RYANSTAR RACING Piston Ring Filer 80514 — Bench-Mount Grinder with Carbide Wheel for Plated Stainless

RYANSTAR RACING 80514 is a bench-mounted piston ring filer with a carbide grinding wheel designed to set precise ring end gaps and dress plated stainless-steel rings quickly and consistently.

This compact piston ring grinder is built for small engine builders, hobbyists and professional shops that need a reliable way to achieve accurate ring end clearances. It clamps securely to a workbench, accepts common piston ring sizes, and uses a carbide wheel to cut plated stainless steel without excessive heat or chatter. The result is controlled material removal and repeatable gaps that help rings seat properly during break-in.

How does the grinding wheel cut plated stainless-steel rings without damaging them?

The tool uses a carbide grinding wheel chosen for durability and aggressive cutting on hard finishes like chrome or nickel plating. Carbide maintains its edge under load, reducing the tendency to glaze and minimizing friction-generated heat that can alter the ring profile. Proper setup and light, steady passes keep the ring flat and maintain original dimensions.

• Carbide wheel optimized for plated surfaces
• Light, controllable material removal to avoid overgrinding
• Bench clamp minimizes vibration for clean cuts

What features improve accuracy and repeatability when setting ring end gaps?

The filer mounts to a bench and secures the ring for consistent contact with the grinding wheel, while the rigid aluminum body resists flex during operation. This stability reduces variation between passes and helps maintain square end faces. Use a feeler gauge and test-fit the ring in the piston during the process for best results.

• Bench-mount design for steady positioning
• Rigid aluminum body for long-term dimensional stability
• Easy-to-adjust work angle for repeatable cuts

Which rings and engines is the 80514 compatible with, and what should I check before buying?

The filer handles most standard piston ring sizes used in automotive and small-engine rebuilds, including plated stainless-steel rings, cast iron rings and many aftermarket designs. Before ordering, compare the tool’s maximum ring diameter and clamp capacity with your rings, and confirm the replacement number 80514 matches your supplier reference. If in doubt, measure the ring outside diameter and thickness against the tool’s published capacity.

• Works on plated stainless, cast iron, and common ring profiles
• Check maximum ring diameter and clamp opening before purchase
• Replacement number: 80514 for parts reference

How do I use the piston ring filer safely and get a consistent gap?

Secure the filer to a solid bench, clamp the ring squarely, and make light, even passes against the carbide wheel while rotating the ring between passes. Frequently test the ring in the piston to measure the gap with feeler gauges; small passes avoid removing too much metal. Wear eye and hand protection and follow shop safety practices to prevent injury from sparks or broken stones.

• Mount the unit firmly to a stable work surface
• Make small passes, checking fit in the piston often
• Use PPE: eye protection, gloves and dust control

Who is this for? The RYANSTAR RACING 80514 piston ring filer is aimed at do-it-yourself engine builders, small engine mechanics, and performance shops that need a durable, bench-mounted grinder to set precise ring gaps on plated or cast rings. It’s useful for routine overhaul work, custom bore builds, and anyone wanting a cost-effective way to control ring end clearance without outsourcing the job.
