1st timer LOTS OF QUESTIONS !

Re: 1st timer LOTS OF QUESTIONS !

Okay, here are some links in reference to the use of plywood both marine grade and pressure treated. I would spend sometime reading these links to dispell any of the myths. I consider Glen-l and georgia pacific reliable sources.

Read and decide.

Yeah I think that's a good idea.

Re: 1st timer LOTS OF QUESTIONS !

Its good to know the APA approves pressure treated plywood in boat building. This quote is from the APA publication titled "A P A The Engineered Wood Association PRESERVATIVE-TREATED PLYWOOD FOR BOAT MANUFACTURING APPLICATIONS ". The document can be found at this link: http://www.glen-l.com/wood-plywood/boatbuilding-plywood.html

For the ultimate assurance against the risk of decay, commercial pressure preservative treatments are available. Since preservative treatments render the wood an unsuitable substrate for decay fungi, treated plywood can be considered at the top level of performance with respect to longevity.....

Treating is conducted as a secondary process following the commercial treating standards written by the American Wood Preservers Association (AWPA). The most common treatment and retention level for plywood used in boat construction is CCA (Chromated Copper Arsenate) at 0.40 pcf retention. Other treatments for boat use are ACA, ACZA and ACQ. AWPA Standard C9, "Plywood - Preservative Treatment by Pressure Process", specifies that the preservative-treated panels be redried to a moisture content of 18% or less, unless waived by the specifier.

That is just too cool. And all this time people were saying that the APA says not to use pressure treated plywood in boats. But that obviously is just not true.

And it is just good common sense to be sure what ever wood is used in a boat is dried to proper moisture content before use.

Re: 1st timer LOTS OF QUESTIONS !

Question about the rack steering; Did you just add that or was it in the boat already. I ask because it seems to be really close to the hull and Teleflex says their cable should not be bent tighter than an 8" radius. If you look at the helm end of a cable, there is the large nut, and a metal collar that take up a couple of more inches before bendable cable is reached. It just looks to be a tight fit.

If you have the space needed, then no problem, but it its a tight radius, just remember that the cable will wear faster on tight bends then anywhere else. So moving the helm a few inches away from the hull might be something to check into.

Great work so far! Looking forward to seeing it together

Re: 1st timer LOTS OF QUESTIONS !

That rack steering was added by the previous owner. I dont remember if it even turned the motor. First thing I did was remove it. The cable does seem to move however.
Hey NSBCraig were you answering my question about building the transom to the top of the skin?
What's the name of the wood piece that runs under the cap that looks like a stringer? Im going to have to replace that middle one for sure, it's busted in a couple places. It was a 1x3. I'm thinking of putting at least a 2x3 for strength. Do I just glass that right to the underside of the cap? thanks again for the help All!

Re: 1st timer LOTS OF QUESTIONS !

Yeah I was talking about your transom.

I'm just gonna communicate to you through P.M.'s man or Marks just gonna keep beating your thread to death like he's done before talking circles of nonsense.

:

Lets review:

nsbcraig says:

He knows it's recommended that you don't (use treated plywood) by the plywood assoc. and still loves to give bad advice trying to prove some unfounded point.

The "plywood assoc", as nsbcraig calls it, (its really called the APA - Engineered Wood Association) says:

For BEST performance of plywood in boat manufacturing, APA recommends the use of treated plywood.....

Who is the rude idiot?

LMAO!

Re: 1st timer LOTS OF QUESTIONS !

The guy that keeps going on and on ruining someone else's thread.

No-one agrees with you that if you don't use PT everything will be ruined in three years.


Your right I shortened the name of the assoc. because it' easier.

And if you still can't read the info you really are an idiot.

Are you just a compulsive nut job or what?

Why can't you quit?

You've done this multiple times to different peoples threads and you just can't stop.

Have you seen a shrink? You may need too.

Re: 1st timer LOTS OF QUESTIONS !

i asked you to let this drop. you refused. you both have your opinion. you have both stated your opinion, now drop it. you both are making this mans post your own vendetta.

lovemylake, i apologize for iboats, you have heard both sides, it is your decision, what you use.

Re: 1st timer LOTS OF QUESTIONS !

Thanks. As I stated before since I started this project I have discovered there are a lot of opinions on ways to reach a goal. I appreciate everyone offering theirs. I'll consider all & make a decision.
I am getting ready to order some glass & resin. A local fellow that was giving advice helped compile a list. He stated epoxy should be used, but I see on the list he has 3 gallons of poly.
Any thoughts? Which should I order.

Re: 1st timer LOTS OF QUESTIONS !

Another question. Can anyone have a recomend a video I can order to help explain working with this stuff? I've read a lot but seeing it on TV seems to help make a lot more sense. Thanks

Epoxy vs poly is a long time argument. Your boat is made from poly, and lasted all these years. And at half or 1/3 the price of epoxy, it makes economic sense to use poly. But more is needed to reach strengths levels of epoxy, so you could say it results in a heaver product.

Epoxy is a superior adhesive and makes for very strong FRP (fiberglass reinforced plastic). But epoxy has drawbacks too. The two biggest drawbacks I see is that 1) Epoxy can not be gel-coated and needs to be painted to protect it from UV that caused it to deteriorate. 2) Once epoxy is used, you can not go back to poly, the reason being is that epoxy sticks to poly, but poly does not stick well to epoxy.

That is the simple overview.

Re: 1st timer LOTS OF QUESTIONS !

Thanks, I think I will go with the poly for cost reasons. The fellow that helped create my shopping list suggests:3 gallons poly, 6 10 ounce Cabosil, 1 8 ounce MEKP hardner, one 10ydx50" 3 oz mat and one 5ydx50" 10oz cloth.
My boat is 14ft. Does this sound like an accurate order?
What is Cabosil, A thickening agent?

 

[Mark42]

Re: 1st timer LOTS OF QUESTIONS !

Cabosil is a thickener. Its actually a silica. There are others available that do not make the resin harder to sand. Check out a product called EZ Thick, I used that and it works great, and a lot cheaper than Cabosil. Another popular thickener is wood flour. Any of these will make a thick paste. Just don't use micro spheres alone as a thickener, it ends up making a paste that turns runny as the resin kicks. Don't ask me how I know

That sounds like you may run short on a transom, stringer and deck job. But if you do run short, just order more.

Re: 1st timer LOTS OF QUESTIONS !

Since you are on the verge of doing the project....
Disposable gloves (buy a box ...they are cheaper that way)
Dollar store is a great souce for cheap paintbrushes that come in varios sizes..
I use empty 2 liter soda bottles to mix and use as epoxy holders. They are cheap when the only thing you surrender is the deposit
