He-he. Ordered a table insert for the Bosch. That way, when I sell it by the time I use my Harvey, the Bosch will be fully operational when I sell it.

Or I can keep the Bosch as my rabbet/dado machine.

That can be sharpened for multiple use right?! how thick is it?

My 2012nb has been with me since 2013 iirc. never had issues other than dull blades.

I think you never had issues because you have never run boards with nails through yours. I work with reclaimed lumber and even with careful inspection i have accidentally planed nail heads through mine =/. I truly wonder if that is the real cause of the warped set plate+broken thin blade... the wedged chips underneath are just the aftermath...

That or Ding and I have never cleaned the mating surface and torqued the bolts tight enough. I'm scared of stripping the threads on the bolts din kase.

I have not measured but the 5k resharpenable blade for the 2012nb does look a bit thicker as far as i can tell from the packaging...

My theory is, the still partially attached splinters in your reclaimed lumber (result of pulling out nails) got wedged under the plate. This raised the plate a bit, creating an opening for more debris to get into.

My theory, too, Joey.

Changed out a bunch of things in my 2012NB: sprockets, set plate, blades, belt.

Runs ok now but there is a ticking sound. That happened before when the torsion spring came loose. I checked and the trosion spring is still in its place but the chain catches intermittently. The machine planes fine but I know now that when there is an unusual sound, I should attend to it. Torsion spring and chain are cheap so I ordered them.

BTW, the last order i posted, Mayon game me a discount: Just P7k for the whole lot.

I think Gattaca is correct that the blade holder hit something hard enough to bend like a left over nail. I run hardwoods like Kamagong and Kaimito (yung galing kay JT) to a point where the noise is just too much. I don't think splinters can do that no matter how hard the wood. Other than a nail hitting it, the only thing I can think of is that the holders were not properly tightened in sequence. This should be done from the center outward to ensure that the blade is properly held down.

You could be right about the nails, Sonny. Am aware that the blade got chipped once which is why I now use a magnet to detect embedded nails on reclaimed lumber.

As for proper tightening, was sure I followed the right sequence last time I flipped the blades.
