The Bosch fixed base (MRF01) has a design flaw, I think. I wonder
about the best way to deal with it.

Not a design flaw, you are simply using a router that was intended to be
used in the traditional manner, not upside down. so you have to be
careful to not damage the router.

What you should be using is one of these.

or any of these

Or use the plunge base for that router.





With the fixed base mounted upside down under the table's top, the
router motor placed in the mount, and the clamping lever loosened, all
of the weight of the motor is supported by the retaining snap ring
(e-clip) attached to the adjustment shaft. This is a very weak
mechanism.

The retaining clip (e-clip) is held in the adjustment shaft by a
shallow groove in the shaft. When the shaft is turned to adjust bit
height, the ring can--and does--slip out of the groove so support of
the motor is lost.

Has anyone else run into this problem? Did you find a way to avoid
this weakness?
