If the California tree huggers just knew what you were doing over there... :eek: :eek:

Looking good! You are making some good progress.

Ha Strick

You got almost 8,000 hits on this thread so far. That got to be a new Record, I don’t think it will be broken for a very long time. Matter of fact I think we should give a award for that. How about calling it the BOAT PORN HEAD PIMP OF THE YEAR award.

LMFAO :D Thanks Fellowship I'm honored. I'll get busy on my acceptance speach.

I poped the hatch out of the mold tonight. Here area few pics.

It's fits perfect and is solid. This is the way I'm going to make hatches from now on. BTW if you are wondering why I did not prime it with duratec like I did the floor it's because I was in a hurry and forgot to.

http://www.casdvm.com/photos/20sf/DSCN6282.JPG

I left it sit slightly high on purpose. Now all I have to do is grind about 1/4" off the hatch lip so it sits flush with the deck and then I'll prime it.

Re: Here We Go Again
 

Strick, its great you just did that project because I have a hatch I need to build as well. The tank coffin lid on mine was warped and cracked....basically unsalvagable, so I had the idea of making my own.

Once my Grady is back in the water I'll start work on the SC again and thats one of the first projects I plan to tackle. My plan was basically the same as yours, but I was going to put some gelcoat in the mold before hand, but since I'll be painting the boat anyway, it doesn't really matter if I do that.

Can you explain how you got those edges so perfect? I know you used clay but can you be more specific? I saw somebody use bondo to create the rounded lip....do you think thats a good idea? Did you use MDF to lay up the tank lip?
Thanks in advance...your project is looking great.

BTW Otterlycool, this is Alex from Capt. Dan's Capt license class. Remember me? I'm rebuilding a 20 SC right now. Getting the topcap off was no problem...I undid all the screws holding the cap and hull together, cut the adhesive between the hull and cap, and after some persuasion utilizing crow bars she popped right off.

http://i37.photobucket.com/albums/e5...h/IM000954.jpg

That pic is kinda unclear but shows the cap pulled foward. I later got help from a couple guys and we lifted the cap off the boat, placed it on the ground and I recored the cap and put it back on......which required crow bars and jumping on the cap!

Re: Here We Go Again
 

Strick,

why use the small plywood squares for coring? Why not just use one sheet? Will the small squares create a stiffer panel?

Re: Here We Go Again
 

Grady- I used some wax based modeling clay called Supersculpy. If you go back a page or two you will see a pic of it. I rolled it into long thin pieces and then pressed the pieces very firmly into the bottom edge around the preimeter of the mold. Then I took a plastic spoon and with very hard pressure ran the spoon several times over the clay keeping the same angle. For lay up I cut 4 small 1 inch squares of cloth and stuck a piece into each corner then I ran some 2" cloth tape around the edge of the mold. I should have taken a pic but did not.

Rich--> when I re did my hatches on my 23 they were all cored with the plywood squares and I thought that was kinda a weird way to core something. With the squares you don't have to worry about a single piece of wood being slightly warped. You get better surface contact with the squares and I do think it is stiffer because of the cabosil between the squares. Also you use less wood and you can cut up your scrap. There is only 1 layer of 1708 on the bottom of this hatch and I can jump up and down with no flex at all in the hatch.

strick

Re: Here We Go Again
 

Rich-

Most production boat builders who build boats with wood cores, use the squares instead of single sheet. As Strick alluded to, the reason is that each little square will adhere better...much more so than one large piece. Another advantage is that if you fully encapsulate each piece in resin, you are less likely to have water creep through the entire coring causing it to rot as is commonly the case with a single piece of wood coring.

Finally, the little pieces...mean less wood is thrown out as scrap....which can add up to a lot if you are building a couple of thousand boats a year.

-Ed-

Re: Here We Go Again
 

Don't forget it's easy to store squares in a cardboard box and a hell of a lot easier to move a box of squares than a 4x8 sheet of plywood. I think the resin/cabosil grid prevents delamination and increases stiffness.

Re: Here We Go Again
 

One of my first jobs in the marine industry at Sea Vee Boats Miami FL in the early 80s was reducing 4' x 8' plywood into 5" squares to feed the lamination dept. I was glad when they switched to Divinycell foam core! :D

Re: Here We Go Again
 

I have seen triads used instead of squares because they contour better on surfaces that are not flat. Works good.

Re: Here We Go Again
 

My other first job was trimming and grinding so I don't know what a "Triad" is....... :D

Re: Here We Go Again
 

No wonder you quit and went into business for yourself :D

The worst job I've ever had (not the hardest) was working on the tear off crew for a roofing company. We used to tear off all the old hot tar and gravel roofs. A six foot spade and a pair of leather gloves were the only tools we used.

Your boat is coming along nicely BTW :cool:

strick

Re: Here We Go Again
 

I know you know what a triad is, quit kidding around, for those that don't its a simple triangle. They sometime change the shape to follow a complex curve but they work great.

Re: Here We Go Again
 

More of the same stuff going on this weekend. I have to say I'm getting tired of glass work. The only consolence I give myself was that it was too windy to go fishing anyway so I may as well be working on the boat.

