The foils are better. The final fairing was done with neat epoxy (tinted white.) I'll fair once more, and then apply finish coats of white epoxy.
Centerboard. The low spots are circled.
Rudder.

The storage area/office is a great place to cure epoxy. It's not attached to the main house and it stays very warm all day and night. I think these foils are almost done. I might add another coat of pigmented epoxy, but I'm starting to use epoxy like it's paint. So,,,,, it's time to go shopping for some paint.
A 75 watt bulb adds extra heat to this large cabinet.

It's tough to get good pictures of bright, white, glossy objects. These foils are done for now. I'm looking forward to sail testing them.
There's no way these foils are perfect, but their sooooo much better than the factory originals. If I decide to start rebuilding them (one more time,) I'll start with more precise templates. This one is graph paper epoxied onto 1/4" plywood.

You can see in that last shot, in the reflections on the foil, how nice it came out. Great job!

Thanks CapnK. I have to wonder how this boat will sail will nice foils. I still have to fit some "shoes" into the top and bottom of the centerboard trunk, in order to hold the leading edge and trailing edge securely in place.
Here is a look at the original shape of the board, when compared to the template (before template fairing.) There is at least a 1/4 inch gap, and in some places, more. One side was completely flat (concave in spots,) and the other side was only slightly better. Same deal with the rudder.

The boat: Waiting in the wings, as a truck project takes center stage. The air flow meter was tested with a multimeter. It has 12v in and a good ground. If the computer determines that the output voltages are not within range, it ignores the air flow meter and will control the engine with information from the throttle position sensor (not good.)

Oops, looks like a small fire in the computer. I think, this could be the problem.

Fitting the new centerboard: From the cockpit, the board won't fit into the trunk. The maximum width of the board is 1 and 1/8th", the top lip of the slot is about 1 and 1/16th". I'll feed it through the bottom for now. I'm waiting for a small epoxy patch at the forward end of the slot, to cure (just under the top work lamp.) There was a small crack.

The word from the fleet is, the board should be at 90 degrees in the full down position. This is 16 degrees of aft sweep.
A bag from Target and some bungee cords are holding the board steady.

Somehow, the foil project turned into a bottom job. I chose Rust-Oleum Topside.
The hull was fared with epoxy a couple years ago. It was faster, but there was room for improvement. I sanded the epoxy down to bare hull with 60 grit, then applied the Rust-Oleum primer. The primer went on to thick (live and learn,) 90 percent was sanded off with 120 grit paper.
The first coat of gray went down with a 4" foam roller. The paint was thinned to 7% mineral spirits. It lays down very flat; no "roll and tip," just "roll and roll."
After about 5 hours, the first coat was hard enough to sand with 320 grit (and it sands nicely.) Then the second coat was applied.
Later today, I'll sand again with 320 grit and add the third coat. The foam roller does not add a thick layer of paint, so a fourth coat might be needed. After the final application, I'll start wet sanding with 400 grit paper.

The 3rd coat provided decent final coverage, and there's a small amount of paint remaining for touch up projects.
The paint cured slowly overnight (cool temps.) Today I added a blanket and placed two 500 watt halogens under the hull. Let it warm up for a day.

I didn't realize how much square leading edge showed below the water line (not fast.) This was rounded off with a belt sander.

The centerboard was set with 3 degrees of rake. To stop the side play of the board, I have to add 1mm shims to each side of trunk slot (somehow.)

Thanks pjesus. This time of year is nice because we get a short break from the humidity.
Anyone have experience with this tape? I'm considering it to shim the centerboard in the slot but I don't know if the adhesive is waterproof. It's "Jap tape."

Marking out the bracket's territory. The other spaces need to be built up.
Way to much yard work. The old bamboo canes are removed and slowly make their way to the curb for pick up day.

The rough edges of the epoxy shoes were sanded away. They were then fixed into position. One pair at the leading edge and one pair at the trailing edge.
With the left over epoxy I did some repairs on this chair.
Could someone get J.R. on the phone please.
Re: Coronado 15 project.

The shoes are slightly wide. Rock the board forward and strike a mark, rock it back and strike another mark.
X marks the spot (where you sand.) Remove the mark then check the fit (repeat.)
And then it happened "foooonk," the board dropped into place. A good fit.

Nice trick to get those shoes done. I don't think I would have thought of doing that :)

Thanks pjesus. The boat is off the horses and back on the trailer. It's a big milestone because now, I can park my car in the garage. The area of the centerboard trunk that takes the lateral forces of the board was reinforced with epoxy and 3/8ths inch Okume plywood. I also added 4 layers of 10 ounce fiberglass along the center of the hull.

Laminated and installed a new compression post. This was a Father and Son project.
Six layers of 3/8ths inch Okume. Added stringers and new fiberglass. The dimensions of that forward bulkhead are being reduced (I'm cutting large sections out.) It was overbuilt.

The compression post install is completed. It's tied into the new stringers and the cockpit. This is now a much stiffer hull.

And the panels that were cut from the cockpit are glued back into position. This feels really good.

The rebuilt centerboard has more lift. Because the foil is thicker, the slot had to be widened with a jig saw.
From each edge I removed about the width of two saw blades. After a little finish work with a sanding block the board dropped into place.

After a few long projects the hardware is getting reinstalled.
I'm fairly sure this is West Marine's version of 4200. I hope so :) I'll confirm that with a google search now.

This is West Marine Model 14010425. Here is a description of the product copied from the West Marine web site.
"A good choice for bedding, bonding and sealing deck hardware and thru-hull fittings above and below the waterline where the need for future removal may arise."
Here is the link. A 5200 like adhesive would never be described "...where future removal may arise."

I guess that is just one more reason I try not to shop at West.
1. limited stock (who in their right mind would stock ONE hinge of a certain type?)
2. High prices
3. Untrained personnel giving out false product information

All the hardware is reinstalled. All the control lines are back in place. There have been some serious changes over the winter. Rebuilt foils, changes to the hull's super structure and a new bottom. I am very excited to get out for a test sail.
The weather in Sarasota right now is warm and overcast. The wind is light and there's a big boat show in town (the boat launch is packed.)

Here is that compression post from the front.The front triangles are notched into the stringers.The epoxy is Six10, it looks messy because it is. This is a very tight space and so perfect looking fillets are just not happening.

Replacing a signal lamp on the trailer (again.) This time I sanded and repainted the bracket and bought new stainless hardware. This stuff was a mess to disassemble so now, it's anti-seize everywhere.
Installed.
I disassembled the barney post and sanded off the old paint. It was painted a couple years ago but, it's time for an upgrade. The bolts were soaked in wd40 overnight.
