As a Custom rifle builder let me put my two cents worth in. It takes a lot of time to make a good stock, and a lot of work so do not skimp on the wood!!!! For the most part it takes just as long to make a good stock out of plane wood as it does out of the nice stuff. If you are going to put the effort in then use a blank thea will give you something worth your effort.
I do not know your abilities but there is much more to making a stock then a piece of furniture, I am not knocking your tallents but there are differences and they spell the difference between splinters and a nice stock! If you have some questions feel free to call me at 207-938-3595
