Coming Soon! The ‎@WoodGrainJunkie Cantilever Trim Router Table. Official name is TBD 

Make the L bracket wider so the bolt isn't so close to the perpendicular part of the bracket. Then you can use a wrench or socket without hitting it while tightening/loosening

Cool product! Came to say almost the same thing as the first comment.... I'd actually change the nuts to through -"knobs" that you can tighten or loosen by hand. That would make installing & removing between uses much easier.

It might make the table better if it was flush to the bench top. You could use it on longer pieces of wood that way. Just a thought.

I would look into cam lever clamps. Might be suitable and give you a very rapid mount and demount option?

If this mount will be signed for other table attachments then it makes sense. If the trim router table is to be a permanent install, it’s too expensive. You could have just as easily screwed the brackets to the table.
