Hi would reinforcing the 15mm plate with 2 lengths of 40x80 heavy duty profile
One at top of plate and one at bottom of the plate help stop the vibrations

For the gantry the easy and quick method is to use 2 pieces of 90x45 profile and fit them together to form an L section. Nothing else is required, job done.

You can bolt the gantry sides to each end of the profile . (you can tap the holes in the end of the profile to 12mm)

It's not required albert for the type of work your going to do. The L shape gantry like Clive suggested works fine with 15mm plate, it's tried and tested design which works perfectly for a wood router. I've got dozens of small business users who I've built the same machine design running them 12hr days 6 days wk making every thing from MDF letters to guitars and fine jewelry boxes with very intricate inlays etc.

Also don't stress over the bolts, just plane old nuts and bolts will work fine. You will only need stainless if you are running coolant.!
