LR32

"The stops have to be exact or your holes won't line up."

Yeah, what was I thinking. [doh]

I forgot the end of the stop has to butt to the work, so yes they
should be the same else no repeatability/consistency. I was only
thinking about the two stops being placed end to end.

I just measured mine with a digital caliper. I checked the diameter of all the pins, they are all 6.00 mm.

I then measured the pin closest to the end of the stop and they all the pins located on the same side and location matched.

I then measured the outside to outside of the four pins on side stamped 32. The dimension was 37.95 (38 - 6 would be 32 mm on the money and line up with the rail holes) for all of them except on one pair of pins on the end of one stop which measured 37.90, and that stop does not fit without being forced into the guide rail holes IF you are trying to set it so that all four pins engage a hole. The flip side or 16 only has one pin so not an issue. The other stop drops in just fine, no slop and no resistance. I have the newer style stops I guess since they are the longer, more squared off ends.

I have noticed that the stops and pins do have the slightest slop in their engagement.  A very little variance could be coming from there.  Maybe the issue is an aggregate of little variances.  Fraction of a mm from the stops, fraction from the centering of the bit, fraction from the holes in the rail (or drift pin).  For the aggregate to equal 1/2-1mm wouldn't be impossible to imagine.

Another possibility is the adjustment of the router carriage to the rail. If it is loose and you change sides the error would add and easily become ~1mm.
