I recently replicated my MFT top using a variation of the method that Toolify demonstrated in his YouTube video. I used the Festool 20mm euro hinge bit in a Bosch 1618 router on the LR32 plate. A few comments to offer:
1) The holes were indeed a hair larger than the stock MFT holes by ~0.05 - 0.10mm.
2) In a purely qualitative fashion using "feel" only, my Parf dogs did have slightly more play when inserted into the replicated top than the original MFT top, but it was inconsequential because when I slid a square up to them, they were just as stable.
3) I did get some burning. This turned out to be largely from my shop vac that filled up and dust extraction became severely compromised. A new vac bag solved that.
4) I also got a little burning when I didn't have the plunge depth set sufficiently to plunge completely through the 18mm substrate. This left a wafer thin disk of MDF which jammed and spun with the Festool 20mm bit and caused burning when it didn't quite cut cleanly all the way through. Simply setting the plunge depth a little deeper solved that.
Given the results vs the cost, I'm very happy with the results because I only use my MFT to machine wood, and the dogs seem to be just fine for squaring and setting references. I will admit however, that I do like the "feel" of the dog fit better in the OEM top.
