[Shop-talk] Plastic epoxy/solvent weld

[Jim Stone]

Thanks, guys.  I think it is acrylic, too and will give it a try.  I can always try glue if solvent doesn’t work, but it is unlikely to work the other way around.  Something new for my arsenal!

The plastic didn’t break; the larger, decorative part of the clip came loose from the spring clip. It looks to me like it was originally solvent welded, not glued.
