Weight of sled - Affecting the initial bore of router bit?

I made my own Meticulous Z sled. It works very well.

I have not had a chance to use it much and was running the Holey Calibration today. I noticed when the router bit plunges into the panel, the sled initially rises from the surface.

I have weighed the entire sled assembly and it checks in @ 22 pounds, 8 oz.

Any suggestions on a fix? Should I add more weight? If so, how do I determine the location?

I have seen discussion in the past, but am wondering what the ideal weight is?

How do you determine the sled balance (steps)?


could the bit be dull?

or just one that isn’t suitable for plunging (not all bits are), are there
blades across the entire width of the bottom?
