One Sheet Plywood Boat – GardenFork

One Sheet Plywood Boat – GardenFork

– Today on GardenFork, learn how to make a simple boat out of plywood. You’re gonna love this. Hey everyone, I’m Eric
Rochow from GardenFork, G-Fork for short. We were watching Make Magazine,
one of their video podcasts, and it had Deek from Tiny
Yellow House on there, and he made a boat out
of one sheet of plywood, and I said, “I wanna make that.” So, this is kind of an homage to Deek. We’re gonna make a boat
outta one sheet of plywood. It’s his design, I’m gonna
make some modifications to it, kinda put the
GardenFork spin on it, but I watched his video about 10 times, I think it’s pretty cool,
so I’m gonna show you how to make this really cool boat. First thing you gotta do is
you need a sheet of plywood. This is some 3/8ths
roofing sheathing I got. If you want this to be a
smoother surface on your boat, you can get some smoother finish plywood. I think it’s called finish plywood. But this was like 12,
15 bucks at the store. Buy two of them, in
case you make a mistake. The easiest way to do this, as Deek says, is to go to the lumber yard
or your home improvement store and have them cut this wood. You want it into two one-foot sections, and a two-foot section. I didn’t have them cut it, so I’m gonna show you how to cut it here. The best thing to have for this is this thing called a chalk line. I don’t know if you ever
used one of these before, but it has chalk powder
in here, and string, and I’ll show you how this works, okay? I’ve marked out here our
two one-foot marks here, so what you do is you first shake that up, make sure that the chalk
is coating the string, and I put this right there
on the one-foot mark, and then I line it up here, and then it makes a line. – [Woman] Cool. And action! Woo!
– Nice, huh? – [Woman] Nice! Waitin’ for the boat ride. – Off of your two-foot piece, you want to measure 17 inches. All right, so what we’ve done here, I’ve taken a piece of
string, I’ve taken our bow, and I set it at a 45 degree angle. I have an angle thing, I put
that underneath, set it to 45, then I take one of the side pieces here, and I’ve lined it up so
it’s flush with the back, and then underneath I take a pencil here, and I’ve traced my cut line here. ‘Cause this is gonna be
the front of the boat, and this is where the side
of the boat’s gonna meet it. I’m gonna take some small finish nails, and I’m gonna start them at the very edge of the bottom of the boat. We’re gonna be using silicone
caulk, and that stuff– – Nasty!
– Doesn’t get off your hands. Make sure it says silicone on it. – [Woman] Why, what are the other options? – Other kind of caulk like painter’s caulk or stuff like that. So, silicone is waterproof,
see it says there, waterproof. – [Woman] Oh. – This is for bathtubs, stuff like that. – [Woman] So you have to use the silicone. – ‘Cause this is going in the water. – Seaworthy.
– Yeah, so it doesn’t leak. This is the leak-proofing. – [Woman] Excellent. – So we’re gonna take this. – [Woman] Yeah. – And line it up on there. – [Woman] Oh, it’s a little wobbly. – Okay, do the same
thing for the other side. Okay, the front, plenty of caulk. – [Woman] Should there be a space here? – Yeah, there’s gonna be a gap and we’re gonna caulk
the heck outta that gap, with the silicone caulk. – [Woman] Oh, that’ll keep us afloat. – Yeah, hopefully. Push it into the joint. – [Woman] Does it need a couple coats? – Yeah, we’ll do a couple coats on this. When I said one sheet of plywood, it was one sheet and a little bit. You can make this outta
one sheet of plywood, but you can actually make the boat a little bit longer so it’ll fit two kids, or two people a little better, if you use the sheet of plywood
plus one piece of scrap. This is a two-foot by one-foot piece. You can go, if you go to
your home improvement store, in addition to four by
eight sheets of plywood, they sell two-foot square
sheets of plywood as well. You can buy one of those,
plus a four by eight sheet, and you’ll have a bigger boat. You can do it with one
sheet of four by eight, but if you want your boat a little longer, get a piece of scrap. Maybe this is in a dumpster nearby, maybe one of your neighbors has one. Just go ask. Okay, we’re done. – [Woman] (laughs) We’re not done. – Alright, so here’s my idea
of changing it up a little bit. This is called a batten or one-by-two, but we use them for garden sticks. They’re usually, you know, this tall, and then we cut ’em a little shorter for trellises and stuff. You can see our how to make
your trellis video on our site. But what I want to do now is
measure all these lengths, and we’re gonna place
this in here like this, and we’re gonna screw it from the side and screw it from the bottom. We’ll first lay in more
caulk, and then screw this in, and that’ll make it pretty strong. I’m using 3/4 inch wood screws. Phase one is complete. I gotta put one more piece in here. – [Woman] A reinforcement piece? – Yeah, I forgot that one. How unusual. – Almost complete!
– It’s looking really good. Take some scrap wood and make a keel. Put a little angle at the front. We’re gonna put it right
down the middle here. Waterproof wood glue. I took a one by two, cut
the angle at the front, and made it run the length of the boat. Okay, always have your
personal flotation device. – [Man] Do you believe
you’re about to sink? (woman laughing) – So, a couple things I want to point out. I put these one by twos on the side here, and then I put one across the top. We gave it a name, painted it red. I think we’re ready to go. You wanna watch? – [Woman] (laughs) Yep! – This is gonna be fun. (laughs) It floats! – [Woman] It’s a little
lop-sided. (laughs) Yeah! Wow, it is good. You see anything floating? You see any sharks under there? Snappers? – No, but I see some
water coming through it. (laughing) Alright, very cool, you can do this. We’re gonna build more plywood boats. You can find out more about this, I took a bunch of pictures
of us putting this together, at our site, GardenFork.TV, okay? Use this information at your own risk, but this is really cool. I think this’ll be a fun
project with your kids. You gotta let the silicone caulk dry. We kinda rushed it a little bit, so we’re getting a little
bit of water on board, but this is great. I wanna thank Deek and Make Magazine for inspiring me for this. There’s also another site
that has similar versions of this book which I’ll put right here, ’cause I can’t remember the name of it. But bunch of plywood boat plans there. – [Woman] Bring your friends. (light upbeat music)

