Stock duplication

[B. Dudley]

In regards to duplication, your question is a bit loaded. Depends on what you mean by precision. Are you talking about a drop in fit? You will be very hard pressed to get that, especially with a hand fitted gun like a Parker. The only way to come anywhere close is if the actual original stock is duplicated. And even then, any duplication will require hand fitting of the action and final shaping of the outside.
I mostly duplicate stocks as required for the restock jobs that I do on a one off basis.
My normal process of duplicating is to leave the inletting a hair undersized and the profile about 1/16 to 1/8" oversized. The rest of the work is done by hand.
My machine is basic and get the job done for what I do.

Beware of commercially purchased off the shelf Parker stocks since they will most likely not fit very well. Unless the duplication is of your actual stock.
