More beautiful weather.

The weather stayed nice so I did some more work. I didn't get any pictures, but I ran some finger fillets around the underside of the the deck. Now it should be well sealed against water.

Quincy painted the inside of the cabin sides, so they were ready to install.

I glued the cabin sides on.  I had dry fitted them last week, so I knew right where they fit and had already used the rasp to file the front and fit it well.

I did not cut drain holes in the cabin sides. I hope I don't regret that. I suppose I can cut them out with a fine saw sometime in the future if I feel it's needed.

Sides installed.
It looks good. The fillets looked very nice even though I hadn't practiced in awhile.

I took a few inside shots as well.
Since everything fore of B3 is already painted, I don't have to do much there. Although I will paint the exposed inside areas before I glue on the cabin top.

A shot of the nav light mount

The nav light mount looks terrible now. Some sanding will take care of it.
I will have to do some sanding of the entire deck before I can coat it. But I can do that even if it is cold.

The next step is to wire the nav light. The ends will fit through the hole and the wires running to the circuit panel will go through nylon quick release clips. That way I can replace it with another light easily without a lot of mucking about with wires.

My plan is to finish off the inside of the cabin and then get the cabin top glued down.
Then I will flip the boat and do the bottom before finishing the coamings and painting the interior.

Beautiful weather; time to work

The weather all weekend was beautiful. Near 70 degrees so I took some time to get some tasks finished up.

This will be a long post, so bear with me.

First, I hung the deck up so that I could get a the seats and do some serious sanding on them. The supporting cross bar is a trick I learned from bcbimmer on the infamous #70 thread

Hanging the deck upside down.
Then I got down and did some serious sanding on the fairing coats I had done. It really didn't take too long as the 410 compound is easily sanded.

Then when I was happy with the smoothed out fillets, I was able to coat the seats. This is a picture of the first coat on there. It really looked good.

And the fillets and fairing in the aft corners looked great. In the below picture, the colors make it look really ugly, but believe me that it is all smooth and shiny and looking good.

I coated the bottom of the deck twice. For the second coat of everything I added white pigment. That way I know I coated everything. I also know when I sand through a layer. I have a tendency to do that.
This shows the white seats and the first coat on the deck.
The next morning I was able to glue down the deck. Unfortunately, there were some drips on my nice clean seats. I need to remember to lay down plastic every time I'm doing something because drips do happen.

Anyway, the glue down went very well (other than the drips). The fir pieces fit exactly in place and added extra meat for the glue.

You can see the screws holding the deck down. I've not used a lot of screws in this build.

I drilled a hole for the nav light in the bow. It's just behind the spine, which is a bit further back than I wanted it, but it will be fine.
The mounting pad fit just right with the bevels I made. It will be angled up just a bit, but acceptable. It's hard to level something on a boat that you know isn't level on the blocks. And my garage floor certainly isn't level either.

Motor mount holes filled

These looked good. I used a trick I found on the scamp message board to poke a pin hole in the masking tape to make sure air doesn't get trapped. Good tip.
Filled holes
The top two need some filling on the inside.

Bow nav light

I bought a Perko Stealth light because it was small. The construction seems to be sturdy and it came with a rubber seal gasket.
I took a small piece of 9mm plywood and built a base for it. I sanded the base so that the bottom ply was sanded away at the center. This fits the curve pretty well.

It does have leads and 9/16" hole out the bottom. I'll have to figure out exactly where to run that through the deck.

Fairing interior surfaces

I spent some time fairing the aft corners. I'm going to have to glue the deck down soon and I'd like to coat the hidden surfaces before I do that.
Messy, messy, but it will sand nicely.

More mess in the other corner.
I also filled the holes for the motor mount. I'll redrill those to 1/4" later. I'm excited about this because I want to see that motor mount installed.

Deck doubled & flipped

Sunday I spent a lot of time on the boat. It felt like I got a lot done but I don't have much to show for it.

First, I drilled countersunk holes to hold the deck down. I worked from the front to the back and it all lined up nicely. I had to do some filing with the shinto rasp on the ends just to make sure they fit well.

