Joining Hull Panels

Shown to the right are Parts 1 & 2, along with 2i, which is the "butt strap".
     
Initially, I became a little confused as to which parts were numbered what.  Here they are all shown to the right.  1 & 2 are to be joined (twice), as are 5 & 6 (also twice).
     
Here, from a different angle, is another picture of the orientation of the plywood panels just before joining.
     
Parts 1, 2, and 2i are positioned.  Wax paper is placed underneath Parts 1 & 2.  Make sure 2i (the butt strap) is positioned EXACTLY between 1 and 2 (i.e., centered).  There should be a gap at both ends of the butt strap.
     
Nails will show later and leave holes to fill.  Instead use 2 2x4's and 2 clamps and join 1 & 2 together using epoxy.  Double check to make sure the butt-strap remains centered and did not "slide around" during clamping.
     
Part 6 can be identified by the "funny cut," as shown to the right:
     
Parts 5 & 6 are joined in a similar manner as 1 & 2 above - also with a butt-strap.  Make sure the orientation of 5 & 6 is correct!  It will be nearly impossible to "unjoin" them once the epoxy has cured.
     
A general word about clamping and epoxying.  When epoxying plywood together, always use un-warped pieces of large lumber (such as 2x4's).  Another trick to make sure clamping pressure is exerted along the joint is shown at the right.
     
Although not specifically listed as a step, before continuing you should " barrier coat" each of the joined panels 1-2 and 5-6, on both sides, with at least 2 coats of epoxy.  Purchase a 3 inch roller for this. 

Do NOT use the same kind of roller shown in the picture to the right.  Buy a foam roller.
     
Sand lightly between coats.  Now, continue on to the "Marking and Drilling Hull Panels" section.
