1. Cockpit Floor Fastener Improvements. All original No. 10 screws and hardware still in place before starting improvements.

2. I used a 3/8" drill bit to drill through the top of the cockpit deck fiberglass down through the dark grey foam core to touch the bottom layer of the laminated deck. I then took a "Dremel" and hollowed out a greater amount of foam core below the top deck layer of fiberglass to give a greater area to fill in with epoxy.

3. Port side of cockpit, ahead of the fuel tank. The holes have now been filled with "System Three" Cold Cure epoxy. I used a syringe to fill the bottom of the hole first, and work the air to the top and out.

4. Starboard side ready to reinstall hardware.
There was some air bubbles, shrinkage or seapage of the epoxy into the foam core, so it took two applications of epoxy.

1. This "DREMEL" MULTI-MAX was very good at helping with the job. When using the 1-3/16" Flexable Scraper Blade Cat. No. MM610, it cut through old caulking like butter. I was careful and made no noticable scrapes in the gel coat. A little wipping up with a rag and some Lacquer Thinner and the gel coat was clean.

2. Showing adjustaqble RPM. at the back, and a variety of accessories for cutting and sanding in tight locations.

3. "DREMEL 4000"
I did like the power this tool had. There were times I was grateful to have bought this model.

4. "DREMEL" 5/16" CARVING AND ENGRAVING 115.

For a #8 to #12 screw, I drilled a 3/8" dia. hole with a twist drill through the gel coat and the top layer of fiberglass, down through the foam core till I touched the fiberglass on the other side of the foam core.

5. Then I went into the 3/8" hole with this bit on the end of the dremel and cut out the foam. By using the 3/8" hole in the fiberglass I could run the shank of this bit around the hole and make a bigger hole in the foam core, down to the next layer of fiberglass.
Blow the hole out and it's ready to receive epoxy.

3. Number 10 screws drilled out with 3/8" drill bit, then additional yellow closed cell foam around the inside of the 3/8" hole removed with a "Dremel". 3/8" Swim step bolt holes redrilled out to 7/16".

4. Added "Mini Fibers" to System Three Cold Cure epoxy to thicken mix for holding on a verticle surface. Filled holes with two coats of epoxy.

5. Holes ready to fill with epoxy.

6. Ready to apply hardware.
Note: 3/8" bolt holes have been drilled out to 7/16", epoxy applied to the wall of the hole and after the epoxy has set, redrill the hole back out to 3/8".

14. Can you see inside the Dremeled out hole? Past the 3/8" hole in the outside layer of fiberglass, you should be able to see how the inside of the hole is larger in order to hold more epoxy and seperate the fastener in epoxy from the core.
