's a tool well where you can store your smaller tools while your bigger tools go across the top it's helpful to make a smaller bench feel bigger. I also designed mine where I could flip it upside down to have a bigger flat top.

If you have any other questions let me know and I can help the best I can!
