I know these machines have their limitations and I am not trying to fix them all.
I am using it as a stepping stone until I am able to build a T Slot machine, down the road.

My Router is the X61500GT, which has supported round rails for the Y axis and unsupported round rails for the X and Z axis's.
Seeing as the Z axis rails are quite short, they should not have as big of effect on ridgity as the X axis would.....
I was thinking that could quite easily replace the unsupported round rails with supported version and keep them in the same location.
I would also fit a 12mm thick aluminim plate across the back of the gantry.
I would have to pack the rails with 3mm spacer to get them back in the same spot but that is no biggie.
I know I should use linear rails, but that would entail significantly more work to get everything to fit, and it still would not be a 'great' machine.

My though is that this would be relative easy mod that would give me the most improvement in ridgidity.....

Do you think it is worth the effort or will it be a waste of time and money?

I've seen others mount a linear rail to the back of the X axis andjoin that to the top of the Z axis to reduce defection, but I am not sure if that is a better way to go.
