Does anyone know where to get plywood panels in either 4x9 or 4x10 and what is the best way to join the plywood seams on the sides if you use 4x8 sheets to make the bigger sized side?

...it would help if we knew what part of the country you live in...for myself, the cost of off sized ply is prohibitive and some 3/4" ply, a spline and some epoxy and as smilin' Bob sez, I can make it as big as I want

I got my 5x10 plywood at a speciality plywood store. They also have 4x9 and 4x10. You might try the yellow pages for plywood stores.

As far as scarfing, etc... the best method I've seen so far is lots if biscuits in the edge... look at the photos here:

Of course I didn't use biscuits... I just butt jointed them.

I used 1/2" Laun with a 1/8" spline between the joints.



Spline router bit



On the one in the photo I had to frame out the wall to accommodate the RV style windows and doors.

But I have done the 1/8" spline on 1/2" Laun then I glued and tacked interior 1/4" Plywood Paneling to one side. Staggering the joints.

It gave me a 3/4" piece of plywood..any size I wanted with the interior finish already done.

OR..after making the 1/2" sheet the size you want cut out some of the center areas out, to reduce weight, fill them with insulation and glue and tack a piece of 1/8" paneling to both sides.

Happy Trails

Plywood specialty stores are the place to go. Be warned my 4x10 Maple cost around $125 ea in TX!

I'm with Len...that's the quickest/easiest way in my opinion. I've tried scarfing before on boats...sorry just not worth the hassle and a tear doesn't need that type of treatment on a joint. Doug

I was a total novice when I started on my tear . I layed out my 4x8 sheets so 1 seam would fall at the door to minimize the length of seam showing. I framed "Chubby" with 1/2 osb . He measures 9' 7" +/- long and 5' 6" tall. Where the seams fell I simply straddled both sheets with a 1x4 and screwed thru from outside to in , with 1 1/4 " constructions screws after adding a liberal amount of wood glue. The osb was later venered with 1/4" luan and just glued on so I was not concerened with the screw heads. When the veneer was added I reversed the pattern so the luan seams were no where near the osb seams. This greatly stiffened the walls.

Biscuits, Scarfing, Bondo, and Epoxy. Any joint close to smooth can be filled, feathered, smoothed, and covered.

I have learned that biscuit joining and TiteBond II will make the wood break other places than the joint.

Have fun. Bondo is your friend
