All in all, it only took about 10 hours (high balling) to make. I used just regular construction lumber, cut them accordingly, and used glue and screws to hold together. This was my first big DIY project, and I’m really happy with the results. The base diagram does need additional measurements for where the primary support beams go, so I did mess that up. But it’s stable, supportive, and VERY HEAVY!! Thank you for the step by step instructions.
