I can hear you now, those that gasp in horror at such a notion, but believe you me it works.
This instructable demonstrates the simple construction of a scow. While all construction details are drawn from others plans and instructions the overall shape is my own making.
Most scows have straight sides, resembling a box, mine however has curved sides, making the process of building only slightly more difficult.
Step 1: Materials
On to the stuff you'll need:
Prices change every day so I'm not going to list any.
Wood, pine or cedar may be used throught except where noted. I got my lumber from Home Depot.
- sides. 2 peices as clear of knots or defects as possible. mine were 10 feet long pine 10 inches wide.
- planking. (goes on the bottom) do the math, at 10 feet long you'll have to cover a little over 120 inches for this project and it's a good idea to buy a little extra. take a calculator when you buy your lumber. 6 inches seems to be the preferred width for bottom planking but 5 or 8 inches will do just as well. They should be about 3/4 of an inch thick and at least 4 inches longer than your boat will be wide. Also with these you want them to be as free of knots as possible.
I bought some cedar fencing boards that were on sale, they were 5/8 of an inch thick and 8 inches wide and 6 feet long. so needing to cover 120 inches with 8 inch wide boards means I needed 15 boards. Because my boat is only 3 feet wide and tapers to 2 feet at the ends I had a few leftover boards.
- keelson. (this will go inside on the bottom) it needs to be longer than the sides because it will be curved. the one I bought was a pine 1x5 12 feet long
- middle seat. a pine board supported by cleats. you'll need a board 3/4 to an inch thick and around 6 inches wide or wider. Also two peices 12 to 18 inches long and about 2 inches wide for the seat to rest on.
- end seats or decks. just use leftover planking, or buy extra, to cover the topside of the ends with 2 boards each.
- ends. 2 peices of oak an inch thick and 6 inches wide will be needed. They should be as long as you want your boat to be wide, minus the thickness of both sides. You may also choose to cover these with another peice of cedar or pine.
- forming brace. (This is needed if you intend to curve the sides as I did. If you're just going to leave the sides straight you don't need this) Ideally use a peice of hardwood as wide as the sides and as long as the boat will be wide. I, however, just used some pine scraps that were long enough.
- knees. (if your boat has straight sides skip this) these are peices that will go into the corners to add strength. you'll need 4 peices of 3"x3" oak about an inch thick.
- Oars. (assuming you make your own) there are plenty of instructions on these so I won't provide one.
Tools, others help immensely but these will get the job done.
- tape measure.
- saw. a simple hand saw will work
- plane. you can usually find a little one at hardware stores fairly cheap
- 2 peices of rope. at least 6 feet long
- paint brush.
- metal putty knife or flathead screwdriver
- paint. You could go the expensive route and use marine grade and anti-fouling bottom paint. But face it, this is a cheap boat. Exterior latex house paint will do just as well. Two coats of white exteroir latex primer followed by at least one coat of your preferred color is enough. A dull grey, lead color, is suggested for the inside and a darker color of your choice for the outside.
You'll also need a small can of white oil-based paint for caulking.
- paint thinner.
- caulking. for those of us that don't live in a boatyard this is actually just cotton that will be wedged in the seams of the boat. This can be procured from marine supply stores or you could just go down to Walmart and get Peaches and Creme brand worsted weight cotton yarn in whatever color you choose (it won't matter you can't see it).
- putty. The instructions I looked at said to putty over the seams but were otherwise inspecific about what that was. I just used some wood filer from the hardware store because I didn't know better at the time. On further research I would suggest roof calking, the black tar-like stuff. you can find it in a tube or sometimes in a big gooey bucket.
- saw horses. three words people; convient working height. you can do all this on the ground but it's much easier on your back if you lift the boat up about 3 feet.
- 5d (pronounced five penny) galvanized nails. about a pound and a half should be enough. I just bought a box.
I think I covered all the basics but if I missed something it'll show up in one of the steps.
