One thing I forgot to mention... Clean your surfaces before gluing with
denatured alcohol and cotton facial pads. Then apply the CA Glue and clamps.

I Would most strongly recommend you don't try Gorilla Glue or any
polyurathane! Most dissimilar plastics will chemically react with each
other. Sometimes it's heat sometimes it's just time. But either way the
seam
will eventually fail.

Corian is mostly Acrilyc so CA Glue (With strong spring clamping) actually
will weld the material together and it takes a real close inspection to
locate the hairline seam. Don't rough the surface. you want as much
contact
between the 2 materials as possible.

The best thing to note with laminated plastics is that it's all in the
chisel angle. Even with a razor-sharp skew you risk the point digging into
the seam at high speed and you'll have the famous "blow-out".

My 3 best recommendations are to change speeds, chisels and sanding
methods.... For starters, use a chisel called a "Skewchigouge" or "Skewgy"
for short. It has a perfect fingernail bevel for taking it not only from
square to round but also all the way down to your basic dimension without
grabbing the seam.

After that, I would use the Skew chisel (At a dramatically high angle) to
smooth it out. Use an extremely light touch, just enough to shave the
chatter marks and even the surface. Watch both your up and down angle as
well as the side to side angle because the back corner of the chisel is
usually the one that digs in and causes the blow-out.

Also since you're using basically a fingernail angle, use your higher
speeds
even when cutting from square to round so the chisel will cut the Corian
instead of break it off. This will lessen vibration and stress on the
joint
which is the most common reason CA glues fail.

Finally, Use WET sandpaper to reduce heat. You're getting your best
results
when you see the "slurry" instead of seeing powder on the blanks as they
turn.

I have tried sanding the faces with 80 grit to provide some tooth for
the glue, but nothing seems to help. I know Dupont makes a glue for
this product, because some of the shops laminate corian to make a
thicker front edge on counter tops.

What can I use besides tracking down Dupont's product?

Unless you are a dealer or know an unscrupulous one, you won't be
"tracking down" DuPont's Corian glue, since it is sold only to
dealers. As far as gluing it together in a lamination...good luck.
There are glues that might give you a halfway decent mechanical bond,
but you would need a thick seam, which probably wouldn't look all that
good in a pen. Epoxys are too brittle, as are CA glues. You might
give Weldbond a try and Gorilla glue might work, but it would need a
relatively thick seam. There is a product sold by a couple of dealers
that I've seen, although the name escapes me at the
moment...."(somebody's) Cement" which is supposed to be a new
wonder-adhesive, bonds under water, inside a volcano or in space...no
doubt somebody else will recall the name before I even get this
posted.

I guess you could make friends with a Corian installer and have him do
a lamination for you...it's worth a shot.
