Action Bolt Bore Reamer/Mandrel

Price: $285.00

This multi purpose precision tool is priceless to the accuracy smith. The tooling is a must for accurizing actions and sleeving bolt bodies. It cuts the cost of having .0005 increment mandrels or stepped mandrels for multi diameter bolt bore raceways. Without a properly fitted manderal, a canted false axis is set for the bolt bore, and askewed machining will result!

The precision ground reamer/mandrel takes 4 weeks to manufacture. From it’s start as a blank mandrel, with rough out to hardening , onto cryo then aging to final grinding, this is state of the art tooling.

To start, the reamer is helical for interrupted cuts down the bolt bore. As with a .703 reamer/mandrel that is going to be used to rebore the raceway, it has multi position interchangeable bushings. This is to make sure you rebore down the center line of the raceway and establish a true and concentric raceway.

As an example take a Rem. 700 action. The bolt will be receiving sleeves as part of the accurizing job. The action rear bolt bearing area has a I.D. of .7015. You install one .7015 bushing in this bearing area. Next to the front bearing area, and this I.D. is .7025. Install a .7025 bushing. Now from the rear of the action, slide in the mandrel section in front of the helical section of reamer through the center of the bushing. As the reamer is advanced through the action it pushes the bushings forward. As it advances it re-cuts the bolt bore to .703.

The rear portion of the reamer is a solid ground bearing area of .703 as with the reamer section. The reamer maintains alignment on its entire cut from back to front.

This is now a fitted manderal in perfect centerline of the bolt bore raceway. This is used then to dial in the action in the ACTION BLUE PRINTING JIG. Life is good.

There is more! What if the customer doesn’t want the action rebored for bolt body sleeves. But wants an accurate blue print of the action. So simple and cost effective! The Winchester action is worn. The rear bearing area is .703 and the front bearing area is .707. You fit the bushings as above in the front & rear bearing areas. Slide the manderal in from the front and use the rear reamer bearing area as the dial indicator surface for two dial indicators after mounting in the ACTION BLUE PRINTING JIG.

Chambering Flushing Systems

You  routinely work with match grade $200 and $300 barrel blanks for your own use and for your customers. The match grade barrels with which you work are the output of meticulous craftsmen, and now your gunsmithing must be of equal quality and precision. Your chambering will take several hours of exacting work, using match grade chambering reamers, and multitude of dial indicators.

The time has come for you... to stop blowing sharp , abrasive metal chips out the muzzle end of that expensive match grade barrel while you are cutting the chamber. (Many barrel makers oppose the use of abrasive bore cleaners; but here you are, blithely blowing steel shrapnel down the bore, under pressure!) And pushing the metal chips out with a patch and jag comes from the school of metalworking barbarism.

A host of accuracy-enhancing advantages... The reamer is constantly being lubricated and cleaned... The chips are flushed out the back of the reamer  lands.. The pilot bushing is constantly being lubricated... Bore damage from chips wedge between the pilot and bore is eliminated... Chip ringing of the reamer is likewise eliminated... A constant fluid supply for chamber polishing... Abrasive grit exits the chamber, not through the barrel bore... The reamer is kept cool... No dimensional changes to the reamer.. Works with oil or water base cutting fluids (no need to change from the fluid that you now use.) This is what you must use, to properly use carbide reamers.

Start !!! using G.T.R.'s chamber flushing system. Three models available for lathe chambering. Chose the system that matches your lathe setup for chambering.

MODEL BTS (Barrel Through Spindle)

Price: $109.95

This barrel adapter was designed for the gunsmith with smaller lathes in mind. If your chambering method is to mount the barrel through the spindle bore, and indicate the chamber end at the chuck, and the muzzle out the rear of the spindle with a spider.THIS is just what your looking for. The BTS mounts on the last 2.5 inches of the muzzle end of the barrel and works on barrels from 1/4 " to 1.3". Also .14 through .50 cal. with no parts interchange. The time to install is about 15 SECONDS! This unit just WORKS! And IT DOESN'T LEAK!