  1. Try the loctite polyurethane sealant for roof and chimneys very waterproof and cures fast. Sealed a huge crack in my kayak. Get it at lowes in a 10oz tube for $7. I never have had luck with silicone or caulk. I even did my gutters with the poly stuff

  2. Hello!May i say that you ve done a wonderful job!And entirely inspiring and encouraging! How beautiful! Beautiful Beautiful Wonderful! im very experienced ,but still not at all either perfect,by any means,nor knowledgeable either even,as id like and wish-even need to be… but i do what i can on a very limited budget…and enjoy learning.For many,many years indeed boats,especially small water crafts-canoes,kayaks and jon boats…like youve beautifully demonstrated here…are an especial love and enjoyment…fascination,allure,and fulfillment!-and hobby! … but just look what youve done here! Absolutely WONDERFUL BEAUTIFUL INSPIRING FULFILLING to see -and more! Perfect job! And look at alll the helpful and useful imput and tips others contribute and offer here!

Treat them as special-as they are-daily & nightly! They are precious blessings and gifts! All the best of the best!

  3. Yo GardenFork, next time you do a wooden boat project, and you need to seal the seams, use a calk called LIFE-SEAL. It's made by a company called Boat Life. I used to build fiberglass boats and that's the sealant we used. The stuff keeps the water out, but also, its one of the strongest adhesives there is. Seriously. We used to glue transponders onto the bottom of our boats using just that stuff and I had to change one out. A guy from the layup shop had to come by after I was done and repair the hull because the calk RIPPED PART OF THE FIBERGLASS OFF. It's that strong. Not inexpensive, but when you're in the middle of the lake, or out in the bay, you'll be glad to know its working in your best interest. ๐Ÿ˜‰ Here's Boatlife's page on Life Seal –

  4. I built one out of particleboard. The cheap stuff and believe it or not it lasted all season in ny summer I painted it with rustoleum red deck seal paint LOL

  5. My Dad built a 30" Herreshoff Catch Sail Boat in our front yard….Solid Mahogany slept 6 and sailed all over the New England ports…..So I know a little about this stuff…your project made me Chuckle, thanks…Btw it took 16 years because he refused most help….Launched in 1980 and still afloat…(new owner).

  6. can this carry me weighing about 27 KG? And please tell me where to get bouyant plywood in indian market (as i am hindu). Or tell me if i can get giant pieces of plywood in indian market.( yes i am about 8 years old.)

