A while back there was some discussion about making a drill longer than currently available. I made this one 40 years ago. I had never seen a wood tip on a drill in any store I had ever been in. Not sure if there were any WW specialty stores or not. Never thought about it. Lumber yards and hardware stores were my world.
It is a 3/8 inch x 12 drill bit. I held it in a vise on a drill press to drill a ¼” hole in the end. I used a 5” piece of ¼” drill rod for the extension. Soft solder was used for the joint.
To get the wood boring tip that would run true in curly maple, I hand ground it on the corner of a grinding wheel.