MICRON

Price: $80.00

Replacement filter price: $5.50

This is a one micron filter kit. It is compatible with both water soluble and oil based cutting fluids. The filter element is disposable and made from spun polypropylene, so it won't dissolve or burst under pressure.

Jigs

Action Blueprinting Jig

Price: $199.95

This is the best thing to hit the bolt rifle accurizing market for actions! This is not a sacrificial collar that only does round style receivers. It’s a jig that works on round, square, flat bottom-round top, long, and short. To date all Remington bolt actions, long and short. Winchester's long and short. Sako’s and I mean all of them. Savage’s long and short. Brno, Marlin, Weatherby, Ruger M77, etc.. The one that has not worked yet is a Ruger MK II 77 with the investment cast trigger hanger.

The action jig is held by a 4 jaw chuck . The rifle action to be accurized is held inside the jig. With 4 front and 4 rear centering adjustment pads, the rear having two locations for long & short actions, the center-line axis of the bolt bore raceway can be perfectly aligned with the rotating axis of the lathe. All single point machining of the receiver face, lugs, and threads will be concentric.

Perfection is obtained by the use of two dial indicators to set perfect alignment. One placed on the alignment manderal at the reciever face and the second placed at the end of the manderal . When both dials indicate 1/10,000 or less runout at the same time and in the same rhythm, perfection has been accomplished not desired. Once dialed in you DO NOT CHANGE OR MOVE the setup. All machining will be in perfect relation to each other and all to the axial center of the bolt bore raceway!

With the once accepted method of turning a collar with the action between centers and then mounting in a 4 jaw and indicating only the collar in, two devastating accuracy robbing mistakes have been made. #1 you have moved your setup form your collar cut and will be machining from a secondary setup. You have lost center line alignment. #2 you dialed in the collar around the action in a four jaw chuck to 1/10,000 or less and believe you have achieved alignment. Here is the fly in the soup. Are the jaws on your chuck perfectly parallel with the rotating axis of the lathe to 1/10,000. If you put back or leave the mandrel in the action and check the runout at the end of the mandrel, you will with a sinking feeling see the action rotating in a progressively larger cone as you move away from the collar you dialed in on. The problem with the collar system is no way to take out this misalignment in this type setup. ALL MACHINING WILL BE INACCURATE & ASKEW FROM CENTER LINE OF THE BOLT BORE!

Recoil Lug Lathe Jig

Price: $80.00

After  single point re-cutting the action threads, the barrel tenon threads will be a larger diameter. Meaning the I.D. hole in the lug will have to be opened up to give appropriate clearance. In the past smiths set the lug up on a mill, dialed it in and machined for clearance. Accurate but very time consuming for an operation that makes you no money. Just part of the job.

This jig works in a 3 jaw chuck. It takes about 5 minutes to clamp the jig in a 3 jaw, clamp and center lug with the tailstock, and then bore diameter. I use a standard oversize diameter for all my rebarrel  tenons in the lug area so when I setup to do one, I do every lug in the shop at that time.

Bolt Truing Collar

Price: $25.00 for a three pack

This  collar is seamless and locks over the bolt lugs. You don't have to worry about the marring of the bolt body by the tips on the steady rest.

It allows you to turn a true surface for the steady rest tips to ride on to give a solid hold for clean true cuts.  Sold in 3 packs.

Reamer Holder

Price: $80.00 (includes #2,#3, or #4 morse center)

Price: $95.00 (includes #5 morse center)

This reamer holder is unique in that you can dial  in the pilot to enter the bore of the barrel by adjusting the three thumb screws. Once dialed in the reamer is supported for no drag withdraw and plunge of the reaming operation. The tension springs give a constant force to the reamer to stay  seated on the dead center in the tail stock. The holder comes with the dead center.

The greatest advantage is the 360 deg. hold on the reamer. Ever try to tap a straight hole by turning and holding onto one handle of a tap handle? The same thing happens when reaming. The reamer tips 90 degs. of applied pressure and the pilot rides hard on the top side of the rotating bore.

