I just finished gluing together a model 80 with a similar problem of water damage at the bottom. It seems that the front panel was originally fastened to the arch by glue in the groove, along with the two glue blocks near the bottom, so that's the way I redid it. Without gluing the groove, the cabinet would be very weak and flexible. Its a pretty flimsy structure overall and needs all the strength you can give it.
