No correction needed ,, what ya said is spot on ,,,what others have said is spot on,,, as you can see by the pictures ,,,, they just work out that way!!
If the table wasn't square ,,and you can / should check yours with a accurate square ,,,
it would make it rather difficult for the machinist to set up their jigs to cut those perfect groves with out a square edge some where .
The guy making the castings,,,,,, would be ,,,,casting blind,,, when it comes to determining the amount of materials needed to make the casting it the mold was out of square .
they know down to the ounce how much material they need .
The pictures clearly show 2 tables made years apart and they both worked out perfect and are both true to my blade .
I don't do videos,,,, and I have nothing to gain how you set up your machine .
I am just showing a way to making your set up easier , you should still check the set up no mater what way you chose to do it..
