Hi,

Our daughter has this little doll wheel chair that the leg broke off
of. The leg has a wheel and it is a pretty big piece that broke off
but it fits very tightly when I put it together where it broke off and
there are actually 2 pieces that broke off and join together and I
think it would glue together nicely because the pieces are at right
angles and I would be gluing two pieces together, not one.

Depends on the type of plastic. If it is styrene based, any solvent/ketone
glue or just plain acetone will work. If it is polyethylene based, toss it
out as no glue will hold on it. You can also try heat welding it together.
Get both pieces hot enough on the mating surfaces to just start melting,
then press the two pieces together.




I was reading on this page:

http://www.technologystudent.com/equip1/glueplas1.htm

And it mentions 5 different types of glues for gluing plastic
together.


Poorly written. Unless you know the material, it is just BS. There are
thousands of plastic compounds. Some glue easily, others won't glue together
at all.

I would combine your and WW's advice.
Your plastic comment is right on plus the area being high stress could
use reinforcement.