Radial alignment  is corrected with this reamer holder. Axial alignment is not. The axial displacement in the ram of the tailstock will provide what is needed. That is if the correct alignment procedure has been preformed to the lathe and tailstock for reaming operations, i.e. chambering for rifles! Tailstock alignment procedure for turning a true shaft IS NOT the same thing and will never give you true center lathe axis thrust for chamber reaming!

Helpful hint: If you don't know how, or  your tailstock simply can't be realigned, then one of the manufactured floating reamer holders on the market is what you will need to purchase to correct axis misalignment and give you the ability to ream straight chambers.  But, on a floating reamer holder, nothing guides the back of the reamer, it goes where it wants. If the reamer starts crooked, it stays crooked, no matter how the barrel is lined up. It's up to you, my system where you know you're straight, or the others where you hope you're straight

Rods

Indicator Rods

Price: $35.00

Indicator rods use removable bushings just as reamers do. Bushings by Pacific Precision, JGS, Henrickson, Francis, Forgreens, and Elliot will fit. These rods are for chambered barrels. If you chamber with the barrel held by a 4-jaw chuck and the muzzle extends through the spindle bore, and are trying to indicate the bore in for a rechamber , you found the answer.

The rod centers itself with the pilot bushing and a 3 deg. taper ground onto the precision ground mandrel . So even though the chamber may or may not be cut straight, you know where the bore is and only indicate to it , and cut a new chamber .

Range Rods

Price: $35.00

Range rods are for indicating non-chambered barrels. They are built with the same features as indicator rods except they have a 1.5 deg. taper , and are shorter in length.

Action Blueprinting Video

Price: $58.00 (includes shipping)

Only Available in DVD Format

Length: 2 discs / 4hrs. long.

No other video ever made comes close to this Hi-Tech in depth look at what is involved to blueprint an action. This video is not candy coated.

It reveals the inherent gross misconceptions of action truing with facts and dial indicators.

All machining is single point, including the recutting of the threads. An in-depth instruction section on setup of the threading tool bit and how to pickup the internal thread in an action for recutting for professional truing of threads. Not the back yard butcher method of using a tap!

The setup of actions in this video are explained in depth, then shown with dial indicators. FACTS are the only subject in this video! Not what someone believes in. This video shakes the foundation on what pretenders, self proclaimed machinists preach, but have no concept on axial alignment. What someone thinks and what someone knows are two different ball games. Hard ball is played in this video. Knowledge is the umpire. If the truth scares you don't purchase this video.

The fresh machined action without any lapping to the lugs, wipes 100 % of magic marker off of the recoil lugs in the action. With a 5 digit after the decimal depth micrometer, the action measures to within 50 millionths, or 1/2/ of 1/10,000 across the bolt face from the reciever face.

Tool room precision is the only subject presented, not B.S.

Bolt Sleeving Video

Price: $55.00

Only Available in DVD Format

Length: 2 Discs 2 1/2 HRS.

The start of this video shows the bolt  lug deflection off of the of the reciever  lug. This when seen, will open your eyes to the next step in accurizing. Also it makes it easy to  understand and explain to your customers.

Next the use of the action bolt bore reamer/mandrel is shown and demonstrated on an action that is being blue printed and double sleeves on the bolt.

Then  the nitty gritty of sleeving a bolt body. All setups for machining are shown from start to finish on the bolt. A double sleeve  is what is installed, and how to setup so the firing pin hole is held dead center of the chamber.

Sleeving bolts for actions that are not having the bolt bore raceway rebored is explained. Also what and why when sleeving a competition action, veers that elk rifle. The tape ran out and tape two was made to properly finish up the small details that only through time, money,and experience I have learned. THIS VIDEO IS CUTTING TECHNOLOGY.

Tailstock Alignment for Reaming Video

Price: $41.00

Only Available in DVD Format

Length: 50 minutes.

As mentioned above, there is a required alignment procedure for tailstocks. Along with this , to achieve repeatability when moving the tailstock for  depth of cut , like head space readings, the tailstock has to come back into axial alignment when slide back up the barrel for resuming the reaming operations.

This video shows how to dial in the tailstock along with the why the turning of a shaft for alignment is fighting and ruining all your efforts for flawless precision in the chamber reaming  operation.
