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?
