Bolts / spine testing question

Post by exocet200hunter »

Hey everyone,

For those custom bolt makers here is a question : when checking the spine for stiffness do you check before or after inserts are installed ?
Thanks

I check mine before I install them.

I do it after inserts are installed. Reason being "spine" line may not be straight and the inserts "could" move where the exact center spine is. Have found that it can actually spiral/twist down the shaft.
