I bought my son new speakers for his car for Christmas. In the process of removing the rear package shelf the grating came apart
and one of the covers cracked big time. (The sun makes stuff brittle
)Of course super glue didn't stick to it and the part is obsolete
So I figured I would try to weld it. I went to Harbor Freight and with my 20% off coupon bought a soldering iron for $4 and change. I used zip ties for "welding rod". I held the cracked pieces together and "tack welded" them without filler material to hold them in place. I originally tried pieces of the grate material as filler rod but the zip tie worked better. I then welded them, I concentrated most of the heat on the zip tie until I had a small blob melted and then kind of swirled the zip tie plastic into the original plastic with the tip of the soldering iron (you have to be aware of how thick the part is if don't want the weld to come through the other side). It worked !
I cut the mesh material out of the covers that came with the speakers and fit it into the holes I trimmed where the original grate material was. They look pretty good!
