Delta JT160 jointer table sag

[Jim Sifferle]

I received a Delta JT160 6" bench top jointer as a throw in with a lot of power tools I purchased on CL. The infeed and outfeed tables are both sagging badly on the outer edges... almost like the jointer tables were used to store heavy items for an extended period of time. I'm not expecting miracles, but I figured I'd ask ... Is there any way to fix this without replacing the tables? I'm assuming no, and the answer is probably to junk the machine. The tables aren't available as replacement parts as far as I can tell... even for the Porter Cable PC160JT equivalent.

Thanks,
Jim
