I cannot compare this machine to any other because I have only use two SHOP FOX mortises. About ten years ago I bought a SHOP FOX bench top mortiser and used it one time then sold it not having any more need for it and when I did I just cut them with a Forstner Bit and chisel plus I did not like the noise it, thinking I did not know the correct way to set it up even though I did a lot of research and did do it the way everyone said.
About seven years ago I bought another one and had the same noise problem and started using it less and less but now I need to knock out a lot more then I am willing to do by hand. I bought a new bit set and set it up the correct way and sill had noise but after inspecting the bit I noticed that the metal had been rubbing inside the chisel just above the top of the flute at the neck. I took out the bit and put it in my drill press to see if and how much run out there was and found there to be virtually none. I then inspected all 5 of the others I had and found the same results. I then put the drill bit in the chuck of the mortiser and found that the bit was running out 3/32” concluding that the run out seems to be the motors shaft.
So what I would like to know is do all you bench top mortiser owners have the same problem?
