Lowe's Lumber Question

Postby rari » Fri Jul 03, 2015 8:00 pm

Hello, I'm starting my first boat build a Flying Saucer. Went to Lowe's today and bought the lumber for the Building Form, looking around and found 4x8x3/4" Oak (http://www.lowes.com/pd_59298-99899-59298_1z10t8b__?productId=3658430&pl=1). Would this sheet be okay to use for the transom, transom knee, stem and breasthook? The transom frame and boat frames I was going to try to find white oak planks from another lumber store.

Thanks!

This looks like oak facing with a cheaper core as the description says "oak veneer". From my own problems using cheap wood substitutes in a boat is a big mistake. Nobody likes to wait when your building a boat but it is the best advise I can give you. Wait until you have accumulated enough funds to purchase quality lumber and you won't be sorry sometime in the future.

The wood that Lowes and Home depot carry is not sutaible for using in boat building. It has voids in the plys and the wrong glue.
You need marine plywood.
I found that Menards carries marine plywood if you have one close.If not there google marine plywood and maybe there is a store near you

You don't want to use that plywood for the transom, or any other major parts. IF it is even exterior-grade plywood, there are likely to be voids throughout the piece.... areas between the plys that are nothing but air. This makes the wood both structurally weaker than marine-grade plywood, AND the void spaces are a possible place to trap water & begin rot. That's not what you want, considering the amount of work you're going to put into this boat.

On my very first build attempt, (a Squirt), I made the mistake of using plywood from Lowe's. In addition to the problems mentioned above, I also found, after considerable work in building the stem, that there was so much of a warp in it that the breasthook was 2" off-center when I tried to attach it.

At BEST, exterior-grade plywood from Lowe's or Home Depot might be suitable for making gussets or cheap seats.

It will pay to find a supplier of marine-grade plywood. Yes, it is more expensive. It's worth it. Here in the south, marine-grade douglas fir plywood seems to be the easiest to find. It's not real pretty, but it's comparatively cheap, and it is strong. I've used that, and Meranti, which is also comparatively inexpensive. Between the two, I definitely prefer Meranti for anything that requires bending or for bright-finishing... but I had to order it from Ohio.

Down there on the coast, I'd think you should be able to find a supplier of marine-grade plywood without too much effort.

Lowe's plywood for boats? I've made the mistake you're contemplating. It's a waste of money and time.

Plus that oak ply your looking at very likely has red oak veneers. Which isn’t an overly rot resistant wood. All other comments are largely on the money too.

Thanks for the comments! I just wasn't sure if that wood from Lowe's was good quality, I don't mind spending more if I need to. We also have some local premium lumber places, I will check if they sell marine quality wood.

Berlin G Myers in Summerville carries marine plywood. It isn't cheap and they'll deliver if you have a need for that service. I gave them the materials list for my boat and they emailed me a quote back the same afternoon.

3/4" marine grade ply cost about $70 a sheet a few years ago. One sheet is enough for a FS.

The ONLY places you should use big box store lumber is exterior grade ply for your frame gussets, and the building form. Even for the form, buy the premium stuff and use that flat concrete floor in the store to hand select the best, quarter-sawn, straight pieces you can find in the stack (nothing wet).

Good luck!

@Andy, so far I have only purchased lumber for the building form from Lowe's. So you're saying exterior grade ply will be sufficient for frame gussets? Is there a recommended thickness? I'm looking at using 1.5" thick lumber.

Also for my frames, one of the lumber places offer 6 1/4" white oak for $6 board foot. He referred this wood as 'rough lumber'. Could someone explain what that means and should I avoid it? If it mean's I can save a few bucks just having to do some extra sanding, I can deal with that.

The following are some of the prices I found today for just plywood sheets. I can only afford a sheet right now, so I can at least work on this for now and later on buy the lumber for the frames when more funds come available.

Berlin G Lumber:
Okume: $192.76
Marine Plywood (SYP?): $113.67

84 Lumber:
Can special order.

Southern Lumber:
$93.71 Douglas Fir?

A few others just didn't offer any plywood at all.

rari,

If you can only afford a single sheet of plywood at this point, I STRONGLY AND WHOLE-HEARTEDLY, WITH ALL MY SOUL recommend that you skip lumber and buy the book that was suggested in your other thread.

What you will gain in knowledge of the techniques and strategies will save you far more than it costs in time and wasted materials.

I cannot imagine building my boat without my copy. It is unthinkable. You could not possibly ask enough questions on this forum to replace what is between the pages of that book.

While you are reading, you will see the techniques demonstrated in great photos and diagrams. You will be building in your mind, and your boat will be taking shape even before the form is built.

Do yourself a favor, and place the order today.

Fair enough, you've convinced me to buy the book. This one?

The Boatbuilding with Plywood book came in today. I will be reading it as I save money for the plywood and frames. Thanks for the recommendations.

I do use the oak from the big box stores for certain parts of my build. Haven't had a problem with it yet, but then again I've yet to put my boat in the water. Anyone see a problem with that?
