#115 Bit - Cut-A-Way of  Potted Deck Hole

#115 Bit - Cut-A-Way of Potted Deck Hole

This is the cut-a-way of the hole I cored out with the #115 bit. If you'll notice the epoxy potting is a little thicker than with the #654 bit. I don't feel this serves much of a purpose, & both will seal the deck from future moisture, but does require slightly more work in the over sizing of the top hole to 5/16" or what ever size you choose.

When you re-drill your holes, after filling them with epoxy, try and do a better job than I did of centering your bit over the original hole or your deck hardware might not line up again.

This re-drilled hole is off set to the left a little bit. Please be careful when drilling over sized holes as it makes re-drilling that much more difficult. When in doubt mark the center points of all your holes using the deck hardware as a template.

One additional step I use is to drill and run a tap through the hole based on matching the bolt/screw thread. This will ensure any water that makes it's way through from the top will not makes it way through the thread.

One thing you could do to help align the redrill holes would be to mark centerlines on tape beyond the tape that keeps the surface epoxy-free. For a given hole, four pieces of tape to mark two right-angle centerlines. When ready to redrill, use a straightedge to mark the intersection of the centerlines at the center of the original hole.
