Plywoods

Hi. I am planning to bend the tip of my homemade skimboard by 1.5inch. and its made of 3/4inch marine plywood. Hope you guys can help me. Thank you very much.

Are you sure you want to use 3/4 inch plywood? That will make for an awfully heavy board. You might want to consider using 3/8 or 1/2 inch plywood instead. To quote the link below you add the rocker to the board by..

"The first step is to soak the board in water for one or two days in water. This softens the board up so that it is flexible. The best way to actually add the curvature is to use clamps. Lay the board on a table of some sort. Place a piece of wood (or other hard object) about 1 inches thick under the nose. Then clamp the board to the table. It would be best to use another piece of wood on top of the board to get the rocker to be even all the way across. Don’t clamp too hard cause it will crack the wood! Leave the board for 2 days or so to dry. An alternative method is to put suspend the board by putting blocks under the nose and “tail”. Then put a heavy weight in the “middle” of the board to bend it a little. The amount of rocker can be adjusted by adjusting the height of the blocks. Leave it overnight or longer. "

Check out the link yourself.. It’s a great place for all things skimming..

soak it in water and apply steady mechanical pressure?

We recently lost a rather large section of tile in our shower. My husband just put his hand on it and leaned and the edging and over a dozen tiles fell and smashed in the tub. Apparently they weren’t attached correctly when they were installed and were just waiting for someone to touch them. We took this as a wake-up call that we needed to redo the tile in the bathtub area since we can’t find tile to match ours at all.

My question is about the backing for the tile. The plywood this is attached to is marine grade plywood, and it’s coated in a thick, rough layer of adhesive. (We’ve cleared the end that deconstructed itself.) Can we level up the adhesive with a belt sander or something and then just put new tile on? Someone told us we should install a moisture barrier like some sort of sheeting over the board, but then immediately said they had no clue how well the tile would stick to one. I’ve searched for quite a while and I’m either really lousy with keywords or there’s not much on this. We’re on a very limited budget at the moment, so hiring a professional is out.

Any help would be appreciated. Thanks for reading this!

Well you can do this your self to save money. But do your self a favor and do it right. People before you didn t.
Take it all out and start at the studs.
Place a moisture barrier up first, This is just some good plastic.
Place a backer board over that. usually its just a 1/2" cement board.
Then you can tile over that with plain thinset.
As far as using the Red Guard as suggested, you don t need it at all in a tub surround shower. Maybe in a small stand up shower were the water is really concentrated. It s a great product when doing a horizontal area but not needed as much in a vertical situation such as a tub. And at 40 $ a gallon its pricey.
You can redo this yourself and have it last for years for less than 250$ if you use just a basic tile or a larger tile that has trims.
Any questions you can e mail me through my avatar and check my qualifications there.GL

I’m replacing an older wood motor mount. Can’t tell if it was marine grade or not, but it is showing some rot.

If it’s going to be used around the water you want marine grade. The adhesives used will hold up better to water intrusion.

Good luck with your repairs…

I live in Cambodia and they don’t have marine plywood but normal plywood, Polyurethane paint, epoxy resin, hardener, fiberglass mats and all sorts of latex based paints. I want to build a small Paraw, a Philippine style outrigger boat and I want to do it as cheap as possible so the local fisherman here can afford to copy it. That rules out the use of fiberglass. What other ways are there to make normal plywood seawater proof?

Coat with epoxy and keep up with repairs.
