DeformedTree:
I measured 30 holes by row (long edge), and 14 by column (short edge). Also measured the holes in the Perf Fence.
Standard deviation for the rows: 0.10 mm
SD for columns: 0.05 mm
SD for Perf Fence: 0.02 mm
That's using a Mitutuyo digital caliper. So it does appear the variation in hole distance in my MFT is about 5 times that of the UJK Perf Fence by my measurements.
Using my Woodpeckers 2616 square, with the two Perf Fences set at right angles to each other at one corner of the MFT, the ange between the two fences is as close to square as it's possible to see without looking through the gap.
When my MFT top is beat up enough I feel I need a new one, I wouldn't hesitate to buy one (and then check it right away); or if I need a different size top would use Peter Parfitt's jig.
