Does anyone in the industry know what glue clark used to glue up stringers? I’ve used a two part epoxy that sets too slowly and have had some trouble with the epoxy being a bit too brittle / hard that it dulls my hand planers. Best suggestions, what brand, where to buy, who to contact? Aloha from hawaii
BRAH-------------- Try your normal polyester resin with the color of your choice: red, black, blue or clear. McDing
Right on. What better way to glue up a stringer than with customer color.
Thanks guys, but the regular polyester resin is way more brittle and hard than the actual clark glue – its hitting the blades on my hand planer and dulling it. Clark glue was not like that – i know i was a polyester base but it is definitely softer after it is set. any one else know?
Polyester Lam----not sanding or finish.
I have watched the glue-up process at Bennett and Ocean Foam here in Aust, and the stringer glue was merely normal resin, with Q-cell…

McDing, has told you true. Follow his advice.
I’d listen to the guys who have shaped hundreds to 30,000 Clark blanks…
Poly lam with pigment or tint, sometimes with additives…
Clark custom mixed his glue for temperature, fast in the AM and slow in the afternoon. It was a basic lam resin with a lot of additives, a lot of em.
How many additives can you put in lam resin anyway? Perhaps you experts can clue me since Clark is no longer in business and his secret glue formula should be of little consequence. The only malfunction with swaylocks is the anal “overkill”. McDing
I’ve heard him say right from his mouth, “Lam resin, the cheapest, worst resin you can get your hands on…” Didn’t ask about additives but it sounded like just straight lam (SBS may be able to specify) with some neutral pigment, or colored pigment when custom-ordered.
FWIW: I hope future blank makers will step out of the Styrene-based mold and try some of the water-based urethanes. I’ve already seen some groups meeting success with these non-polluting, low-toxicity glues. Look for UV stable formulations…
Good News, Just Foam is not using stryene of anykind in our glue. Grubby gave me a couple of drums of his glue when he shut down. He also agreed to give me the formula but I was already using something I considered better so I passed. I can tell you it did not last long because of the catalyst he used, he made one batch pretty fast.
