What Is Shimstock?
Shimstock is ultra-thin foil – typically metal – used to create custom shims by cutting or stacking to exact thicknesses. Thicknesses go as low as 0.0127 mm (0.0005″), making it ideal for precise alignment tasks.
Why You Need Shimstock
- Precise Gap Filling: Correct minute misalignments in fixtures, tooling, or machine assemblies.
- Calibration & Setup: Essential for alignments in pumps, valves, bearings, robotics.
- Custom Shim Creation: Create shim rings, U‑shaped shims, or flat pads with simple shears, punches, or laser cutters.
Common Shimstock Materials
- Carbon & Stainless Steel: Durable, corrosion-resistant – used in machinery, valves, marine environments.
- Brass, Bronze, Copper on request: Soft, conductive – ideal for electrical or delicate mechanical applications.
How to Use Shimstock in Your Workshop
1. Measure gap using feeler gauges.
2. Select material & thickness (e.g., stainless for corrosion, brass for ease-of-use).
3. Cut or stamp shim – use scissors for simple cuts or a punch/die for precision holes.
4. Install the shim, add layers if needed for required thickness.
5. Check fit, re-measure, and secure components.
Pro Tips & Machinist Insights
– Cutting edge: Sharp scissors or snap-off shears work great; silversmith shears again create cleaner curves.
– Punched holes: Use dowels, punches, or laser cutters to make precise holes.
– Stacking for precision: Bond laminated shimstock for thicker, layered shims.
