Draining skiff hull - need electrician's bit

I see the picture of pipe nipples, what diameter pipe did you use? I may try this on my old Mckee, it seems to be losing speed. Thanks

You can’t catch fish on a dry line

The black steel pipe was just used to weld the drill bit to the 3/8" rebar, so 3/8" pipe was perfect. The true value in Moncks Vegas only had 6" lengths but a 10" length would have made it easier to make sure the drill bit was lined up straight with the rebar. Turned out fine anyway.

You’re welcome to just pick mine up if you don’t feel like welding your own.
