I have two mannlicher/full stock blanks (black walnut that I cut 30-odd years ago) that I want to bandsaw in half (split down the middle) and laminate a thin walnut board in between the halves for improved stability. I'm sure they're way oversized in the butt section, so I would like to take off excess wood to make it easy for the stock profiler and less work for the bandsaw. Anything like "standard" dimensions for full length stock blanks? Thanks!
