Thanks for the tips. I had already drilled my bed-to-frame holes when I installed the bedwood last year. I mounted them with the off-set washers above wood level. So I'll have to drill with those holes already drilled through. I have a hand drill press that might do the trick. It also has a depth stop on it, so hopefully it will work. I'm not ready to do this yet, but will do it in a month or so. Thanks again for the tips.
