This thread encouraged me to try for myself.

You can add the cylinder in two pieces from the outside, each of them going to first face.
Not with a fillet in place, because then it goes from this:
(Resulting cylinder goes on for more than 9 metres in the Y-direction!)
You can't do the fillet after
adding the cylinder either, because FreeCAD refuses to do it.
My provisional solution is to pad the cylinder to a fixed dimension (in this case 40mm conform the drawing). And then hollow the body out by making a boolean cut with a different (smaller) body I made for the purpose.
Still can't make all the necessary fillets though. I understand that people are working on the fillet problem in FreeCAD, I fervently hope they will succeed in fixing it.
