learned this one years ago while doing canvas on wood boats.. and recently fixed the mounting screws on the underside of of a couple kitchen chairs..
The wife was re-installing the cushions on a couple chairs when she stripped out the screw holes on the wood seat.............
simple fix........take a couple tooth picks, dip them in elmers glue and tap them into the hole, and break off whatever is hanging out.. give them a few minutes to set up and re-install the screw..
It also works on those old wood boats where the snap studs pull from the wood..
By the way, wood match sticks will work as well.......
Good tip Randy. Thanks.
