It's easy to add nuts to the inside and underside channels of the MFT extrusions, giving clean and sturdy attachment points for accessories.  The MFT is not modified by this change.

These instructions are for the MFT1080 and MFT700.  MFT3 info coming soon.

Tools needed:
  • 6mm hex wrench (Allen key).  Needs to be large, for both access and leverage.  The wrench I used is 150mm (6 inches) long.
  • Optional:  A small impact gun with a 6mm bit would be ideal.
  • 13mm socket to remove knob.
  • Thin straight screwdriver to remove knob.
.
Parts:
  • M8 square nuts, 8x1.25 DIN 557
.
Preparation:

Procedure:
  • Remove guide rail and brackets.
  • Remove top by removing 4 screws underneath.
  • Set the MFT on its front or back.
  • Remove the two uppermost locking knobs.
  • Each corner casting is attached to an extrusion by 2 socket head cap screws.  Break the screws loose and then loosen 1 or 2 turns.  Don't need to remove them.
  • First, remove the uppermost extrusion and the two corner castings attached to it.
  • Remove one of the corners from the extrusion you just removed, insert nuts with the flat face out, and replace the corner.
  • Install the nuts in the side extrusions.  The flat face of the nuts should face the outside.
  • Remove one of the corners where it attaches to the long extrusion on the floor.  Add nuts, replace corner.
  • Reassemble MFT.

I put 2 nuts in each of the side channels, and 4 in each of the front and back ones.

You could certainly do this in a different order.  If you do, be careful when reassembling to get the corner castings in the right corners so that the legs can be reattached.  Let's just pretend I'm looking ahead and not speculate on how I might know this.

Inch fans:  You can use 5/16 square nuts in place of the M8s.  You will need to file just a bit off a side of each nut.  Tip:  Gang'em together on a bolt and do several at once.  I prefer not to complicate things by mixing measuring systems.

Ned,

I had actually posted a (not so good) photo of the channels on the MFT/3.  They actually go completely through the corner extrusions which means you do not have to take it apart to insert nuts in the channel.
 
What about cutting a small notch in the two facing upper overhanging bits of the T-track,
just wide enough to insert nuts then slide them away from the notch.

Would that impact the extrusion rigidity ?
