How to Tune a Compound Bow (Paper, Walk-Back & Bare-Shaft)

Do I even need to paper tune, or can I skip straight to bare-shaft or broadhead tuning?

Plenty of experienced hunters skip it. The common line on the forums is blunt: for a hunting bow, broadhead tuning is the only step that's truly mandatory, because broadheads on fletched arrows are what you actually shoot. Paper tuning is a fast, close-range way to get your rest in the ballpark and to see a problem at a glance — a nock-high tear and a left tear tell you different things — but on its own it's "only halfway there," since field points fly forgivingly. A sensible order: set the bow to factory specs, paper tune for a rough centershot, refine with bare shafts, then confirm with broadheads. Beginners get the most out of paper because it shows the problem visually; veterans often go straight to bare shaft and broadheads.

I've got a left or right tear that won't clear no matter how I move the rest. What am I missing?

If the rest is already near factory centershot and you're still tearing sideways, the rest usually isn't the culprit. Work through it in order. First, the shooter — grip torque and a draw length that's a touch too long both throw lateral tears, so have someone else shoot the bow to rule yourself out. Second, arrow spine — a shaft that's too weak or too stiff for your setup tears sideways and no rest move will fix it. Third, cam lean, where the string meets the nock at an angle; on a hybrid or binary cam that's a yoke-tuning job (twist one leg, untwist the other by the same amount so you don't change cam timing). The forum rule of thumb: if you've moved the rest more than about 3/16 inch off the factory mark chasing a tear, stop — something else is wrong.

Do I actually need a bow press, or can I do all of this at home?

Most of what tunes a bow needs no press at all — rest windage and height, nocking point, sight, and on many bows the draw-length module. A press only comes in for cable and string work: cam timing via cable twists, yoke tuning for cam lean, or swapping a string. Hobbyists do buy portable presses, but fitment varies — Bowmaster brackets sometimes need grinding for split-limb Hoyts, and some high-poundage or limb-stop bows shouldn't go in a portable press at all. If you're not certain your bow is press-safe, that's the one stage worth handing to a shop.

Why do my broadheads hit low and left of my field points, and how do I bring them together?

Fixed-blade broadheads act like little wings, so they exaggerate any imperfect arrow flight and steer toward wherever the arrow is actually pointing at launch — usually low, often off to one side. Fix the flight first: tune until a bare shaft hits with your fletched arrows, which normally pulls the broadheads in too. Then chase the broadhead group with tiny rest moves — heads hitting low, raise the rest a hair; hitting left, move the rest right. Check spine while you're at it; an over- or under-spined arrow is a common hidden cause (one shooter fixed it just by turning his poundage back up on an over-spined arrow). And if the bow took a knock on a hunt, that alone can throw broadheads off even when field points still group.

Real disagreement here. One camp keeps paper tuning as a quick diagnostic that gets the rest close and flags nock-height versus windage problems at a glance. The louder camp argues it's "only halfway" — field points fly too forgivingly to trust — and goes straight to bare-shaft and broadhead tuning, which is what a hunting setup lives or dies on. Most agree paper is most useful for newer archers learning to read a tear.

Broad agreement that rest, nock and sight tuning are DIY, but anything involving cable twists — cam timing, yoke tuning, string swaps — needs a press, and that's where most people send the bow to a shop. The dissent comes from hobbyists who've bought a portable press, with the standing caveat that fitment and press-safety vary by bow.

When a tear won't clear, the consistent advice is to stop moving the rest and look at form (grip torque, draw length) and arrow spine first. Walking the rest far past factory centershot to force a clean tear is treated as a red flag that the real problem is elsewhere.
