I need a 1/2" or so hole drilled down the middle of a not installed pressure treated 6x6.
I tried drilling a perfect 1/4" hole through a hard wood chunk of 4x4, then screwing this onto the properly cut off end of the 6x6 and using it as a guide for a two foot long continuous 1/4" bit. Then a long flexible 1/4" bit, watching to make sure the smaller rod was centered in the hole.
Came out on the side, just close to the end!
I suspect the flexible drill bit wandered according to grain or whatever.
I need a pilot hole so I can then use a hole hawg and put a three inch hole down the middle.
My next idea is to make a long half inch bit using drill rod, and monitor it's angle closely.
Any thoughts?
