The holes at the four corner get a 9.6mm through drill with a 11.6mm diameter 5mm deep counterbore (couldn't represent that on the SVG). You can get this counterbore roughly by doing a 2mm negative offset with an inside cut. No, I don’t make them. But for less than a tenner, I’ll tell you how to. I’ll also tell you how you should use it. I won't begrudge saving money but I do begrudge people claiming similar accuracy… If you have actually achieved similar accuracy, I could just about guarantee that if you costed time, it would have cost twice the price of the Parf... The beauty about building your own isn’t just the cost-saving or even the satisfaction of having built your own workbench. You can make choices about exactly how you want it. If you want 3/4″ imperial dog holes on 4″ centres, that’s what you drill. If you want 20mm metric dog holes on 100mm centres then that’s your choice. I laid it out pretty carefully, and drilled it on a drill press. It extends 24". After using it a few times I pretty much ignore the first row of holes now, That puts the first line into a nice spot, but if you play around with a paper template on layout you'll find what feels right for you.

I would absolutely love the process of building a “traditional” style workbench, but I also really think I would get the most benefit from some sort of MFT inspired workbench. I have come across some really interesting designs whilst looking for workbench ideas. The Heavy Duty Custom MFT I speak from experience as I have done both… made an MFT style without and with the Parf system... initially, I took care and took my time to ensure absolute accuracy with my without build… the fact that afterwards I even considered the Parf system, speaks for itself.

The Heavy Duty Custom MFT

If you don't use a 1/2" router bit, it can be a bit tedious to cut all these holes. MLCS sells a 1/2" plunge bit that has a 1/4" shank, it's called the Katana Straight Router Bit. Add about a 2mm chamfer all around the top on both sides (helps fit it into the MFT and also prevents chipping of the MDF. Cut a rectangular top at 1102x718mm 20mm, usually MDF. Be sure the top is absolutely square and the size is precise before starting. You can, of course, cut the top with the Shaper as well but it would take longer.

But is it possible to DIY your own ? Well, even if your workshop is pretty well equiped, it's not that easy, but definitely yes, you can. Any individual could make a table and fix rails, so I will not cover these subjects. I will focus on two fields that can bring success to your work :

I was considering a review and decided to do a search first and made a few hits… not being an avid reader and wade through all the responses, I hope that this response covers the subject matter with stuff that may not have been covered.
