How to
Make a
Slingshot
A natural Y-fork, proper flat bands, a microfibre pouch, and tying tape. Step-by-step instructions used for generations — with a few modern upgrades that make a real difference.
Making your own slingshot is a rewarding project. This guide walks you through the build using a natural Y-fork and proper flat bands — the same method that's been used for generations, with a few modern upgrades to get you shooting straighter and harder.
Head outside and look for a hardwood branch with a natural Y-shape. Here's what makes a good fork:
- Symmetry — Both arms should be roughly the same length and thickness. Minor differences are fine, but a lopsided fork throws your aim off.
- Thickness — The arms should be about thumb-thick (15–20mm diameter). The handle can be thicker.
- Fork angle — A moderate V-shape works best. Too narrow and the bands crowd together; too wide and you lose power.
- Wood type — Hardwoods like eucalyptus are ideal and easy to find across Australia. Avoid softwoods like pine — they can snap under band tension.
Cut the fork slightly longer than you need. You can always trim it down.
Preparing the Fork
- Strip the bark — Use a knife to remove all the bark. This prevents moisture getting trapped and causing rot.
- Dry it out — Let the fork dry for a week or two in a warm, dry spot. Green wood works in a pinch but will shrink as it dries, which can loosen your band attachments.
- Sand it smooth — Start with 80-grit to remove rough spots, then finish with 220-grit. Pay special attention to the fork tips — rough edges chew through bands faster.
- Round the tips — Slightly dome the top of each fork arm for a smooth band wrap surface.
Apply linseed oil or clear lacquer to seal the wood and give it a polished look. Not essential, but it extends the life of the fork significantly in outdoor conditions.
The bands are the engine of your slingshot. Get these right and your DIY slingshot will shoot as well as anything off the shelf.
Option A: Pre-Cut Flat Bands
The simplest approach. Pre-cut flat bands are already cut to the right length and taper — skip straight to Step 3. Best option for your first build.
Option B: Cut From a Latex Roll
If you want to customise band dimensions or build multiple slingshots, cutting from a latex roll gives complete control. Use a band roller cutter for clean, consistent strips.
Recommended Band Dimensions (Beginner Setup)
Cut two identical bands. Consistency between the two sides is more important than exact measurements — if both bands match, your slingshot will shoot straight. Uneven bands are the number one cause of inaccuracy in a homemade slingshot.
Both bands must be exactly the same length. Uneven bands are the number one cause of inaccuracy in a homemade slingshot.
For a first build, use the OTT (Over The Top) method — it's simpler and more forgiving than TTF (Through The Fork).
- Place the wide end of the band over the top of the fork arm, with about 15–20mm of band wrapping down the outside of the arm.
- Hold the band firmly in place.
- Take your Amberbelt tying tape and wrap it tightly around the band and fork tip. Start from the bottom of the overlap and wrap upward, stretching the tape as you go. Four to five tight wraps is enough.
- Tuck the end of the tape under the last wrap to secure it.
- Repeat on the other side — make sure both bands are the same length from fork tip to where the pouch will sit.
If you have a band tying jig, use it here. It holds the band and fork in position while you wrap, making it much easier to get a tight, even tie. Especially useful for your first build.
The pouch sits at the centre of the band set and holds your ammo during the draw.
- Take your microfibre pouch — it will have a tab or hole at each end for the bands.
- Thread the narrow end of one band through the pouch hole (or lay it over the tab, depending on pouch design).
- Fold the band back on itself by about 10–15mm.
- Wrap with tying tape using the same technique as the fork attachment — tight, stretched wraps.
- Repeat on the other side.
Make sure the pouch is centred between the two bands. An off-centre pouch pulls the ammo to one side during release, causing consistent misses in the same direction.
Your slingshot is built. Time to test it.
- Inspect everything first — Check that all tape wraps are tight and secure. Give each band a gentle tug to make sure nothing slips.
- Start with light draws — Draw to about 50% and release. This lets the bands settle into their attachments.
- Check alignment — Both bands should stretch evenly. If one side is tighter, adjust the band length by re-tying.
- Gradually increase draw — Work up to full draw over 10–15 shots to get a feel for the power and trajectory.
Always shoot at a safe target with a proper backstop. Never shoot at anything you don't intend to hit.
Tips for Better Results
Building from scratch is a great project — but if you'd rather skip straight to shooting, our ready-made slingshots come with professional bands, a precision-cut frame, and everything you need out of the box.
