I bought this a while back to check the alignment of of my MFT and up until last week, never inserted the bench dogs to lock it into place on my MFT. Guess what, I can't get two Dogs in thru the Square and into the MFT. Something is mis-aligned. I have a chamfer tool so I put chamfers on the dog holes but it did not help. This is an original top/MFT and never had an alignment problem with anything on the top. Anybody else have issues with it???
