I'm making a bed with the main frame made from 7cm square lengths of pine. In several places, one of these will be secured to another using wingnuts and 10mm bolts going through two adjacent blocks. (The bed will be heavy but quickly dismantlable). Has someone got some tips for avoiding splintering the back of the timber when drilling the holes? What kind of drill bit should I use - brad point, auger, paddle, holesaw?
Thanks!
