I need to drill a couple of holes to screw a 1/4" hanger bolt into the
heel of the neck (jatoba) so I can bolt it onto the pot/rim (also
jatoba) I turned on the lathe. I'm wondering what size drill bit to
use, something around 7/16" fit the bill, or that too big? I'm only
getting one shot at it else the neck for the banjo I'm making is toast
and I don't wanna screw it up at the last minute...
Also wondering if, before screwing in the hanger bolt, soaking the
drilled holes with oil would make the wood stronger?
Graciously looking forward to a hint or two,
Bart.

clearance(?) hole for a wood screw should be the same as the
root diameterbetween the threads of the screw

I doubt any kind of surface treatment coul make the wood
appreciably stronger
