About this deal

My jig is going to be made from an offcut of 18mm MDF, the stuff I'm using is veneered, but I'm just using that because it's what I had to hand. If you’re not familiar with the LR 32 system – what it does, is allow you to (in conjunction with a Festool router, drill precise holes at multiples of 32mm).

But, because my start corner is set in by 100mm from each edge, I'm also going to add another 100mm to each of those figures giving me 700, 900 and 1100. This could be the reason the guide rail brackets and fence attach and reference from the extruded side rails and not the holes in the top. A little tedious maybe but not as bad as I imagined and - as MikeK said - the accuracy is very impressive.And then I added a round over to the top edges of the trim, this is going to make the edges more durable. With the top cut to size, I brushed away any dust and then started to apply some finish, it seemed like a good idea to get it on before drilling the holes.

Sometimes factory cut edges are not as square as they should be so it's always worth checking for projects when accuracy is important. I guess that can also be said for various jigs and aids, but those were created for a purpose that the Festool MFT's were not. Used to hold standard prepared timber on its edge, these platform saddles make for a fast and flexible method of creating a sacrificial work standoff. Turning off the personalised advertising setting won’t stop you from seeing Etsy ads, but it may make the ads you see less relevant or more repetitive. I'm using some water based varnish which is pretty much my go to finish when I want something hardwearing, it's great stuff.If you are interested in a work surface with lots of 20mm holes for clamping and are not concerned about the accuracy, the MFT/3 top might be ideal.

So remove the dogs and reinsert the dogs 100 times into that CNC machined MFT you had made and the apply pressure from different directions to the dog holes and then simply measure the pattern and you will find out that your perfect MFT is less than perfect. As flat overall as the very best plywood with a surface smoothness nearly equal to MDF but much more durable and moisture resistant. I chose moisture resistant just in case I ever spill any liquids on the table top, as I wouldn't want the wood to swell if it gets wet. After a few different tops, I had nicked a couple of the holes in the template top and I had to deal with that during the last build.Woodpeckers took 2 new Festool MFTs and an old Festool MFT and measured all three of them on their vision system. I'm not aware of anyone else doing the 'sacrificial strip', but please use it - it works really well! I just secure it with dogs and a clamp, drill out most of each hole with a 1/2" bit, and then finish them off with a 1/2" pattern bit. In this video I make a MFT top for my new workbench / assembly table for use with bench dogs, fences and accessories without the use of a CNC or any expensive guide jig systems.

Then for me I do not find just having the 20mm holes makes for a complete setup for me so I also route in the dovetail slots for using microjig clamps and fitings which transforms the whole experience. I'm thinking of making a laundry tower for our basement and figured that MDO was a decent starting point for that environment, all things considered (basement, laundry, sink).The dimensions are perfectly matched to the MFT top and it has these 5mm holes on this side that are parallel to this edge. The 20 mm hole grid system has become established in our (metric) countries and can be combined with a wide range of accessories for multifunctional tables.
