8x4 router project

[John McNamara]

Hi Cynic

The link below points to a build I worked on with a mate a while back 2013. The machine is still being used almost daily by the men's shed where it is set up. the X and Y axis uses timing belts. the only changes made have been two Makita routers, and now it is on its second 2..2KW Asian spindle. Yes it is used a lot.

If the timing pulleys and belts fitted to your robot bits are in good condition I would give them a try.
It is worth remembering that the total accuracy of a machine is the sum of all the parts and how they are aligned. Timing belts do work as this machine has proved.

Regards
John

Cynic-al,
If you've been reading this forum for a while you will know the sort of precision that John McNamara works to and so an endorsement of using belts from him is worth having.

John,
I notice your machine uses fully supported rails (as does mine) rather than Hi-Win or similar. With the high usage you say the machine gets have you had many problems with wear and play in the linear bearings?
