Wow slow down lady's no one actually said it wasn't possible to build a good router from wood.!!

I personally said wood and inparticular MDF is not a good material for a CNC machine which it isn't.. . Period.!. . . . . HASS build routers and Mills but they don't make them from MDF or Wood do they.!! . . . I never said it wasn't possible and having worked with wood all my life I know it's possible but I also know it's far from ideal and much much more work than steel.
Also carry's with it a much higher potential for failure and dissapointment even for someone compleltely used to working with wood and tooled up.

Ger is correct that most Wood based routers fail because of poor engineering or design. Often they are also compromised by the type or quality of components used and most that take the Wood route do so for budget reasons so use inferior components which just greatly compounds the issue.!
I've seen many 1000's of good builds from steel/aluminium but I've seen relatively few Good successful Wood builds.!! . . . . . For sure This doesn't mean they are not being built from wood just that they rarely last very long or are successful so don't get seen.!
