A (rifle) barrel vise.

One of our machining students is a skilled target shooter and reloader who wants to get into gunsmithing.  An essential item, along with an action wrench (which is the next project), for serious rifle action work and rebarreling is a barrel vise to install and remove the barrels.  While these are commercially available, the good ones tend to be somewhat expensive, while the less expensive units fit only one size/taper of barrel or tend to damage the finish. The student opted to make his own barrel vise, not only saving money for other gunsmithing tools but gaining valuable experience, while incorporating the desired features of several commercial units.  This version will have a 2 inch diameter bushing hole.  2 inch diameter aluminum bar stock is widely available, and can be easily fabricated to match  any barrel diameter and taper eliminating the possibility of marring the finish.

some commercial barrel vises can be seen at:

Using a short screw machine length drill to drill the first part of the bolt hole.  The shorter screw machine length drills have less tendency to walk or wander than the regular jobber length drills.  The students are encouraged to use these where possible.

Because of the depth of the hole, a jobber length drill was required to complete the hole.

Long stringy chips are a safety hazard and the students are exceptionally careful 
when drilling to clear the hole to limit their length and to keep the work area clear.

 

Counter boring for a 1/2 X 13 SHCS using a 3/4 inch 3 flute end mill.  Not the correct size but what we had available. See the next picture for how we cleaned the heads up to fit.

Using the milling machine as a lathe to clean  the outside diameters of the clamp bolts up with a carbide tool.  No extensive metal removal, just taken down to bright metal.  A common Dobby pad was used to deburr the edges and polish the heads to a high gloss.
