I just cannot believe how many people will do ANYTHING to avoid spending
$50 for some epoxy. Enough 1/4" clear cedar strip for a decent size dinghy or canoe will cost you at least $500.00. Do you really want to risk that investment and your labor to save $40 or $50? The strips are not there just to hold the glass. They provide longitudinal stiffness. They must transfer shear loads between the two composite skins. And they must spread impact loads. Individual strips are not capable of doing any of those things. They have to be well bonded together so they can act in unison. Hot melt glue is not going to that. Liquid Nails might hold the strips together but the assembly will not be very stiff and fairing will be a royal PITA. You need a glue that maintains a tight stiff bond in a varying width glue line (gap filling), does not require high clamping pressure and that can be sanded fair without gumming up the paper. There is only one glue commonly available to amateur boat builders that will do that: Epoxy. Thickened epoxy is gap filling, bonds extremely well, requires minimal clamping pressure so staples are all that is needed and it fairs cleanly. Resorcinol would be a second choice. It would be a little less costly but requires careful fitting to eliminate any gaps and a lot of clamping pressure. Staples will not do it. You could only add one strip to each side per day. Same with polyurethanes only your total cost will be more than epoxy. There are people on this newsgroup that will advocate anything from wallpaper paste to curtain liner to save money but trying to save $50 on adheasive on a $700 project is penny wise and pound foolish.

I would like my next boat project to be a cedar strip row/power boat and the John Clark plans look Ok on the web, but they seem a bit expensive for what are essentially a set of hull templates. Also, can anybody advise on what type(s) of glue are suitable for cedar strip construction. Builders adhesive has been suggested. Here in Australia the "Liquid Nails" product is sometimes referred to as builders glue. Does anyone know whether this is the same product? I would prefer to build without fasteners if possible, so any experience out there would be appreciated. Many thanks. Ken -- Glenn Ashmore I'm building a 45' cutter in strip/composite.
