IMO, a better alternative to the Felder parallel fence would be one with a DRO rather than an Incra unit. ?The challenge with a lot of these is getting the parallel fence stop to be identically positioned to the stop on the crosscut fence so both ends of the cut are precisely the same width. ?An Incra parallel fence isn’t going to help with that IMO. ?

I find setting the stop position precisely on the Felder unit challenging because the calibration lens is so far from the markings on the tape. It leads to lots of parallax error. ?Brian Lamb makes a very nice alternative with much improved readability of the measuring scale. ?He also makes a version with digital readout. ?

I am very fussy about getting the crosscut and parallel fence stops identically positioned. ?Nothing bothers me more that to be assembling a cabinet only to find the front and back of two adjoining panels are 1mm different in width. ?I came up with my own contraption to get the parallel fence stop to agree with the crosscut stop position exactly. ? You can see that here along with the Felder and other parallel fence alternatives including the versions from Brian: ?
