Hi John
The holes in the chess board squares match with dowel rods in the bottom of the
chess pieces. This way a blind chess player can check out the board without
moving the chess pieces.
Plexi Glass is used here to replace pane glass. It is very strong, clearer
than glass, but will scratch. So after a few years, it can fog up with
scratches from wind.
I have some left over from another project, that is one reason why I want to
use it. Another reason that I want to use it is that wood glue will not stick
to it.
What I want to do is make a template wear I can drop in the black squares, then
add glue, and then put the white board on top of the black squares, the white
board being one piece. I would add clamping pressure and hope that the chess
board would glue up.
The reason that I am considering making the chess boards this way is that the
fellow I am making them for wants 30 chess boards at a time. So I am looking at
easy ways of making these boards.

Hi John,
I read your post on making Plexi glass Chessboards with great interest. I've
recently finished making several Chess boards myself. However, I cannot
entirely envisage your construction method.
Are the Plexi glass black & white chess squares pre-cut to size, with the
plan of fitting and gluing them 1 by 1 into a surrounding frame? I've not ever
seen or felt an adaptive chessboard, so I cannot quite picture the idea. I'm
guessing the centre hole in each square is to locate and lock each of the
chess pieces into place, so that they cannot easily be bumped out of
position? Also, the name or term "plexi glass" is not a trade name used here
in Australia so far as I know. From googling the name plexi glass, it seems to
be what would simply be called Acrylic here.
Several google searches I did on gluing plexi glass or acrylic, seemed most
often to suggest the use of 100% Silicon glue. Some also suggested that if
gluing plexi glass to plexi glass, then the use of a powerful acrylic solvent
called methylene chloride, is the way to go. Apparently, it partially dissolves
the mating surfaces, and then the two parts sort of weld together.
My own recently made wooden Chess boards were made from English White Oak and
Peruvian Walnut. to construct the Chess board pattern, I simply machined up
the 2 different coloured timbers into 2 inch wide strips. These strips were
then edge glued together, alternating the dark and light colours, to form a
long panel. When the glue had set and hardened, I cross cut the panel of glued
strips at 2 inches width into 8 strips. So, I now had, 8 strips of 2 inch by 2
inch squares, where the glued squares alternated between dark chocolate brown
and pale creamy white. Next, I took every second strip and swung it end for
end, to make the familiar Chess board or Checker board pattern. These were
then edge glued together, and set into a frame I'd previously made. The inside
of the square frame measured 16 inches by 16 inches.
My Chess boards are quite flat, and do not have the darker squares an eighth
of an inch higher than the white squares. But, I could have achieved that
differentiation by simply machining my white strips to be an eighth of an inch
thinner than the dark strips.
Hope this has been of interest and, hopefully, some help.
Cheers,

Hi WoodWorkers
I have an almost woodworking question.
I am working on making a frame or template, I am not sure which is the
correct term, for a adaptive chess board.
An adaptive chess board has the black squares about an eight inch higher
than the white squares. Each square has a hole in the middle. The current
plan is to make 30 or 40 boards at a time.
What I want to do is make a plexi glass board with the alternate squares
higher where I can put the black squares in place and put the base board on
top for gluing, hoping that the glue will not stick to the plexi glass. I need
to know what is a good glue for gluing the plexi glass squares to a plexi glass
base?
