It’s overkill and very heavy but it will work.

If you just bolt the router to the bottom of the
plate the router’s depth will be limited by
3/4”, which is a lot.

Aluminum fixture plate (they are ground flat) will be lighter and easier to drill/tap.

Fashioning a router table top from steel is not an easy task. You will have a problem keeping it rust free for one thing and as Loren mentioned, it will reduce the depth of cut available. I know where you’re going with this; there are cast iron router tables available that are expensive, but if you have the skill and resources to make one out of steel; go for it!

3/4” steel plate is incredibly heavy (something like 30lbs per square foot), but if you want to take that on, more power to you. Would you be bolting the router to the bottom of the plate, or trying to machine out a space for an insert/lift?

Do you have a mill at work? Can you machine out a valley for the router base, hog off 1/2 an inch that would solve the loss of depth of cut.

Why not just go with half that…3/8” steel or even 1/4” solid plate, either one wont move for what you are going to do. Now, if as above, you have the 3/4” plate and it don’t cost nothing and the 3/4” loss of depth or height don’t matter, then yeah. Another thing to rust is not worth worrying about to me…I already have a planer, a joiner, band saw and table saw…oh yeah and a lathe that can and will rust, what’s one more?

Well….you could also mill a slot for a mitre gauge/sled. Drill and tap a hole for a “Starter Pin”. Wax the top, Rustoleum the underside….

Instead of the router hanging below the a David Marks style build, with a Horizontal Router. X /Y axis arms and clamps can be drilled and tapped into the top.
