I’ve cut out many many chassis cutouts, but that was when I had more tools... The router I’ll be borrowing isn’t very powerful and its router table is practically a joke. But I still might be able to rig up a jig and give it a go. Afterall, it’s soft pine. Thanks for making me reconsider giving it a shot... even a less-than ideal router would probably be much better than my rickety hands and a coping saw.
