Re: Rebuilt Flathead Problems.
I recall that consensus here is to drill 3/16ths.
The johnsons are fairly stiff to crack and turn.
I feel more secure with a 3/16ths hole and the biggest allen key that will fit in.
I think an allen key that would fit thru a 1/8th hole would cause a bit of sweating at maybe breaking off.
Although , it is your call.
