Hurro...
In the planning / sketching stage for a new router, and wondering about the large torsion boxes folks build up...
Is the background to this keeping the weight down?
Without putting much through into the process I would have thought that a few bits of 19mm mdf laminated together would have similar strength/rigidity as a torsion box with substantially less effort. The down side being the weight of the beast, but you could cut 'holes' out of the middle layer bits of MDF to keep that in check a bit.
Just curious, as I'm looking at a composite MDF/Alloy build by the looks of it, and I don't have the hand-tool skill to build a large torsion box accurately and my current CNC router is no where near big enough to make the parts for one!
Cheers, Me.
