Frequently Asked Questions
Building Arrows
How do I cut carbon arrows without splintering them?
To cut carbon arrows cleanly, use a high-speed arrow saw with a sharp, fine-tooth carbide or diamond blade (like the modsaw). Rotate the arrow slowly while applying light, steady pressure into the blade rather than forcing the cut. Supporting the shaft close to the blade will dramatically reduce splintering. After cutting, lightly square the end of the shaft to ensure proper component alignment.
What blade type is best for aluminum vs carbon arrows?
Carbon arrows cut best with diamond-coated blades, like the modsaw uses, designed specifically for composite materials. These blades stay sharper longer and reduce fraying. Aluminum arrows can be cut with fine-tooth metal-cutting blades, but many archers use the same blade for both materials to maintain consistency.
How much money can I save building arrows myself?
Building your own arrows can save $3–$8 per arrow, depending on components and brand choices. Over a dozen arrows, that often translates to $40–$100 in savings. Beyond cost, DIY arrow building allows for tighter tolerances, easier repairs, and the ability to tune and customize arrows exactly to your setup—benefits many serious archers value more than the savings alone.
What safety gear should I use when cutting arrows?
At minimum, wear eye protection to guard against carbon dust and debris. A dust mask or respirator is strongly recommended when cutting carbon arrows, as fine carbon particles can be harmful if inhaled. In addition, we recommend using a vacuum to keep carbon dust away. Keeping hands clear of the blade, securing loose clothing, and using proper arrow supports further reduces risk.
What mistakes should I avoid when cutting carbon arrows?
Avoid cutting arrows to inconsistent lengths, using a dull or incorrect blade, or rushing the cut. Always rotate the shaft during cutting and apply light pressure to prevent splintering. After cutting, square the shaft ends so inserts seat flush—unsquared ends can cause wobble and hurt accuracy. Finally, don’t skip spin-testing after assembly to catch alignment issues early.
Modsaw
How are ceramic bearings better than steel bearings?
Ceramic bearings have a longer spin time, are more resistant to weather and humidity, and are self-lubricating.
How long will the blade last?
Our diamond coated blades last the typical DIY archer a lifetime.
What does the nock-in measure?
The nock-in measures the distance from the throat of nock to the tip of carbon.
Can it cut aluminum arrows?
Yes! The modsaw is capable of handling aluminum, carbon, FMJs, and wood arrows.
Can I purchase an upgrade for my Modsaw to get the features of a Modsaw PRO?
Unfortunately, the arrow saws are not compatible; therefore, there is not an option to upgrade a Modsaw to a Modsaw PRO.
Modsaw PRO
What's the difference between the Modsaw and the Modsaw PRO?
The Modsaw was built for the DIY archer, while the Modsaw PRO is more geared toward bow shops and those who build a high volume of arrows. A few key upgrades of the Modsaw PRO include:
- a brushless motor with a lifetime warranty
- a larger 2" blade
- an optional foot pedal
- automatic squaring on linear bearings
- an improved rear rest on a track system
What's the benefit of an automatic squaring system?
Automatic squaring on the blade improves efficiency. Instead of manually squaring on sandpaper, automatic squaring cuts down on the time needed per arrow, especially important for bow shops and high-volume arrow builders.
How does the optional foot pedal work?
Our optional foot pedal allows the user to either use the on/off functionality powered by the pedal or a fully 'on' saw through the thumb switch. Swap between the two depending on what suits your workflow best!
Can the Modsaw PRO handle all arrow types?
Yes — it’s built to cut:
- Carbon arrows
- Aluminum arrows
- FMJ arrows
- Wood arrows
Paper Tuner
What are the benefits of paper tuning?
Paper tuning allows archers to better understand how changes made to their bow can impact arrow flight. By paper tuning, an archer can make adjustments to ensure optimal arrow flight for target archery or bowhunting.
Does the tuner come with paper?
Yes, it comes with 30’ of paper!
What is the correct paper replacement size?
Our paper tuner only works with 13” paper rolls, sold here. We also sell 18” rolls that can be used with other brands of tuners.