After that was done, I screwed it down. Then I used 1x6 scrap VG fir that I had laying around from a house project to make doublers for the deck cleats. This took awhile to rasp them down to just the right shape. Luckly, 5 1/2" pieces are pretty close to the spacing of the gunwale & inwale near the aft. Near the fore, I had to take about 3/4" off with the table saw.

I put the pieces where I wanted them and they fit in snug, so I drove 2 drywall screws to hold them in place.

Then I flipped over the deck and laid it back on the boat. I glued up the pieces and re-sunk the screws to make sure they were aligned properly. Clamped them and let it cure for a few hours before pulling the screws before it completely set up.
Glued doublers

I also did some dry fitting of the cabin sides. It's starting to scare me that I'm near to closing up the front cabin and losing easy access to the interior.

I will need to make a decision about the nav lights soon. I can't find any nav lights that I really like, so I'm considering an LED flashlight instead. I don't plan on doing a lot of night sailing, so it might be just fine.

I plan to complete the sides and the cabin top, then flip the boat over and glass and paint the bottom before flipping it over and finishing the final bits like the cockpit coamings. It's still 3-4 weeks before I can flip her.

Nav lights followup & deck glue up

I started a thread on nav lights over on the scamp build forum.  It turns out that you need to purchase Coast Guard approved lights to avoid any problems. This appears to be a showstopper for any custom lights. I'll probably pick up a small combination light from DuckWorks for the bow.

The reason this is even on the radar is because I am preparing the deck for it's eventual glue down. Last week we had a few warm days where I was comfortable getting the deck glued together in place on the boat. It's not glued down yet, but now that it is together, I can finish drilling the holes to screw it down.

I used a 5 gallon bucket of water to hold it down in the aft and a box of old tiles in the front.

entire boat.
I can drill pilot holes all the way to the aft transom now. Once I do that, I'll tack it down in a few places and draw lines under the deck. I'll fit some blocks in there to hold the cleats and other deck paraphernalia.

Then I'll flip it over and coat the underside of the deck before I glue it down.

I'll need to run electrical wires up to the bow for the bow light. I may also wire up the under deck for LED strip lights. I think lights in the cabin may be more effective though.

CG Nav lights regulations?

According to USCG regulations, the red and green side marker lights need to visible in a 112.5 degree arc (90 degrees from the fore + 22.5 degrees abaft). The sidelights also need to be visible for only 1 mile per rule 22.
Per rule 25, I only need sidelights and a stern light, but a combination mast light is acceptable (25b).

I would like to mount waterproof LED strip lights for nav lights on the bow. The problem is the 112.5 degree arc running abaft.
The plan is to route some slots in some mating wood pieces that wrap around the bow.  I've got a crude drawing below. After a second look, I think the bow transom mounted piece would go all the way to the top of the bow curve, just for esthetics.
A way to mount LED strip lights for 112.5 degree arc.
Does anyone know if strip lights are acceptable by the USCG? Since the regs don't actually say that only single point lights are acceptable, I would think LED strip lights would be acceptable. I'm sure the visibility of the lights are good to 1 mile and probably even good to 2 miles.

Fore deck laid out

This morning I spent some more time sanding the fillets.

I also put on the fore deck lid and drilled guide holes to hold it.
the deck in place, but not screwed down.
I plan to glue the deck pieces while they are on the boat. I would like to have them screwed down while the glue sets.
I'll draw pencil lines underneath. Then flip the deck over and mount the doublers for the cleats and other hardware. Then I can coat the bottom of the deck and flip it over to glue it down.

I do have an idea for LED strip nav lights that I'd like to explore. That will need to be wired before i glue the deck lid.

Computer security guys

If there are any of you reading this, check out my other blog. I've been writing some articles on software engineering security.

Still too cold

I went out this morning to do some work. Even 1/2 hour after I had turned on the 1500watt oil heater, it was still too cold in the garage to do any real work.

I guess I'll have to spend some time with my family, playing games and enjoying the beautifully bright -- if cold -- day.

Happy new year to everyone.
