Wow, all this modern stuff. Last time I saw a drafting table was probably 1979, and not near as fancy as all those. A whole lot simpler, but worked just as well. Actually, once the were angled, they were never moved again, so can't really see the need for all the fancy (expensive) hardware. If I were making one I'd just drill holes on each side, and bolt them in place. Then if I ever wanted to adjust it, drill new holes. move it, bolt it.

Of course I'm not busy, I did it right the first time.
Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
