How long is the rental term?
You have seven (7) days from the time it arrives at your address to use the tool. As soon as you are finished with the tool. Please return it on time so that it will be available for the next renter.
Where are the Headspace Gauges?
Headspace gauges are rented by selecting the combination of reamers and/or gauges you need from the dropdown list in the red box that reads “Add Reamers/Gauges” when your looking at any specific caliber reamer. We aim to keep it simple! Don’t know what a headspace gauge is? Click Here.
Can you send me a print?
It’s not as easy as you think. Reamer makers provide a standard print for the chamber reamers they make. Prints have tolerances that are extrapolated by the reamer maker from SAAMI standards. So a reamer can be within tolerance and not exactly match the print. Prints provided by reamer makers are generic in that sense. We do not have prints specific to any tool. All we have are either SAAMI prints or prints given us by the reamer maker. Imagine you had over 1200 reamers to take care of along with more than twice that many gauges and hundreds of other tools that we rent out. Just sayin…
What is the Neck diameter and/or Freebore?
Our reamers are standard for caliber unless otherwise stated in the price list or on the web site. Otherwise the throat and neck will be standard for caliber. Nobody reinvents the gun industry by changing such details. Reamer makers normally apply standard for caliber freebore length, i.e. that means if the designer of a wildcat does not specify a throat, the reamer maker will give it what they would put on the factory equivalent. Imagine that 25 people a day asked you this…
Will I receive a sharp reamer?
Yes, our success as a company will always rely upon repeat clientele!
How does 4D assure the quality of it’s rental tools?
Each tool is inspected under magnification upon return from rental to insure that it is clean and sharp. Reamers are then placed in a plastic shipping tube and an inspection seal is attached so that we know each tool has been properly inspected before it is shipped out.
What all is included?
Everything is ala-carte. You get to pick and choose only the tools and items that you want, this saves everyone money!
You already charged my card?
When you order from this web site the cart will automatically charge your credit card for the rental and shipping at the time that you place the order. If you have questions about our rental policy; Click Here to read the rental agreement.
I left a message…
Email is always the best way to communicate as we can respond at any hour. We do check message as often as possible however, business hours are limited so it can take longer for us to get back to phone messages. Order volume is high so we work to ship internet and fax orders before we get to phone messages. We want to get the tools out the door as soon as possible, this is what clients tell us is important to them. Fax # is 406-890-6341
If your message is, “Call Me” you will be low priority. Please leave a message that indicates what you need if you want a quicker response, be specific. Again, Email is best!
Where do I return tools?
Scroll to the bottom of the page, our address is displayed on all pages of this site. Its also on the price list and invoice we mailed with your order.
Do you send Email notification when the order ships?
Yes, if you provided an email address when ordering the tracking info is sent to your address automatically. The return address is from the USPS unless you requested another shipping method. Please check your spam filter before you ask for tracking info.
When you see that your order reads as “Completed” on the web site or in an email that only means that the credit card processor completed the transaction. You will receive a separate e-mail with tracking information when the package ships, this is why you should supply a correct email address.
We have seen a lot of email addresses with added letters or figures that are obviously placed there to cause email failure. When you do this do not ask why you were not notified… Should be self explanatory.
I did not use the tool, can I have a refund?
When you place an order for a tool, you are purchasing the time to use it. Since the tool is out of inventory for your order we cannot use that tools to serve another client. You should only order tools you know you really need. More details about renting tools: Click Here.
I’m scared to death to rent tools!
No need to be afraid, we have been doing this for a very long time. In the average year only about 2% of the tools are either lost or damaged due to accidents, negligence or shipping problems. So it’s not a big problem. If that does not relieve your fears about the possible costs, then check out our Rental Protection Plan. You can control the cost.
Which way do I turn this thing?!?
All reamers that 4D offers for rental are right hand or clock-wise cutting.
In other words, all reamers should be turning to the right. If the barrel is in a lathe the barrel will run in normal forward direction or counter clock-wise.
We have some videos prepared that help explain the use of gunsmithing tools, click here to see what we have.
Why is this important?
Because running the tool backwards will damage it. Damage will likely require a professional resharpening, your deposit would then be forfeit to cover that expense. Not only that but it will take about a hundred years to ream a chamber in reverse and the quality of the chamber will be very poor.
Do I need to use a lubricant when reaming?
Absolutely, we recommend Brownell’s Do-Drill, Conoco makes a cutting oil called “Spectrum” These are two oils that will work well, there are others. We sell Tap Magic which will work to ream a chamber.
I did not get a sharp reamer?
