Re: [bolger] Re: Tools required to scarf thin plywood
Hi Don & Craig -
Here comes my 2 cents worth in this easy scarfing search.
The Gougeon brothers sell (less than $25.00) a scarfing attachment for your
skill type saw that does a great job with very little practice (check out-
www.westsystem.com). However on really thin ply it may be hard if your only
doing a single layer.
I consider myself a fairly good wood worker after 5 homes and as
many boats but I've always had trouble grinding or planing scarfs by hand to
get what I would consider an attractive joint when finished. My hats off to
you if it's something you can do on a regular basis. I really think that
Paysons system is simply the very best way to go especially since it's
something your going to do on only one boat - at least for a while.
I know he explains it very well in his books, but simply all
you really need in the line of tools is a disc sander attachment for your
electric drill. Butt the 2 pcs of ply together tightly and disc sand a
slight depression down the seam. Using a roll of 4" and a roll of 6" glass
tape - epoxy a strip of 4" down the seam followed immediately by a strip of
6" right on top. Allow it to dry over nite and disc sand the glass edges to
a feather edge. Flip it all over and repeat the process on the other side
and your done and have a joint that's stronger than the wood - if it breaks
the wood comes apart not the glassed joint. It's sooo simple. I've done it
on cabin tops and severat Wharram Cats I've built.
Good Luck - Aloha - Jack Spoering

John, there is no easy way around this. Either you're going to buy
a block plane and spend the time learning how to use it, or you're
going to buy expensive power equipment to cut the scarf, but you still
need the experience of doing it by hand to do it right with a power
tool.
Buy the block plane and get a booklet that tells you how to sharpen
the edge and adjust the depth of cut. Get some scrap pieces of
plywood and clamp some scrap pieces of wood across it as angle guides.
Practice cutting the scarf on one piece. Then cut a scarf on the
other piece and see how they match up. Line them up edge to edge
and see if the two pieces are parallel or cockeyed. Use your eye.
Make the adjustment. This is woodworking; it's actually fun. There
is no instant easy solution from the home center; other than trial and
error and practice on your own time with the hand tool. Practice.
Practice.
The two edges cut across the grain of plywood are probably going to
look like raggedy crap, so plan on putting filler into your epoxy to
fill the voids and gaps.

I've tried the scarfer - pain the butt. Speaking of "the butt." Bolger
himself recommends the "Payson Joint." Just butt the two pieces of ply
together, and put two layers of glass tape on each side, with tons of
epoxy to soak through everything. I use this joint exclusively since I
learned to do it right. Lots faster, easier and just as strong as any
scarf.

Hi all -
Check out the Gougeon's West System web site. They sell an attachment
for your skillsaw that is appropriatly called "The Scarfer" that does the
trick.

Gougean(I know wrong spelling, to lazy to look up correct) Bros. make
a tool called the scarfer that goes on a skill saw, good for up to
3/8" plywood. A decent block plane is going to cost almost as much as
a router.

MDM timber's website lists two types of Brazilian Virola
plywood, the main difference being the more expensive
panels have virola cores and the cheaper stuff has a
"combi-core," whatever that means
Glue used is WBP, same as is used on Okume BS 1088, I am told.
I am going to buy a sheet and cheak it out.

With a steady hand a disc grinder can work. Epoxy is forgiving with
thickener such as wood floor, cabosil, etc. I'd also FG tape the dickens
out of it.

My two bits...
If the edge of the ply on the boat is accessible, you can use a hand saw --
I did this on the first scarf I ever cut, and was surprised how well it
worked -- you may want to clamp a thicker piece of ply to the thin stuff to
back it up while cutting. I've also used a 1 1/2 inch chisel to finish up
scarf joints. I think the low angle block plane is used as much because it
fits into one hand as for the low angle -- if you have any kind of
one-handed plane, you might try that before spending $.
On the other hand, its a good excuse reason to buy a new plane.
I think routers are overrated, it takes longer to set up a jig for accurate
cuts than it does to do the job by hand.
