Chamfer offers almost the same visual effect.

My initial option was to suggest that, but the domestic
authorities were not keen.

I find "external" curves
fairly easy to carve using a coarse abrasive disk on a 125 mm angle

(not ideal) option would be a router.

The crosspieces are nominally 50 mm thick, so hat sounds like a
lot of chewing.