Highly unlikely as we take exceptional care to see that they are in good shape. A couple of things that may make you think the reamer is dull:
- Barrel made of much harder alloy than normal or heat treated to an abnormal hardness.
- Semi-Auto pistol barrels are often harder to deal with wear of the locking system.
- Chrome washed bore or chamber, High Speed steel reamers will not cut Chrome!
- Working by hand
- Turning the reamer the wrong direction (don’t laugh) clockwise is correct.
- Pilot too large for your bore, don’t force it.
- No cutting fluid, cutting oil is necessary!
If you feel the reamer is dull contact us immediately. Email is best for such conversations. We will help you resolve the issue in as short a time and as cost effectively as possible for all concerned.
Shogun Choke Tools, I think its dull?
We inspect these tools before they go out. If we suspect a problem or one is reported we cut a test barrel here in our shop. 99.999% of the time the tools are working correctly when inspected. The most common error we hear is trying to use these tools without first removing the fixed choke in the barrel, this is absolutely necessary.
These tools are very large in diameter and are cutting on a huge surface area. Cutting oil and power is required. If you do not have a lathe or some other reasonable way to power the tools we do not recommend using them by hand.
Naturally, the tap can by used with a large tap handle by hand.
These are High Speed Steel tools. They are not intended to cut chrome washed bores. Chrome will destroy the tool and you will pay for its repair. Know what you are working with!
Should I sharpen the reamer?
NO. We inspect the reamers it assure you are getting a sharp tool. Much of the damage we see to reamers comes from incorrect stoning or sharpening of the reamer. The client is responsible for the cost of repairs for such damage. We have a video on this subject on another page, click here.
Who pays the return shipping and insurance?
The client agrees to pay the return shipping. Be sure to insure the package as you are responsible for the tools until we receive them. We do not supply a return label.
Why don’t you supply a return shipping label?
In many parts of the country it may be difficult to use a specific shipper, so we leave it up to the client to choose the return shipping method to keep the process as easy and convenient as possible.
Do you sell Reamers?
Yes, they are strictly on a special order basis, we can often supply common calibers in a week or two, headspace gauges too. Email us with your requests.
How do I make a chamber cast?
We recommend CERROSAFE® casting metal, it is a low temperature metal designed for making precision casts of cavities. It’s properties are well known in the gun industry and reamer makers as well as gunsmiths will recognize the brand name. Simply follow the link above for instructions on use.
What is the difference between Solid and Floating Pilot?
Solid pilots are integral to the reamer, they do not move and are ground to the common SAAMI dimension for the given caliber. Floating pilots or bushing pilots are a precise slip fit to the pilot area of the reamer, they can be interchanged to allow for the best possible fit to the bore.
Which is better? That is a subject of ongoing debate in the gun trade, about 50% of clients prefer one or the other. Floating pilots have the advantage of versatility, Solid pilots do not run the risk of stacking tolerances. Both types of pilots will produce excellent chambers.
Do you send me a selection of pilots with the reamer?
As stated in the Rental Agreement; We do have a limited stock of bushing and it is your responsibility to tell us what diameter you need.
No we do not send you an assortment, if you want extra pilots you can order them, Click Here.
I think you sent me the wrong reamer?
I reamed a piece of nylon with it and my ammo won’t fit?
That’s because Nylon is not steel, it springs and moves away from the reamer.
It’s too long?
Sometimes the reamer maker uses a long reamer blank for a short cartridge, it’s not a
problem. The length of the reamer blank has no correlation to the chamber length;
headspace gauges are used to establish the actual depth of the chamber.
How do I use Ackley Improved Headspace Gauges?
In rimless bottleneck cases you will use an Ackley ‘Go’ gauge. The ‘Go’ gauge for the parent cartridge will become the ‘No-Go’ Gauge. Why does this work?
Ackley was pretty smart, he realized that if he set up the “Improved” chamber shorter than the factory chamber that you would be able to fire factory ammo. Because the brass is slightly crushed by the neck/shoulder junction of the new shorter chamber it is held tight against the bolt face for firing. That is why you must set the barrel back when rechambering for a rimless bottle necked cases in Ackley Improved configuration.
Why no Ackley gauge for rimmed or belted cases?
Simple, these cases are headspaced on the rim or the belt, so the shape of the chamber has no affect on headspace. The case is trapped between the boltface and the forward edge of the rim or belt, so when you fire the cartridge it simply forms to the new shape of the chamber.
Do you Ship outside the U.S.?
Sorry, we do not ship outside the U.S. NO.
