D5 - OneOff I

Post by ArizonaBuilder » Sun Feb 01, 2004 12:58 am

I have completed the inside seams, one half of the daggerboard box and installed the skeg.

I have placed some pictures in the gallery.

This has definitely been a learning experience as this is my first stitch and glue project...

i have finally flipped the hull and built up enough courage to attack to outer seams.

I used a resin sanding disk on my right angle grinder to round out the edges. This worked beautifully and I am totally impressed with the ease that the grinder worked with these resin disks... It was a little dusty, but that is okay..

Next i applied a stiff fillet compound using a freebee credit card to the rounded edges to smooth out any defects created by grinding.

After letting the fillet material set for a half hour. the material was fairly firm at this point.. i wet out my tape on a piece of plastic and applyed to the seams.

Those resin sanding disks also worked great knocking down the tape edges on my daggerboard box.

so tonight i am going to knock down the edges on the taped seams.

Now i am not sure what my next step will be.

i know i need to apply epoxy to the hull which has not received an initial coat yet..

Will i let that first coat harden and after that apply a second coat tommorrow, which will be my second coat and will fill the weave of the tape.

After that do i need to apply a third coat or would i move to the fairing stage with the Quick fair material..

I am running low on resin, 1 1/2 left in the bottle.. so i don't want to apply too much resin, unless i need to go out and buy some more anyways.

I feel that i need 3 coats on the hull, but if i only need two before quick fairing that would be great... i just might have enough resin left...

thanks for any input.

If you are going to go to quikfair, then I would say you do not need a third coat - it is itself epoxy so it provides the next coat for you - you just need to seal the wood so it does not suck the epoxy out of the quikfair mixture.

Sounds like you are moving very quickly, keep it up.

I applied my first coat to the outside hull this weekend and was amazed how far a little amount of epoxy would go when you used a plastic squeegee.

The bare wood looks like it will need a second coat thou, but the taped seams are mostly invisible now..

I used my angle grinder to knock down the edges before i applied the epoxy to the hull..

With using the squeegee for the first time.. i was sure i would not have any runs, but sure enough i had runs around the fiberglass tape.

It is almost like some god, holds back the expoxy from running until i leave the garage..

I guess it must be the epoxy reaction that kicks in and heats up the epoxy and allows it to flow while it sets up. And i specifically played with the stuff for an hour, looking for runs before i decided it was safe....

Right now, i don't want to expoxy anything that is not horizontal....LOL

At least the runs were not as bad as when i did the inside... there i only used a brush and did not squeegee it... so i am getting better, but not where i want to be yet.... PRATICE, PRACTICE and some more PRACTICE

I also glued up my tiller using 4 - 1/4 plywood.. I haven't removed the clamps yet.. Since i want to bond to cure before i release the pressure from the clamps, but it is looking good, so far.. can't wait to finish it bright.

I still want to place some 4 oz cloth on the outside bottom and sides to help with the checking of the fir, since i went cheap and bought AC exterior ply..

But i must say, i have been looking at all the cut edges of the pieces and have yet to find a void problem... There have been a couple of spots no more than 1/16 inch, but that is all i found. So i hope i lucked out with some half decent wood.

I know it was a gamble, but it is a small D5.

Wow, this todo list got longer and longer the more i thought about it.
even thou it looks like a boat, i have a lot of work to do yet...LOL

Well tonight i decided to fiberglass the outside hull using 4oz cloth and Jacques new epoxy. I had 3 unknowns going in, cloth from US Composites, Jacques new epoxy and never having fiberglassed anything with large sheets of cloth.

I debated a while on whether to wet down the epoxy on the hull and lay the cloth into the wet epoxy or just put down the cloth dry and spread the epoxy on top of the cloth, hoping everything would wet out fine.

so i streamed the epoxy from the cup onto the glass and used my brush to spread it around.. well to my surprise after a single stroke of the brush I had a totally wetted out glass trail behind the brush. So you can guess i did not have any issues with the wetting of the glass. It actually wetted out quicker than the 9 oz tape using system 3. But i don't know if that is a fair comparison.. 4oz cloth and 9oz tape.

