So, my quad/fish is pretty much the most active board in my quiver around these parts, aside from the LB of course. I will just cut the sh** and say it. I want to convert it to a 5 fin option, most commonly for thruster use. I love the board, I have it dialed in, I am just not a huge fan of the quad....
So, would I butcher this board, that is otherwise mint condition by trying to cut into it and install a 5th FCS plug? Or should I just bite the bullet, call the local shaper and have him do it. I just don't want to compromise the integrity of the board, since she is a cherry at this point.
Again, aside from some major repairs of the years and spending too much time in my shaper's bay in CA, I really have never shaped or done serious glassying....
Is this an ill advised idea?

Installing an FCS plug
Jul 21, 2014, 09:31 PM #2
It's possible with some basic tools but I gotta ask the question why...why not just add a nubste if you are looking for a bit more pivot...
As for DIY...I think you'd be taking a risk...I would encourage ya to try it on a broke board or a POS you have first.

You gotta get a hole saw bit first. FCS sells a 1 3/16 hole saw bit with their install kit but nobody uses it (kinda big) and you'll never find that size anyhow. Maybe get some of those FCS peel and stick template pads from Surfsource. They cost .50 cents.
Step 1: Get 1 1/8th hole saw bit and hack saw off the guide bit in the middle.
Step 2: Make a 'jig' for drilling holes in a piece of plywood or something similar.
Step 3: Drill holes. Use a chisel or flathead screw driver to pop out the foam pillar
Step 4: Put plugs on a fin.
Step 5: Pour just enough Lam resin in holes to go about half way up the plugs. Do not fill all the way or the resin will exotherm. Come back with Sanding Resin and fill all the way up when it's just past gel stage.
Step 6: You have a kid right? Do they have Playdo or some sorta clay? put a little on the leading and trailing edge of the fin to keep it in place if you don't have those FCS template/damns. Get it perfect then tape from rail, over the top of fin to the other rail. Don't stare at it and mess with it. Walk away.....walk away. This is what all shops do.
Step 7: Route those plugs flat. Sanding em sucks. You'll never get them flat if you don't have a good variable speed sander/polisher. And you'll probably start tapping weave or burning through glass around the plug if you've never used one.

2.5: Hold your plug up to your hole saw bit. Tape off the hole saw bit just a c#nt hair past the bottom of the plug. Now you know how deep to drill. Also...on a new hole saw bit you should sand around the outside of the bit so you it doesn't transfer to the glass when drilling.
3.5 : After popping out the foam/stringer pillars, you have to drill it again another 'shy' 1/8" around the bottom of the hole you just drilled. For rails you gotta go to the deck. This makes the install way stronger. For the center fin you only need to go a touch more for strength because you have a stringer for support.
If your seriously considering going for it PM me. It might sound like a lot, but it's really, really simple. Trust me.

Aren't the nubste's meant to be used as a center fin though? Even if I put those on the back side fins, it's no center pivot fin. I am not all that well versed in the quad world, but adding a center fin and taking it for a spin would answer my questions once and for all..... I just KNOW i could swing the tail around and get loose with a few more of the tricks I am accustomed to, that the current fin setup just doesn't allow.

You could also throw in a Probox box. Look into em'. You can use FCS fins with those boxes.
