    Gunsmithing Trued action

    Dave, About how much looser from pitch diameter do you think is empirically sufficient to provide a good receiver to shoulder lock up? My first bolt gun barreling job was on a glued action, my brother's 30 BR. I downloaded the tenon print from the action manufacturer, got the chamber done...

    Gunsmithing Lathe for gunsmithing

    Yup, that was Mark's original design, I still have the V way mounted prox, just on the 1024, there is no room on the V way between the HS and the apron, so we had to settle on the pan mounted prox riding on a linear bearing. Though the little lathe is belt drive with a 2HP motor and a Hitachi...

    Gunsmithing Lathe for gunsmithing

    That looks a lot like Doc Jacobs' old system before he moved on to the ERL. The same system as on the JET 1024 except the proximity is bolted to the pan.

    Gunsmithing Piloted Finish Reamers: prebore or not?

    After dialing the bore, drill, indicate the area ahead of the neck, dial in the groove if adjustment is needed. Using a small carbide boring bar, I taper bore short of the shoulder in length and diameter. Run the finish reamer longer than headspace. Adjust tenon shoulder to headspace, thread and...

    Gunsmithing Question for LRI

    Chad, We just learned that BAT Machine will cease manufacture of their AR15 and LR308 barrel extensions, is this business something that might have a good margin putting your CNC capacity and capability to work? They still have extensions in the inventory, but looks like when these are gone...

The...

    Gunsmithing Ar receiver truing fixture

    I special order my competition barrel extensions from BAT Machine with 1.000 OD. On most receivers I have to slightly heat up the front end of the receiver and tap it into the BE. The competition BEs have 20 TPI threads and are 0.3 longer.

    Gunsmithing Ar receiver truing fixture

    Here you go. I used the same precision rod on both set up The bottom picture I use a rotating tail stock chuck and a mini spider. Why so many adjusters? I drilled/tapped the extra set while I had the spider in the super spacer. The rod is held by a copper ring in a set tru 6J to allow the rod to...

    Gunsmithing Threading bull barrel down to 1/2"?

    No issue. Done it many times on friends' weapons and on mine. Besides my dedicated Allen engineering AEM5, I use my Surefire 30 caliber can from 300WM to 5.45x39 AR and slew of 223s in between. I never liked the 1/2 x28 on AR barrels for service rifle competition, when the A2 flash hiders for...

    Gunsmithing Pre-contoured AR barrels

    Call J at Shilen and ask for a 26 inch blank, the breech end cut to 1.000, minus "0", plus 0.003 for 14 inches, and the balance at .750, minus "0", plus 0.003. Or to whatever length you prefer the two diameters should be, and what diameter you use for gas block. I just used .750 for example
