I have a corner in the cellar of my home set aside for repairing speakers. Most of my repair work is done there. Some of the larger speaker repair/restoration jobs are done on the first floor.
Here is picture of my work bench. There is a darkroom timer (top center) that's left over from a darkroom I once had in that same spot. On the left side of the pic, a set of plastic clamp rings can be seen. They are used with spring clamps to hold down fresh refoams and/or when gluing down gaskets.
Below that is a scan of my reconer's certificate from the PLRA.
