Here is the site he found it on. You can buy plans, but he is going to work it out himself. The only problem is probably the lever thingie that moves up and down. Chances are we will have to buy that eventually :)

He is very handy. I just happened to luck out. He can cook, fix cars, is known to do laundry and made our kitchen island. :)
