We want to skip ahead on our R&D skimmer build, to talk about a concept we wanted to try. We had this idea of creating a multi-density foam skim board, not like on a surf style board with a low density core material, but with a normal higher density core and then an even HIGHER density skin on the deck side, thermoformed over the rails and bonded over the entire surface.
Our thought was that we could improve the durability of the deck side where most heel dents and the like occur, plus by wrapping the skin over the rails where it would curve, we could increase the stiffness our along the rails. We’ve talked about how “grab rails” are actually a means of stiffening the rail out along the perimeter similar in function to the folds and indentations on your cars door skins.
So…we didn’t do that! We’re sorry! We had PLANNED to, but never got around to buying the material and supplies we would have needed to make that deck skin. Part of the planning for that build, was that the remainder of the core is about 1/8″ thinner than the final overall thickness that we wanted to achieve. So we had to add something to structure to get it back up to the thickness we want. We opted out of the more difficult wrapping the rails, since we are going to be using the same density material for this skin, as the rest of the core. So wrapping would have just increased the complexity without really giving us a true test of the increase in stiffness out along the rails due to the wrapping. So, instead we will just glue the skin to the bottom and call it good.
We want to go off on a tangent for a moment. There are, in our minds, six sort of pillars of ethical behavior: Trustworthiness, Respect, Responsibility, Fairness, Caring and Citizenship. We are pretty sure that most folks would agree that ethical behaviors are preferred, what’s the opposite? It’s better to be unethical?! No one would publicly say that, although their behaviors may indicate otherwise. So we all sort of publicly or openly confirm: Be honest, don’t deceive, cheat or steal. Treat others with respect. Play by the rules, don’t take advantage of others. So when we show you stuff like this, where we wind up changing something because we forgot to order materials or just got impatient or lazy, we’re being straightforward. It’s not some test of how this arrangement would work compared to the deck skin arrangement, we just got lazy. There you go! So, we do that, because…well it’s easier and also, it’s honest and ethical. AND that gives you reason to trust what we are saying elsewhere. We’ve seen unethical behaviors and you simply can’t ignore them and think those folks are ethical elsewhere. If you lie, cheat, steal, mislead elsewhere, you’re pretty likely to do it everywhere. We really value your ability to trust us, so when we say we’re lazy it’s honest!!! And you can trust the rest of what we are saying, too.
Ok, so back on track.
Since we needed to increase the thickness and we didn’t want to mess with wrapping the rails on the deck side, that really only left gluing the skin to the bottom. We’re kinda hoping that adding the skin to the bottom with help the flat sheets retain some of the rocker that we’ll glue in, but as we’ve mentioned before, it really takes 3 layers of “whatever” to achieve that.
So the first thing we do is trace the outline of the core onto the skin, flush around the outline.
This skin is 3 mm divinycell H80. It’s a 5 pound density, as opposed to the 8 or 10 pound we wanted to use. It’s relatively stiff, but at this thickness cuts with a pair of scissors, somewhat like heavy construction paper.
Then we sort of match it to the outline of the core, which we haven’t shared with you as yet, but we’ve shaped the outline and also the rails.
Had we gone ahead with out original plan, we would have cut the outline 1/4″ narrower than planned, so that when we added the deck skin, the structure would have filled out to the final measurment.
Ok, so that was what we wanted to share, best laid plans, huh? We’ll most likely back up and start where we left off before this post to bring everyone up to speed. Thanks for following along and being patient with this convoluted presentation!
