Re: Mark Twain Restore!!

Ok-so I am to the point to where I really don't know which route to take:
1> I can buy 6 sheets of 5/8 BC grade Plywood (2 for transom and 4 for deck) and fiberglass it all in and spend about $700 (give or take) in the end for deck and transom.
OR
2> I can buy 4 sheets of plywood and then use pourable transom compound for the transom. The total cost for the transom would be about $450 and all I would have to do is make an inner skin for the transom since I dont have one. I would then just have the deck to fiberglass in which is where I have a question: the boat is exactly 16'6" long and 7' wide at the widest point. How much resin, CSM, and roving would I need? Drewpster told me what all he used but since he did his transom too-my supply list would would obviously be shorther so....?
This would be a more expensive route but I think it would definitely be worth it in the long run....

Any help guys would be appreciated.

boatflipper,
Glad to see that you are making some progress.
Have you decided which way you going to go yet, as for the transom?

Bahahaha that picture with the deck all rotted out and you saying you got attacked by wasps was the funniest thing I have heard all day. I could totally imagine that happening to me.

I have a 15.5 ft larson that I used seacast and coated the floor (top and bottom) very thick and used 4 gallons of resin. I asked seacast real nice and they sent me the biax for the inner skin for free.

I think I am going to go with the pourable transom, probably sea-cast. I found a 50 ft roll of fiberglass cloth that someone is going to give me so that will give me the extra money for the sea-cast.:D
I will be making a decision very soon.

Yeah those wasps were killer. They were swarmin everywhere and I was trying to stay overtop of the stringers but I danced off of them and through the floor I went:eek:

Skibum
Thank you for letting me know about the biax! Although I must ask: what is biax?:redface:
Also did you go with poly resin on the floor?

Re: Mark Twain Restore!!

Ok boys and girls-children of all ages-the boatflipper has yet another thought upon his head....:eek:
So-i figure I have spent roughly 30 or 40 hours thus far. Having said this i am wanting to begin a whole new undertaking. (in a sense) I know I had complained about the cost of sea-cast and everything but I think I have decided to suck it up and buy it for the transom. The new idea I am speaking of however included the stringers....yes most of you probably know where I am going with this....The stringers are GOOD however i was thinking-if I am going to drop as much money ino this thing as I am about to why not go ahead and do EVERYTHING right. (Yes most of you are saying I finally figured it out. haha)
Anyway-I was wondering approx how many extra gallons of sea-cast I would need to do the stringers. The twain is exactly 16.5 feet long and about 7 feet wide at widest point. I have attached some pictures for you all to help calculate the quantity I would need.
Also, could I just use a sawz-all and cut the top layer of the fiberglass off then dig the wood out, then simply pour the sea-cast in?
I know-this is epic. Just take deep breaths...:p

Re: Mark Twain Restore!!

I was lucky enough to dig the old stringers out of the fiberglass, but my stringers were totally rotted and water logged. But I still went ahead with replacing them with wood. You may be in for some digging.

boatflipper,
Just go to seacast web site and they tell you how many square inches each container will fill. To figure out how many sq inches you need it is simply length X height X width. I'm not sure how wide most folks make the stringers with the seacast but it looked like about 2".
I'm sure that the folks that used it will chime in and give you more info.
Good Luck
Bob

Re: Mark Twain Restore!!

Alrighty folks-
I have made the mental decision to get the money together and buy seacast for both the transom and stringers. This way I will never have to worry about anything but the floor rotting which will hopefully be about 25-30 years. I will then be around 45 years old. Scary thought people....scary thought...
Anyway I talked to seacast and I need 15 gallons (3- 5 gallon kits @ 190.60=546.30) They said this will do my stringers and transom! They are having a sale on 5 gallong kit with a $20 discount per kit so that saved some money along with ordering more than 2-5 gallon kits. So now I am just waiting to get the money together:rolleyes:
In the meantime I will be cutting the tops off the stringers and digging the wood out. Pics of that hopefully this weekend!
Wish Me Luck!

Re: Mark Twain Restore!!

Well I have some depressing news...this weekend i had some truck trouble and spent over $200 on it-the money I had saved up for the seacast:mad:
So I have a couple of options-wait another month or so untill i can get some more money saved up or-i can go ahead and get the plywood, resin, etc for the deck and stringers....
Any Suggestions?

Re: Mark Twain Restore!!

The idea of getting this thing done is really eating on me....thinking about just using ply and getting it done.
I came across this roll of somethin-or-other for free and was wondering if it would do me any good...I am thinking it might be csm but i really have no idea since i have never workied with it. Any help as to what it is would be appreciated.

Re: Mark Twain Restore!!

SeaCast is awesome. And the guys here using it are doing a great job. And they are even swaying me a LITTLE bit on my opinion of the stuff. BUT, as of now my opinion of it is that it's primarily for boats that are in otherwise great shape but need a new transom. In which case you dig out the rotted wood, pour in the Seacast, done. And you didn't have to rip your boat apart. For total restores like yours where you already have the whole boat torn apart, I'd just go with properly sealed plywood. Done right it will still probably outlast your interest in this particular boat and will coat way less. That's just my opinion and it's purely from a cost standpoint. Seacast is good stuff.

Re: Mark Twain Restore!!

Hey boatflipper,
Sorry to hear about the problems.
I understand you desire to use seacast. Like ezmobee stated the folks on here that have used it did a great job. With that said, The wood stringers in my boat lasted 20+ years and if they would have been sealed correctly they would probably still be in good shape. The top of the stringers didn't even have glass on them. I am going back with wood in mine but making sure they are sealed properly. With both methods you still need the glass. Seacast is several hundred dollars vs. wood $30- 60. Wood will rot that's why you need to make sure it is sealed completely. Properly done and proper storage wood should give you a lot of years of reliable service.
I'm not sure what you have in the pic. It looks really heavy whatever it is. My 1.5 oz CSM is only .020-.030 thick.
That's just my 2 cent's worth.
Bob

As always-thanks Bob:D

Anyone else have any more thoughts on what this role of somethin-or-other is?

Re: Mark Twain Restore!!

Not trying to be pushy but still wondering if there are any more thoughts on what this roll of 'fiberglass' is :D (pictures are a few posts up)
Im getting the itch to order my products and dont want to order something that I already have!
Was also doing some looking on fiberglass sites and was looking at 10 and 18 oz roving. Besides obvious thickness and strength what are the disadvantages of getting 10 over 18 oz.? Could I get by with one layer of 10 oz on my deck?
Thanks everyone for your continued support;)
