I'll third that motion! CA works pretty good for a fast fix for stripped screw holes - not as good as plugging and drilling, but it can work quite well. I usually jam a couple of splinters of hardwood (something a little soft like mahogany) into the hole with CA and screw the screw in. I put the accelerator directly onto the screw - I have found that you can easily break the bond between the CA and the screw - remember, CA doesn't have very good shear strength. In this particular case however, a significant part of the problem is likely related to "All the screws were stripped in the dowel in the rail." Dowels do not belong in a hammer rail - likely someone "fixed" stripped screw holes in the past by drilling and plugging with dowels - as Debbie pointed out, the proper repair is done with maple plugs, not dowels. This hammer rail either needs a new rail or needs the dowels drilled out and replaced with plugs. Terry Farrell Although, truthfully, the stripped hole should be drilled and plugged, there are many instances where this is not possible. Remember, people, I'm a player tech <G>. A good way to create *new* thread in a wood hole is to first spray the screw with your favorite mold release. Then with a toothpick as an inserter proceed as follows: cut a small strip of pouch leather, fold it in half lengthwise over the tip of the toothpick, carefully coat with med CA (or put a couple teeny drops in the screw hole). Insert leather into hole using the toothpick to guide it to the bottom of the hole. Make sure your strip is long enough to create *tails* at the top, outside of the hole. Hold these tails apart and down to the surface as you thread in the screw. Let set five minutes or so. Remove screw, trim away excess leather tails. New threaded hole. BTW, cover your fingers that handle the tails with masking tape! Debbie L. >I beg to differ. CA works wonderfully for fixing stripped screw holes.
