ATTACHING DECK PLANK USING LAP JOINT

Post by Shawn K » Mon Nov 18, 2019 12:51 pm

If im understanding everything correctly , im too use a lap joint on all my deck beams in my frames with the deck beam mounting on the forward side of the boat. well thats how I've been doing it and thats what my plans seem to be calling for. So heres my question, in the book building with plywood, it says to use carriage bolts to attach the deck beams to the side beams as well as epoxy but now I see where my fastening schedule says to use 2" #10 screws. What to do ? what to do? or am I missing something or maybe overlooked something? HELP!

Shaun,

Lap Joints - yes.

The book on plywood construction is a great general guide. For specifics, see the plans and instructions. Check your instructions/Fastener Schedule - 2" #10, 2/junction. (I would reduce the length if you're not using a full inch/member)

See sheet 2 for location of deck beams - Frames 6 & 7 are aft.
