I made stall bars too!

Now: important things.
Here's a list of things to do/not do when embarking on this journey yourself...
1) If you use 2x6's for the uprights make sure that you'll have enough room for your fingers between the bars and the wall when you're drilling the holes.
2) Don't hang the bars backwards because you're too excited to play on them. ![]()
3) Spend a little more money for good hardwood dowels (mine are Oak dowels) because do you really want to trust fur/pine to hold you inverted or sideways?
4) Don't snap off screw heads inside the sides of the dowels because they tend to free-spin.
5) I'd say 1 more dowel would be nice on my setup - I have 12 with 11 of them every 6 inches on the bottom. a 12th would be nice down there.
6) A Forstner bit will do the trick nicely for drilling the dowel holes with an 18v cordless drill.
7) One battery on said 18v cordless drill will only last you about 1/2way through the job. Have a second battery or some serious patience. Or a drill with a chord!
Oh and as far as measuring for consistent drill-hole depth: Just draw a line around one of the dowels and put it in there after drilling to make sure it's deep enough! (make sure not to go too deep!)
That's it! I'm going to have to take them down and flip them over in the coming week. Darn!
