i have a walnut stocked rifle thats doing what stubblejumper describes. its free-floated with about a 1mm gap and you can actually see the stock warp and push against the barrel from the side, then go back to normal as it dries out in the cabinet.
is there anything you can do to prevent this or somehow lessen the warping? its an old rifle and a synthetic stock is not an option.
would drying it out, then a heavy 50-50 mix of turp/tung oil left to soak in real deep, then a half dozen coats or so of tung oil help seal the stock and prevent humidity changes?
Yes, but it takes work. If the wood warps when it gets wet the grain isn't straight or varies in density. So to fix the problem you have to interrupt the grain in the forend. To do this you make two cuts with a bandsaw straight down the forend avoiding the checkering if you can. Then you glue strips of walnut veneer in to the cuts using epoxy glue. Clamp, let cure, trim excess wood and glue, touch up checkering if necessary and refinish stock.