I also noticed the new hardener is thinner and easier to pump than the system 3 hardner. The two resins both had about the same viscosity.

So right now i will give the new epoxy 3 stars out of 5. If only they could develop epoxy that doesn't run>>>

I guess i need to develop better skills.

If you are wondering why i glassed the outside of the hull. This is my learning boat.. I glassed the hull for experience, so a larger boat's hull would not be so intimidating, to make the hull more abrasive resistant and finally to stop the fir ply from checking.

I want to use this boat as my shore tender when i am sailing around the Fiji islands with Jacques new unseen VG27. :lol: so i need it to last a few years.

More pics coming this weekend..

Oh my.. its the return of the to do lists!

I always make mine too long for a weekend and only get one third thru them. The weather's warming up to 50 on Sunday (fahrenheit- ha, had you going Leon?). I might as well make a list tommorrow!

If the epoxy didn't run, it wouldn't wet out that cloth so nicely either. It's a world of trade-offs.

Happy D5'ing

Well my todo list is starting to get shorter, i have glassed the outside of the hull and epoxied the daggerboard, rudder and tiller.

You can see some pics in the gallery..


Daggerboard Handle with racing strips.

Image

I liked the way this turned out, I am going to take my seats and cut them in thirds and place some 3/8 ply between the cuts and glue everything back together. This should give the seats an unique look and will match the daggerboard handle. I have to figure what 1/2 wood i am going to use for the seats, i want the light look of the pine on the daggerboard to accent the racing strips.

My next task is too cleanup any runs and rough tape or cloth edges so i will be ready to fair the hull when my supplies are delivered in a weeks time.

After that it will be time to flip the hull again.. good job it is a light boat..
and add the seat cleats.. clean up tape edges, sand runs, add those fancy blocks in the rear corners of the transom and get the rubrails on.., build the seats and mast partner... STOP, I told myself, self don't create any more todo lists... look what i went and did anyways.... :lol:

vroooom vroooom .......

you can race D5's!

... against other D5's. :roll:

ps. there's nothing wrong with to do lists, as long as they are reasonable and encourage you rather than discourage. I'm learning to keep mine much shorter now. If I finish one early, checking off all four or five items, its easy enough to find something else that needs doing!

Hey! :idea:

How about an extendable Hydroplane mod for the D5, fore and aft, just enough to border the displacement / plane envelope.

No one needs to know what those extra two ropes and cleats are for. You'll beat the other D5's hands down, if you don't go tipsy and reveal your covert understructure.... :lol:

Well, it has been a while since I have updated everyone on my progress, or even worked on the boat. Other commitments and it is getting really warm here for working in an non air conditioned garage, especially while sanding. But seeing everyone finishing their boats has motivated me to get this thing done, so I can spend a little time on the water, while I build my next boat.

Here is the hull completly faired and ready for some primer.

Image

I decided to place the boat on its side to see if this would make it easier to fair the inside. You will also notice that I put bottles and foam in the rear seat. Amazing how much this stuff expands and how hard it gets. With the temperatures here it had fully expanded after a couple of minutes so it was easy to judge how much more I needed to add to fill the camber. This was the first time I have seen the D5 from a top view and I am impressed with its size and shape.. I can't wait to get it into the water.

Image

Started fairing the inside and it has been great working with the boat on its side. When I am done with the bottom half I will flip it and finish the other half. I was dreading sanding the inside with the heat now. But after connecting my shop vac to the orbital sander, I had very little dust blowing in my face. Sanding has actually been bearable when using the shop vac. I know, I should have been doing that all along..

Well, I guess my break is over now and it is time to go back to my sanding..

Image

Sanding the inside has consisted of using the RO sander for most of the areas, followed by hand sanding with a 1/2 pvc pipe wrapped in 60 grit for the fillets and 60 grit on a 8" sanding block to get those areas along the fillets where the RO missed. Reading another post, I think i might get a detail sander for my next boat. Can't wait for the fairing stage to be over. Oh ya, I am fairing every square inch to cleanup my sloppy epoxy work.
