I have a mk5 inj stock, which has been stiffened with glass cloth, and layered epoxy ,which encase hard foam "box" -more accurately, "coffin shaped" cores.I roughed all surfaces, and made communication holes between all the compartments. Used "acraglass"w/glass filler for the
base coat, than topped this with many thin layers , followed by the foam "coffin boxes",this brought the bedding up to 3/16" of normal barrel channel.Some additional
drill work (8, 3/16 holes at 45 deg along each channel side)was done to anchor the layers of fill(4 thin coats) and the final bedding -full length,using the pressure points, and taped/release agent applied to the barrelled action as a cast guide. Additional opening was done at 4 corners of the action,and action screw openings were enlarged to epoxy pillar. This was quite an undertaking-took about a month, and result could not be deflected in a padded vise-a whole lot stiffer. A little fine tuning of the forend press, and
the group reduction was about 1/2 to 3/4", from 1-1 1/4" to 1/2"to 3/4" consistantly, which may not meet laser stats, but **** sure works for me.If your not familiar somewhat with glass and epoxy, I have to say , I wouldn't recommend,
unless you are into tweaking things for improvement-some thing I'm somewhat obsessive about. I used an adhesive primer over roughed exterior, followed by flat camo base colors, topped lightly with some trunk "speckle type"spray,
and sealed with matt acrylic for the exterior finish.No comment on the mental indications here! /ubbthreads/images/graemlins/cool.gif
