The 200$ boat rebuild, hopefully headed to splash town.

[Cas8101]

Hell I don't even have the plywood yet. So have no clue about the voids. I will be using Arauco 23/32.

 

[Cas8101]

I see what your saying tho WOG. If it's so rough and uneven on the C side to just float it out with some peanut butter till smooth then proceed to laminate them together

If you're using Aruaco then you WON'T have to use anything but Titebond III. That stuff is almost VOID free and really nice and flat. Buy a Gallon of glue then glue up the panels. TIP: Measure the max width and height you'll need and cut rectangles this size. Then glue up the rectangles BEFORE cutting to shape. This way you don't have to worry about the wood slipping with the clamps. Also use a small nail in the corners to hold it in place during clampling. Make sure to get ample clamping pressure on the middle portions. OR just use deck screws to "Clamp" em together. You can remove or leave the screws in after the glue cures (24 hours) One More thing. Most people use WAY to much TB III a Light even coat is all that's required. If you use more, It'll just be wasted when it squeezes out on the edges.

I used Arauco as WOG recommends, and it really is nice wood. I used deck screws (quite a few of them) to pull the pieces together and then removed them and filled the holes with thickened resin. (I didn't want to leave all those screws in there in case I ever was drilling or cutting into the transom.) Worked like a charm, and Titebond III will hold as well or better than the glue used in exterior plywood.

Arauco plywood is made from radiata pine which is not very rot resistant (google it). Douglas fir is a better choice, more rot resistant, but it will still rot.

If using Arauco, be sure to seal (fiberglass) it very well and make sure all penetrations are sealed.

I like Arauco plywood, but wouldn't use it in a boat.

Ten4 WOG. Thanks for the detailed process explanation

I understand your thoughts on it, and I agree Doug fir is a better choice than any type of pine. But what my thought process tells me, is if the wood whatever it may be is basically just the form or core of it and is properly sealed and encapsulated why the need for quote un quote marine grade Doug fir or even regular Doug fir? If whatever wood is used as long as it's done correctly bonded and fiber glassed shouldn't it hold up for many many years. Even as long as marine grade plywood, which still has to be sealed and glasses for long term life?

 

[Cas8101]

Not debating or arguing with you at all, just explaining my theory on why not Just use the arauco. I have used it for many projects in the past, it's basically clean with little to no voids and is 7 ply and rated as exterior. Maybe I'm wrong, wouldn't be the first time. And I'm open to others opinions, in fact I may even call the local lumber yard and see how much regular Doug fir ply is. But I am basically decided on not using marine grade ply. It seems overpriced for what it is and it still needs to be sealed and glassed for self preservation just like all other plywood.

 

[Cas8101]

To top it off I may have to find an alternative to arauco anyways because all suppliers in my town are currently out and not getting any in anytime soon. Nearest I have found is three hours from me and I'm bummed about it because I think for the price, there isn't anything comparable. 36 bucks a sheet for seven ply, with very few voids is a hell of a deal.

 

[JASinIL2006]

I agree with you, CAS8101, in your thinking about the wood species; the key is to encapsulate it right and to avoid treating it on such a way that it has the opportunity to rot.

Personally, I'd drive to get Arauco. Unless you go with garden-variety exterior plywood, you'll be far ahead in cost compared to buying marine plywood locally. (I drove 3 hours round trip to get mine; not as far as you need to go, but it was still a hike. I don't regret it, though.)

 

[Cas8101]

Well I'm gonna see if the stores in Houston can ship from their store to my local big box. If not I will be taking a drive, hell I will take the family and we will go watch an Astros game. Make a little trip out of it. The town I live in basically has nothing but pressure treated and yellow pine for affordable plywood and it's full of voids and rough. I can get marine, and a few options in the hardwood variety but to expensive in my mind. Douglas fir is completely non existent as an option in my town, I checked with all big box stores and called every last lumber yard here.

I'm in south Texas by the way

How would y'all attack this transom rebuild? Someone has been in this recently and replaced the top half. Top half was solid wood, everything below the deck is rot. And what would you call this transom setup? I have heard it referred to as an key lock.

 

[Cas8101]

It's kind of an odd setup I guess. But I do want to go back in with the two boxes in the back which I guess sort of act like pontoons? And I'd like to add a bench with a raised deck in front of the transom that will have some storage as well that will sit on top of the main deck.

 

[Cas8101]

Tabbed into bottom of hull and hull sides. Then build the rear boxes back in and tie and tab them into the back of the transom.

Bump

i would tear it all out and build fresh the way you want, it looks like your drawing would work out good
great part about scratch is you get to do it the way you would like it not the way that somone else did just because it was quick and easy.

 

[Sacky661530]

Okay I too just bought a $200 boat it's a 1965 alumacraft the floor is shot and it needs torn out. Do I have to put a new floor in it or is it okay to leave bare?

 

[mickyryan]

cool grats sacky make a new post and we can discuss once you post some pics
