Repairability of a TR fiberboard baffle?

Just picked up a sano 1970 Twin Reverb for $600 after some haggling. It's clean and good but the baffle has pulled off the screws that hold it to the cabinet.

Is there any way to repair the fiberboard? I really don't want to replace it with a plywood board. And the cloth, tolex and hardware are all in excellent shape.

Wonder if some mix of white glue and saw dust could do the trick?

Sure. Particle board is basically just sawdust, small wood chunks, and glue. A good quality yellow wood glue, such as Titebond would be better, but regular old Elmers would work. Just be certain it's good and dry before you sand it flush and drill it out.

Thanks Edward. Got the speakers in and they sound great. I think I can fix the board, it isn't completely ruined.

Larry Rodgers in Naples,Fla makes birch replacement baffles that are terrific if you decide that glue doesn't hold up the way you want...you could send him your grill cloth ...

Also, you can add some cloth or nylon webbing over the surface like a patch, infused with glue to reinforce the patches, and prevent splintering and chipping later.

Most people zip new screws into the front with finish washers

I'd just drill a few new holes in different places on the battens, and then mount the board from the back using sheet-metal screws.

I would suggest "Epoxy Putty" water based glues tend to be more of problem when trying to build up particle board.
