Just one. Win M70 Fwt from the early 90's I did last winter. Had a little spot of hot glue looking bedding from the factory and I always wanted to try it. I got stockmakers screws, clay, and Acraglas from Brownells. Hogged out the stock, packed in the action voids with clay, went for it. I did the whole action, not just the lug. Pretty easy, just have to be careful and thorough. I used aluminum pillars and Acraglas gel for a stress free perfect fit in theory. Turned out good, fit is perfect, and I've eliminated a variable in accuracy.
