Hey hands each fin is about 75cm^2. This surface area is similar to extra small 4ks (4way fin system) fin. The base is similar too. I pushed them back to compensate for the forward sweep of the trailing fins. But as far as concrete numbers I’m in the dark. So I’m hoping that someone who has tried this before will weigh in…
I’m just going to glass these on. It’s too much work adding structurally sound tabs to the fins (read no skill haha). If it don’t work, oh well…I have an angle grinder. Cheers for tunning in…
Congratulations! For me, getting the thesis written was the biggest hurtle. I had to isolate myself in a cabin without a phone for 2 weeks to get it done – talking to the walls near the end of the second week.
I had to isolate myself, with no human contact, for two weeks so I could finish my first draft. LOL
Many revisions followed. But finishing my first draft required an Herculean effort. Once I have something written, revisions and fine tuning of manuscripts are not nearly as daunting for me.
Written and oral prelims as well as the defense were a breeze in comparison to finishing the first draft of my thesis.
Good luck with the final bits and pieces. In the end, it is worth the effort.
Whipped up a quick glassing stand there after the kids gone to bed. Used to be a canvas wardrobe, now it ain’t.
Test fit the nylon net.
And glassed:
So far that was the worst glassing experience I’ve had.
I tried mounting the net to the deck with spray adhesive. That was a waste of time. As soon as the glass over the net got saturated, the net came of the deck and stuck to the wet glass. Then it got taught and formed a fine flat bridge over the concave. Tried forcing it down, no dice.
What now? Peeled back half of the glass, forced the net to the deck, replced the glass, repeat at the other end. Worked fine, just hastle. The lam is pretty dry though. Hopefully, the hoatcoat will help. If not…moving on.
Consulted the McKee chart for the fin placement. Fronts were fine, Rears no quite, placement was right on the channel. Had to push them back about 1/4" and appart by 1". Anyway, with these types of fins, I doubt the McKee placement is relevant.
Then had to do the fin roving. Did it before, used old glass offcuts. What a pain in the ass. So went on swaylock, found a post that stated that the roving did not serve any structural purpose, believed it immediately and just blended the transition between the fins and the bottom with some epoxy/cabosil mix. I like it, its tidy. No hoovering strands of fibreglass from between your fingers.