  7. you should probably check if the wood is treated i know what im saying
    my dad is a carpenter. also the water proof glue is expensive 45$ a bottle and he used like 2 of to dry the glue it takes 24-26 hours

  8. Screws and Glues! The most Awesome and strong combination. You are very smart engineer.
    Thanks for showing this. Love it.

  9. Nice! I was thinking of making Two of these and hooking them together. Kind of like an out-rigger. And then you can have two people. Also I was thinking of making one just slightly smaller so it will fit inside the other one for transport in the back of my truck. Have some easy clamp system (or something) to hook them together in the water. Yes… going to try this. haha

  10. To paint it use an oil based enamel. High gloss. Wooden boats rot. Eventually. This will make it last… If you take it out of the water and let it dry out when you're not using it it should last 20+ years. Fiber classing lasts long but needs to be out of the sun when not in use…

  11. When I was about 12, (56 years ago) I designed and made a boat using this method. I sold my bicycle (without telling my folks) to get enough money to buy the plywood. I bought 3/8" ply which was not ideal for strength but it meant that it was light enough for me to carry the boat, (on my back, like the shell of a tortoise) to the canal near our house. I strengthened the joins with batons as you have. I made a paddle from scrap ply. I did use the boat at least once but I have no memory of what happened to it after that. I bet my folks took it away to save me from drowning! This video really reminded me of my own project, thanks!

  12. I did almost exactly this when I was less than 10 years old and I got out in the middle of the river and thought I was going to capsize it and drown (couldn't swim). This is not what I would recommend. Why not build a half decent boat that performs better?

  13. Seems like an easy build. A beefed up variation could be making it twice as long and a foot deeper then put a small cabin in the back. Then double rear transom plywood to hold a small 2 to 4hp outboard or electric motor.

  14. I wish I could make one but they would allow me to have tools in prison saying something about breaking out or dillinger someone they love us so much they looking out for our safety so much that they put us in these rooms with bars so no one can hurt u they even take turns washing us in the showers and if we drop our soap they get behind us so we don't fall or have prostate cancer cool of them to look after us then after that they follow you around and take care of you letting you share a room with you and make sure no one else help you

  15. "You need a bigger boat …" Doeng doeng doeng — sorry, I could not hold the Jaws-reference. Good design, good build, good video.

  16. Paint it with liquid rubber roofing compound. Or if you want to go for it, roofing bitumen, and boil it into the wood with a propane roofing torch.

  17. Bravo bravo bravo ๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘๐Ÿ‘โœŒโœŒโœŒโœŒ๐Ÿ˜š๐Ÿ˜˜๐Ÿ˜™

  18. Wow, I remember this vedio was posted before 2014 because in 2014 I built a boat based on this video wow

  19. Quando eu tinha de 9 a 10 anos de idade fiz um barco parecido com este , palavra! Passeava no brejo perto de casa .Um dia algum invejoso que se dizia amigo jogou paralelepรญpedo dentro do mesmo e arregaรงou todo o fundo fiquei muito chateado!!!!

  20. I made a version of this Boat which is bigger(2 sheets) and at first i added a v bottom because it was made for the ocean waves but they didnt last and made me casize 5 times in 10 minutes and now i cut off the v bottom and it works THANKS GARDENFORK

  21. Iโ€™ve got a great idea….letโ€™s cut a hole in the bottom of the boat floor and see what happens….because what could possibly go wrong???

    Rumour is theyโ€™re going to rename it the USS Coffin

  22. Not a bad little boat! I might just have to make one for myself! Just let the Silicone dry, and you should be alright. If it were me, I'd add a small motor, & I'd also add some type of flotation devices, one to each side of the boat, kind of like some Islanders do to their boats. It definitely helps with stability of the boat, and makes it basically impossible for the boat to either sink or capsize, or, if you will, flip over. Those types of boats are some of the safest boats in the world!

  23. Great job.๐Ÿ˜„๐Ÿ˜„๐Ÿ˜„๐Ÿ˜„๐ŸŒท๐ŸŒท๐ŸŒทโค๏ธ๐Ÿ‘Œ๐Ÿ‘Œ๐Ÿ‘Œ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ๐Ÿ‘๐Ÿผ
