Wobbly: my first 3-axis router

[Sodster68]

Well, it's never too late to change one's mind. Found a very good deal on a pair of supported rails and some ballscrews. Therefore I redesigned my X-axis with the new linear bearings and all axis with b-screws.
Y- and Z-axis retain the ground axle with closed linear bearings.
Still waiting for the major components.

I've seen rails mounted this way. Are there any problems with mounting them vertically?

If you look at the piccy here:

Thr red shaded area shows how much load in each direction supportted rail will take. In your situation I think you will be fine, the machine will probably rip through the mdf gantry a long time before you encounter a force that causes a problem with the rails.

Edit to add: You really need to rethink your spindle mount, it is far too weak. You need to make two of them that grip the spindle and put a few inches between them.

Do a google image search for: cnc spindle mount

and you will find plenty of examples to suit all budgets.

Thanks D.C.!
Yes, the spindle mount needs improving. The mount in the picture is made of aluminium but I intend to ad a support higher up. Just received my router (with mount) yesterday so I'll start design on the upper support soon.
