So i have a dewalt dw746 it has been a great saw! Today i decided to make a zero clearance and a dado throat plate, and try out this 8” dado stack that came with the saw ( got it used). Everything went on fine, i used it with no problems, but when i went to take it off it was stuck. With some wiggling and a bit of force i was able to get them off, i then put on my thin kerf and stabilizer, went to thread the arbo nut on and it would not thread past half way…. which coincidentally was where the dado blades were getting stuck. so i unthreaded the nut and went to take the stabilizer and blade off, and they were stuck as well!!! Finally got everything off and it looks like the arbor is all chewed up. :/ I have no idea what to do now, im dead in the middle of a project with a deadline and need to use the saw. any ideas? do i need to replace the arbor, and can i even get a replacement since this saw is discontinued, im kinda freaking out a little bit over here. please help.

Thread file or small needle file with a sharp edge.

Yes the part is avasilable

Dado blades are notoriously diffucult to remove from the arbor and easy to misalign when installing. If a cutter got stuck caught on the thread and you tighten the nut in that position you got yourself a problem.
