Something for future reference and something I have done a lot of times. Coming from a metal working background I have many times tapped wood (hardwood is best) with metal cutting taps. You can then use common bolts to put things together. .25-20, .312-18, .375-16, .50-13 etc. I try and tap them quite a bit deeper than I would in steel and then use a little yellow glue at assembly. The joints really hold strong and no chance of cracking like with a wood screw cutting in.
