hey guys, just finished a build and found that the neck is bowing, i made the neck out of tasmanian oak with a maple frett board, strait through neck, i normally glue the neck to the lid, this time i srewed the neck down to a block inside top and tail, i never had this problem before, ANY TRICKS ANYONE?

Sam ...anytime you see a wood with a state of Australia as a prefix, tassie oak, qld walnut Vic ash etcetc it's not the real one but something that looks like it, what the first white woodworkers called em when they came across 200 years ago :)
Kid,
OK, thanks, ... unless it has properties like a wet noodle or that CBG has more than 4 strings, it ought to had moderate tunings on a CBG. Adding a fretboard would stiffen up what ever it is. I've had perfectly stable 4 stringers with 1x2 poplar necks (3/4 X 1 1/2) and no additional fretboard. Poplar is not a strong wood at all compared to oak, maple etc.
the best,

Hey guys, thanks for all the comments. i have been away for a week without computer, just got back, what i did before i left was i glued a block a few mm thicker than the block at tail and fretboard end and because i left room between the lid and the throu neck in the hope for better sound' there was room for it to bend, i discovered that the neck was strait but it was bowing at the point where the neck goes through the box, this done the trick, so i just checked again now and it's still strait. fingers crossed!!.
Since the neck is removable, why not take it out, add a fret board, level it and reinstall it. The fretboard will add strength and then all you will have to do is add a taller bridge.....
Unless you have a very thin neck or are using heavy strings on a six stringer, an oak neck should have been strong enough. It may have been slightly bowed before you added the string tension....
hope this helps,

That's a good solution.
Or just tune down a step.
Had this only once, because I made the neck too thin. It was a pain but I routed out the back of the neck, put in a truss rod from a junker acoustic, covered with rosewood and reshaped it.
