Just out of interest, has anyone tried to lay carbon over an insert? Is there an easy way to find the hole afterwards? With glass you can see it.

I resorted to using toothpicks, to stick out a little bit, but there must be another way.

dale if your coming down tomorrow or tuesday ill show you, if not what you need to do is get some carbon and chop it up then mix some resin and use a fiberglass wheel and spreed it over the insert, then get some wide green painters tape and stick it over the carbon and onto the board , then get a nail and poke the tape with it you will soon find the holes , wait for it to cure and take the tape off

Ahh, that makes sense, use a nail.

Painters tape? What is that? Is it just masking tape? Wouldn't that stick to the epoxy?

Yeah, I'll probably be there tuesday! Hopefully the wind will be too!

any size machine screw (bolt thread) that will screw in tight (like a 4mm ish) with a coating of Kiwi or Nugget shoe polish on it. Paste type old school shoe polishes are soooo damn close to normal mould releases like PLP8 wax that they are just fine. Just 1/3 the price!
Saves trying to snap / detach bits of matchstick and toothpick :)

After it sets you can just screw out the insert and countersink the hole and you're done, no drilling


EDIT: I have no idea what Keef is talking about with chopping up carbon and mixing with resin, I though we were laminating mat over the inserts...???

No worries Keef, i was just explaining how professional Board builders and repairs do it..

mark ill do a tread one day on how to use a fiberglassing wheel, here is a few pics , the first one is a finbox i made for sailing far nth qld, the problem is when you hit coral you pull the front screw through the top of the box and smash the back of the box out, so there is a sleeve in the screw holes that enables you to use smaller screw heads, the back of the box is a couple of cm longer than the chinook ,so when the back of the fin smashes the box the core is watertight

you will also notice on the back screw hole there is still a bit of green tape, the front pic is also chop carbon you will notice there is no bog

the carbon art job i cut the pads and wheeled in some chop and inserted the plugs they have never leeked and there level with the deck

you will see the wood fins, thruogh the base the foil and the front screw hole is chop carbon, i could woffle on for ever about fiberglassing wheels but gustbuster phill wants to go sailing
forgot to mention the cutouts (silica ) didnt have to remove the pads

Okay I thought a quick sketch would explain how I think it can be done without PVC sandwich around insert. I'm proposing to bevel the PVC layer on edge of insert opening so I can fold recessed layer of glass onto deck as Kimba suggested and then layer over. Any comments still appreciated.

all your missing is abit of fluff around that snags

Made a start and everything going to plan. Plugs with 2 layers of 6oz cloth fit snuggly into rebates. As some existing plugs will be near new glass or even glassed over, can I fill the holes with candle wax to eliminate resin intrusion or do I just fill with shoe polish as Mark suggested. I plan to do it in two steps 1. set plugs in & just have small glass overlap onto deck and then 2. glass over the plugs with 3 layers. Comments appreciated - especially if anyone thinks I don't have enough surface area for overlay of plugs.

are you planning on overlapping the glass onto the deck that you have used to glass the plugs

Looks good so far. What is the go with the front strap, are you using the existing outer insert?

The existing front plug is 75mm off the edge as opposed to 50mm with my iSonics as a guide so I haven't done the front two. Won't know how much this may affect stance but can always add later if problematic.

I then used the little threaded roller over some peel ply and taped it down hard.

sounds good snags, glass is hard to bend to a 90deg , now you have a wheel you can move on to the next level
in a few weeks ill be doing a thread on how to chop an old slalom down to a 40knt speed board "for the big guys"

real professional job there Brian, im going to have to give up giving advise
