Thanks for the link. I may think about this someday. I do some woodworking and have an olympic barbell set. I built a weight tree for it out of 2x4s and pipe nipples that works pretty good.
I’m not sure I understand your question though. If you you’re questioning if you can build it, maybe it’s not the project for you. You’ll need a drill, appropriate size bits, circular saw, screw driver (or bit for the drill). Having a table saw or mitre saw would help in cutting the angle for the braces.
As for cost of materials, geez, the site gives you free plans with a BOM (bill of materials). Go to your local home depot / hardware store and price them out. They claim < $150.
I know for sure I could build this. With out a doubt. I am just wondering when I put some heavy ass weight on it if it will hold. Second how much the wood is. Its not like I buy wood all the time.
What about using thicker support posts. Then you would not have to glue and bolt together 2x6’s. The only thing I can think that might happen is the post might crack if you dropped the weight at 500+ lbs[/quote]
I am in construction and also an engineer.
Yes, this will hold and yes it will work great.
My only concern is the pins, either a short solid shaft, or thick wall hollow. Many people think that solid bars are strong, but in fact they will bend much easier than hollow ones if longer.
Edit: As tedro said, pins should be solid shaft, but the longer the bar the easier it can bend. If you have a 5’-6 long piece, you should be fine, anything longer find either an 1" or bigger.
