Hi guys, here's a link to some pics!

1/2 hardwood plywood, 1/4-20 bolts for everything except screws, which were mostly #10 and a few #14s.
It took a LONG TIME, since I had to make two of them, my workshop is a disaster area (it really slows you down when your shop is messy!) and of course, I only had a few half day weekend days and a many after-kids-go-to-sleep hours to work on it. I think if I had 3 sold workshop days I could have done it a lot faster...well especially now that I have two of them under my belt.
My brother has hinted that his son needs one, but he's only 6 months old, so I have a full 2 years or so to make one for him!
