I like the square tube idea. You can always prop them up on something if you need more depth.

Not sure about the tear out. I was getting annoying tear out with the first router bit I used. Ended up with this based on recs in some videos I watched, much better results… 1/2” shank but there is one for 1/4” as well: https://www.amazon.com/dp/B085QGLHB4/

I had to experiment a little, because I started off taking extremely shallow passes…but found I was getting a better surface when I took off a little more material (but still shallow). I was trying to barely skim the surface to see if I could avoid sanding but that was causing more tear out for some reason, so ended up finishing with the orbital once everything was level.

It's probably cheap Chinese, but holy hell this thing is good
