Default plywood

I have a few other questions. I'm building a simple boat (cajun flat

bottom 10
feet) as a starter project.
The points of the bottom are plotted on a piece of plywood. What would i

use to
make a smooth curve?



A thin wood batten -- piece of pine, 1/4" thick, no knots, will work pretty
well.

Do you use a hand held jig saw to cut it out?


If you're careful. Use a wide blade. Cut a little over and then plane or
belt sand to finish.


I want to put a fancy deck on it. Would a hardwood veneer plywood be ok?

I'm
not sure if it is rated for exterior use. Other material to use?


Plywood veneers, particularly expensive woods like teak, are very thin,
leaving you no room for sanding if you don't keep the varnish in good shape.
There are various ways around this, but all of them are heavy in a ten foot
boat.

Most (maybe all) modern plywood is made with exterior glues, so I wouldn't
worry too much about this for a boat that is not going to take a lot of
abuse -- I assume that the fancy deck means you intend to take good care of
it.



1/4 inch ply is that equivalent to 6mm. Is 5.2 mm luan too thin for sides

and
deck.


1/4" is actually 6.35mm -- normally we ignore the difference, except that
most Home Depot quarter inch ply is actually six millimeter which is a
nuisance if you're using a router for dadoes. So 5.2 is actually 1.15mm
under, or about 20%. Check the drawings and make sure you aren't going both
thinner and weaker. It's probably all right, though, as plywood is pretty
strong, but it will deflect more.

Can i join plywood by a butt joint and a 1x 2 across the joint on the

interior.

Yes, if the drawings call for it. A scarf is better, but requires a couple
of practice tries to figure it out.


All my materials are to be bought from a home depot type store.


You have my sympathy. I find Home Despot very convenient, but often
frustrating.

A batten.

Buy a 3/4" x 3/4" x 1/16" x 96" extruded aluminum angle and use the back
edge.

You can pick up spots that are out by as little as 1/32" this way.

I faired out a 55 ft boat using this method.
