Even these wont be good enough for what micheal needs james, they will be strong enough but not really accurate enough. These are better suited for wood routers thou do have there issues, namely crap getting on the steel surface causeing sticking etc.

Really what micheal needs is a milling machine or a very substanial frame router.? Given the small size think actually better would be a fixed gantry moving table design, could be made much stronger allowing for better accurecy. . . . thou Under stand he's trying to upgrade an existing machine so his restrained by what he's already got.

Personaly Micheal I think your on a very very fine line financialy between not being worth the trouble of upgrading and going straight into building exactly the machine best suited to your needs.
Honestly I feel that by the time you have invested money on profiled rails, upgrading cheap lead screws with dumpster nuts and stiffening the chassis and all the other stuff you'll have to invest into getting this machine something like near the accrecy you would like, which I also feel you will never achieve anyway with this type of design. Then you'll be much better advised to not waste time or money and go straight into building the new machine. . . . Also think time wise it wont take you much longer.!!. . . you'll spend so much time chasing and tweaking the old machine a new build could be done in about the same time.? . . .Obviously if the finances are available.

Sometimes it's just better to cutt your loses and start a fresh.!!
