How do I fix loose tenons?
I learned my lesson the hard way: Mortises first, tenons second. But now that the mistake has been made, how can I salvage tenons that fit too loosely in a mortise?

To add wood back to the cheeks, Wyatt, simply follow the steps, above, and check the fit again. If the tenon needs more bulk, repeat the process. Cheeks now too chubby? Thin them equally with a sanding block or shoulder plane until the tenon fits snugly.
