Re: Designing a new router called Brevis-HD
Peter,
I think the rails being on top of the gantry (rather than being on the face) is a poor choice.
You have a big lever there. You normal would have the lower Z bearing level with the bottom of the gantry. With your design doing this doesn't gain much because it's still all cantilevered.
If you want the bearing bolts easily accessible, put the rails on the face of the gantry and just have the carriage/saddle wider than the Z axis.
