One of my commenter’s, Scottiebill, sent me this tip:
“…Predrilling screw holes with a countersink bit is vital. However, it is also wise to countersink a little bit on the opposite side of the hole to allow someplace for the wood that is inevitably pulled up by the screw to go. If this is not done, odds are that you won’t get a tight joint, that there will be a slight gap between the two pieces you are assembling.”
Honestly, I have never thought about this. It sounds like an awesome tip. I would guess this would be especially true if you are doing fine woodworking with hardwoods like oak and maple and several of the tropical varieties.
As always, I welcome comments. If you have any advice for other woodworkers out there, please let me know. I will provide full attribution.
