guys, i don't want to go insulting people.... but ah.... that stewmac info sheet shows u exactly what u need.... and has one of those pictures where everything is connected with dotty lines, what more do u want? like a fisher price guide to making ur own neck jig? We're not dealing with lego's anymore guys (unfortunetly ) i just don't understand exactly what more u could need? Is some of the hardware hard to get? I'm just taking a breif look at it, and there aren't to many measurements there, but it doesn't take a rocket scientist to figure out that u'r going to need a "beam" about 4 feet long, and a board wide enought to hold an accoustic. As for the threaded holes, u can buy those things at canadian tire (home depot, kent, or what ever in the states) drill ur wholes and i beleive they can be pressed in with a hammer, or with an allen key oposite the way the screws would go into them.
Maybe i'm missing something really obvious here ?
