In my previous post where I suggested you might jig up and use a belt sander I was trying to gently hint that using a router, inverted or hand held, was probably not a good idea.
I'll update my recommendation to say explicitly that trying to pattern cut those tiddly little bits of wood on a router table is a technique highly likely to lead to injury. My recommendation is, don't even think about it (not even with your new and yet to be delivered router bit) and find a safer way. I've suggested one, Adam has suggested another, and there may have been one or two alternative safer suggestions made that I don't recall without scrolling back through all the answers.
So, in case you missed what I said earlier: just don't do it. Slainte.
In my previous post I answered on the merit of possibility (i.e. you said that the top bearing would’ve prevented the cut, which is not necessarily true), not on the merit of safety.
However, I take your (and other people’s) advice of experienced woodworker very seriously, and that’s why I’ll make a jig for the belt sander to finish this little piece
