What is the IDOD, what does it do?

The IDOD name means, ID and OD meaning it cuts the Inner Diameter and the Outer Diameter of the case neck. When you cut both the inside and outside in one operation, this eliminates any "donut" that wants to naturally form with conventional mandrel type turning systems that have been out for years. It also ensures there is little to no case neck thickness variation that you would see with just cutting the outside of the neck, no specific mandrel size expander prior to turning, and no case lube needed as there is no friction of the conventional mandrel type turning. When you cut necks on a mandrel type turning lathe, you fight the balance of having too much clearance from the neck and the turning mandrel and having the case "wobble" on the mandrel and not give a consistent cut. You also can have issues where you don't have enough clearance and your case is too tight on the mandrel and creates heat and friction to where you can't achieve a consistent neck thickness all the way around. You also have to use lubrication when turning this method, but with our IDOD, you do not need any lube.

If this is the case we will contact you sooner to let you know your machine will be shipping out early. The price for the IDOD is $2099.99 + shipping. This includes one case holder of your choice, one shoulder angle cutter, and all accessories required to operate the machine.

Case Holder Fitment and Full Inside/Outside Neck Clean Up

We recommend turning your brass in either the new or fired state with no further brass prep. In these states the neck to body run out is its most minimal. When brass is run through dies, expanded, or other forms of brass prep the neck can be unintentionally misaligned from the body of the brass.

You can turn your brass in any state of your choosing but the most important thing to keep in mind to achieve full clean up around the case neck is that the neck of the brass needs to be concentric with the body of the brass. This can be checked on a concentricity gauge.
How the brass is held in place by the case holder is by the taper of the case. A case holder for new brass is going to be based on the manufacturer's taper of the brass. All manufacturer's are similar but may vary some and can require separate case holders for different brands of brass. Fired brass changes the manufactured taper and forms to the inside of your chamber, this meaning that case holders must be made for your specific chamber and brass is required to be sent in for proper fitment. 
Your neck to body run out when checked on a concentricity gauge needs to be less than the amount you are cutting. (Ex. If your brass is checked on a concentricity gauge and your neck to body run out is .004” and you are only cutting off .002”, your brass necks will not have 100% clean up.)  
If you have .002" neck to body run out in your brass when checking it on a concentricity gauge, you would need to cut minimum .002" off to get 100% clean up. For example, when the 6.5 x .284 Lapua brass is expanded to 7mm and full length sized with a bushing less die to keep the neck to body concentric, it is approximately .014" - .0145" neck wall thickness before turning. When turning to .0125" or thinner we always get sufficient clean up.
