A step-by-step guide to installing Coyote/OD Green G10 scales on your Disaster Jr, including hardware checks and fit tips for a secure, comfortable grip.
Quick answer
Install your Coyote/OD Green G10 scales by first confirming your Disaster Jr is a 2020 or later model, then swapping the scales with the included titanium Allen bolts and checking for a flush fit before tightening.
Why the Iron Grip texture changes your install approach
The Iron Grip texture on these G10 scales adds traction, but it also means you should avoid over-tightening the titanium Allen bolts. Over-tightening can compress the G10 unevenly and reduce the texture's effectiveness. Instead, tighten in a cross pattern until snug, then check for any movement.
Also, because G10 is rigid, make sure the blade is centered before final tightening. A slight offset can cause the blade to rub against the scale.
When to consider a different scale material
If you prefer a softer, more absorbent grip, Canvas Micarta might suit you better. G10 excels in wet or oily conditions because it doesn't absorb moisture, but it offers less vibration damping. These Coyote/OD Green G10 scales are ideal for users who want a consistent, hard-wearing surface with a secure hold.
Step-by-step installation
- Verify model compatibility: Check your Disaster Jr's production year (2020 or later). If unsure, contact Half Face Blades support before proceeding. A quick serial number check can save you from ordering incompatible scales.
- Gather tools and hardware: You'll need the correct Allen wrench size (typically 1/8" or 3/32"—confirm with your knife's original hardware), the new scales, and the included titanium bolts. Lay out all parts on a clean surface. Missing a bolt? Stop and contact the seller before stripping threads.
- Remove old scales: Unscrew the existing bolts in a diagonal pattern. If the scales stick, gently tap with a soft mallet—avoid prying with metal tools that can scratch the blade. Keep old bolts and scales in a bag for spares or resale.
- Test-fit new scales: Place the new G10 scales onto the tang without bolts. Check for any gaps or misalignment, especially around the blade pivot. The scales should sit flush. If the fit is tight, do not force—inspect for debris or burrs.
- Apply bolts and tighten: Insert titanium Allen bolts finger-tight first, then tighten in a cross pattern (top-left, bottom-right, etc.) until snug. Avoid over-tightening; the G10 can crack if excessive force is used. Use a torque wrench if available—aim for 10-15 in-lbs, but always follow manufacturer guidance.
- Check blade centering and action: Open and close the blade slowly. If it rubs, loosen bolts slightly and adjust the scale position. Once centered, re-tighten and test again. A blade that falls freely without side-to-side play indicates proper centering.
- Final inspection: Ensure all bolts are flush and no threads protrude. Wipe off any fingerprints or oil. Your Disaster Jr is now ready for use. Re-check bolt tightness after the first few uses as G10 can settle.
