Those two screws are correct for that version of the 510 rip fence.Hobbyman2 wrote:the two alignment screws are shown in one of those videos,,, they are underneath the fence.
Would it make any difference though if the fence was skewed to make it parallel to the blade or at any other angle ?
There are 510 variations as well as 500 and 520 differences.
Anything other than parallel to the blade is hazardous. Usually the miter gauge slot is first aligned to the blade, and then the slot is a reference for aligning the fence.
