The fore stock on my matched Gew98 broke under the barrel band. There just isn't a whole lot of wood in this area with the cleaning rod bore, nut and band spring mortise.
To correct this I bored a 0.625" hole into each piece of the stock to accept a dowel. The bore doesn't perforate the out surface in any locations. Initially I was gong to use a wooden dowel but felt there would be too little material left after boring and mortising to make a strong repair.
I opted to machine an aluminum dowel in this application. I left the surface of the dowel with sufficient 'tooth' to attain a good bond with the epoxy. The ends of the stock were soaked in acetone prior to epoxying to remove and oils that could hamper bonding. After bonding the stock with Acra-glass I machined the mortise for the cleaning rod nut.
200 rounds later it shows no signs of failing.
