Installing a Boyd's stock on your Savage Mark II can significantly enhance its ergonomics and aesthetics. However, improper tightening can lead to stripped screws, damaged wood, or even a compromised action. This guide provides crucial torque specifications and best practices for a successful and safe installation. Remember, always prioritize safety and accuracy when working with firearms.
Understanding Torque and its Importance
Torque, measured in inch-pounds (in-lb) or foot-pounds (ft-lb), represents the rotational force applied to a fastener. Applying excessive torque can easily damage the stock's wood or the action screws, while insufficient torque can lead to loose components and potential malfunction. Using the correct torque is critical for a secure and lasting installation.
Unfortunately, Boyd's themselves don't typically publish precise torque specifications for their stocks. This is because the ideal torque can vary based on several factors including:
- Stock Material: The type of wood (e.g., hardwood vs. laminate) affects its strength and resistance to over-tightening.
- Screw Material and Type: Different screw materials (steel, stainless steel) and types (Phillips, flathead) will behave differently under stress.
- Environmental Factors: Temperature and humidity can influence the wood's properties.
Recommended Torque Ranges and Best Practices
While a precise number isn't available directly from Boyd's, we can offer a safe and effective range based on experience with similar firearms and stock installations:
Action Screws: Aim for a torque range of 15-25 in-lb. Start at the lower end and gradually increase, feeling for resistance. Never force it. If you feel significant resistance before reaching 25 in-lb, stop immediately. You may have encountered a burr or imperfection in the screw hole.
Other Screws (e.g., pillars, recoil lug): These screws typically require less torque. A range of 8-15 in-lb is usually appropriate. Again, start low and gradually increase.
Tools Required:
- Torque Wrench: An essential tool for precise tightening. Choose a quality wrench with an adjustable setting, preferably in the 0-50 in-lb range. Calibration is vital; ensure your torque wrench is properly calibrated before use.
- Appropriate Screwdrivers: Ensure you have the correct size and type of screwdriver for your stock's screws. Damaged or ill-fitting screwdrivers can easily strip the screw heads.
- Threadlocker (Optional): A small amount of blue Loctite threadlocker can help prevent screws from loosening over time, particularly on high-vibration applications.
Step-by-step Installation (General Guideline):
- Preparation: Carefully examine the stock and action for any burrs or imperfections that might interfere with the installation.
- Assembly: Carefully align the action with the stock and insert the action screws.
- Tightening: Start with the lowest recommended torque setting and tighten the screws in a criss-cross pattern (opposite screws) to ensure even pressure distribution. Gradually increase the torque, checking frequently for resistance.
- Verification: Once tightened, check the action's alignment to ensure it's properly seated. If any adjustments are necessary, do so carefully and re-tighten according to the torque specification.
When to Seek Professional Help
If you're uncomfortable performing this task yourself or lack the necessary tools, it's best to seek assistance from a qualified gunsmith. Improper installation can compromise the firearm's safety and accuracy.
