Welcome to Blake Barrel and Rifle

History and Drilling Process -

Blake Barrel and Rifle was re-launched in 2018. The business was actually started by Robert Blake in 1966. In 1969 Robert stopped doing gunsmithing and making single-point cut-rifled barrels. He transitioned to doing industrial work, and less work for the public. After all those years he and Dave Blake kept the barrel-making equipment in storage. They kept the gun-drilling machines in the shop as they used them to drill long, deep holes in anything from aircraft parts to electric motor rotors. In 2012 we got the diamond single-point, sine-bar rifling machine out of storage, along with the Pratt and Whitney double-spindle reaming machine. We then completely rebuilt and updated the equipment. We modified the gun-drill to be a counter-rotating drilling system. What that means is the drill spins at about 20% of the rotational speed, and the barrel at 80%. The counter-rotation keeps the drill on the center axis of the barrel more precisely than just rotating the barrel, or just rotating the drill. We are able to consistently drill holes in our barrel steel (primarily 416R) that at the end of a 33.25″ blank that is only .005″ off of center axis. We then ream the barrels to be .0004″ below desired finish bore size. After the reaming process we mandrel-hone the bores to be .0001″ below finish bore size. This process eliminates reamer marks in the barrel bore. Therefore very minimal lapping is needed after rifling to remove any tooling marks. We then rifle the barrel to any twist rate we like. With a fine lap after rifling, the barrel has no tooling marks and all surface metal is flowing in the direction of the twist of the rifling.
