I just ordered Great Auk kayak plans and read Nick’s book, “The Strip-Built Sea Kayak” as first steps. I also ordered a 2x4x16 foot LVL construction beam to use as the strong back (I read that this was a better option than a 2x4 because it is more true). My naive question is how I attach the forms with actual 2” by 4” cutouts to the LVL, which has 1 1/2” by 3 1/2” true dimensions. Should I try to center a 1.5 x 3.5 inch hole on the form instead of cutout the 2x4 hole, or just try to shim the larger hole to the smaller LVL? Also, should I screw the forms to the LVL, or is it better to make box spacers to space the forms and hold them in place. I’m sorry if this is an old question. I did a search and couldn’t find the answer. Thank you for your help and any other advice you can offer. This seems like an impossible project looking forward from the beginning.