A marathon hatch session:

A couple pics showing the molds for the 5 hatches that were left to be fabricated. The two bigger ones will go on the casting deck while the three smaller ones are for the transom cap.

http://www.casdvm.com/photos/20sf/DSCN6285.JPG
http://www.casdvm.com/photos/20sf/DSCN6286.JPG

Pre cutting the coring to fit. The three smaller ones are non weight bearing so they will not get any coring.

http://www.casdvm.com/photos/20sf/DSCN6289.JPG

This is the modeling compound that I've been using for the radius's.

http://www.casdvm.com/photos/20sf/DSCN6290.JPG

It has a waxy composition so it smooths out really well and you can prime or just glass over it without it being effected by the resin. I just push it into the corners.

http://www.casdvm.com/photos/20sf/DSCN6291.JPG

and smooth it out with a spoon and my fingers

http://www.casdvm.com/photos/20sf/DSCN6293.JPG

a shot showing the finished edge

http://www.casdvm.com/photos/20sf/DSCN6294.JPG

Once ready the molds were waxed and duratec primer is applied.

http://www.casdvm.com/photos/20sf/DSCN6295.JPG

While the primer is still a little tacky I start the lay up. I like to take some cloth tape and cut some little squares to put into the corners of the mold. Then tape the rest of the way around.

http://www.casdvm.com/photos/20sf/DSCN6299.JPG
http://www.casdvm.com/photos/20sf/DSCN6298.JPG

Once the edge's and corners are wet out then I start putting down the matt. The mold gets 2-3 layers of matt. Strips of matt are also applied around the mold edges and corners.

http://www.casdvm.com/photos/20sf/DSCN6300.JPG

Over the matt goes 2 layers of 1708. I let this all set up and then apply the coring.

http://www.casdvm.com/photos/20sf/DSCN6301.JPG

The hatches pop out of the mold easily. The modeling compound can be reused.

I've shown these areas before were I faired the area under the gunnel cap were my panels came to an abrupt end.

http://www.casdvm.com/photos/20sf/DSCN6144.JPG

Today I glassed over the fairing compound to prevent any cracking. It was a royal PIA. I had to mask the entire boat and then laying on my side I put a layer of matt over the
filler.

http://www.casdvm.com/photos/20sf/DSCN6315.JPG http://www.casdvm.com/photos/20sf/DSCN6318.JPG


I'll feel better now knowing that there is glass over these areas.

The transom has been faired and sanded over and over again. Today I put a thin coat of primer over it so blemishes will stand out better. It's getting there but there are still a
few small spots that need attention. Fairing a transom is a lot like taking a trip into Never Never Land.

Re: Here We Go Again
 

Nice documentation of the whole process, I'm ichin to try that clay and mold technique.
Being an owner of a 20SF I'm liking the way the casting deck is looking. Being able to stand up next the the edge without stepping on the rod boxes is a nice feture. Nice Job!!

Re: Here We Go Again
 

Looks great Strick. You are becoming a human hatch making machine. I made a hatch for the big Mako a few weeks back, its not easy work. You just knocked off a whole production of them! Strong.

The boat is coming together rapidly! Keep the steaming ahead in FULL. Once I finish my Mako 21, I have vowed to not take on another major refit project. I've had enough... of listening to crap from my wife about my stupid boats.

Re: Here We Go Again
 

Don't give in, thats what they want. :D :D

Re: Here We Go Again
 

Strick....is that Duratec primer that you're using in the mold???

Re: Here We Go Again
 

Ringleader you ought to finish a boat first! until then quit yer bitchin [img]/forum/images/graemlins/tongue.gif[/img]

Strick- looking very very nice, those hatches are better than some I have seen on new boats.

Re: Here We Go Again
 

I am nearing completion on one right now. 1 more weekend of glass work and its off to a paint shop. Then a month of rigging and she'll be functional.

Re: Here We Go Again
 

Poor Ringleader . . . he probably hears that from his wife everyday. :)

Re: Here We Go Again
 

All Ringleader has to say is “Honey I decided to name the boat after you”.

the weather on the bay was beautiful last weekend , unfortunately the fishing sucked. i should have worked on my boat

Re: Here We Go Again
 

No. I hear much worse. The way she degrades me and my boat projects... Shameful. She hates boats and those who own them because they take men away from family time. What a crock.

I tried that. Actually was going to name the big Mako after my daughter. It didn't make things any better. Bummer.

Re: Here We Go Again
 

" Take away from family time" is a crock your right!! I was out on the boat after a couple weeks of being born!! Me and my father so i'm told went out every weekend on the ole' skiff pulling traps and fishing while ole' mom cleaned cottages!!! LOLOL :D We probally waved going by the cottages!! lol :D See the whole family was there!! :D

Re: Here We Go Again
 

I would have to agree. If it wasn't for boats and my father, our family would probably be spread out across the country or disfunctional or something.

Good luck Ringleader! I have two daughter 2 and 5 and I get them out on the water as much as I can. Bring them to an Island, let them play in the mud, play with slimy fish, etc. Hopefully you can do the same so she can grow up with those experinces. I will do all I can to fight the "princess" syndrome.

Didn't mean to derail the thread, lets go back to Stricks' project. NICE JOB Strick!!! :D :D

Re: Here We Go Again
 

Hang in there Ed. Once you get the big one running you can get the family out in it and everyone will have fun. My kids love going out with me. I let them drive the boat and they get a kick out of that. I'll jump wakes with them in the 23 and they laugh like heck.

I named my ArenaCraft after my daughter but I was already divorced so it really did not matter what I did :D

I started that project while I was going thru the divorce. It really helped me keep my mind occupied during those tough times.

The first pic is the only one I have of the construction. This was back in my glass over wood days.
