Hardwood nails always bend and deform? Whether it is mahogany, oak or teak, novices can also succeed once they master the following professional skills!
Tip 1: Choose the right nail material and shape.
Cement steel nail: the hardness is as high as HRC50+, and the penetration is three times that of ordinary nails.
Spiral twist nail: rotating structure disperses pressure and reduces bending probability.
Galvanized self-tapping nails: with pre-drilled holes, the bending risk can be reduced by 80%.
Tip 2: the golden rule of pre-drilling
Pre-drilling pilot holes for hardwood surfaces with electric drills;
Aperture = 70% of nail diameter
Hole depth = 1/3 of nail length
Emergency plan: use awl to carve positioning dent instead of drilling.
Tip 3: Third-order hammering method
Tap positioning: the first three hammers are kept vertical, and the force is controlled at 30%.
Uniform force application: the middle 5 hammers gradually increase the strength to 80%.
Finishing correction: the last two hammers quickly hit the top vertically.
Tip 4: 45 oblique nail bending prevention
By tilting the penetration angle:
Resistance of dispersed wood fiber
Improve nail grasping force by 30%
Reduce bending probability
Tip 5: Lubricant black technology
Apply to the tip of a nail:
Beeswax: reduce friction resistance by 50%
Soap liquid: an urgent alternative
WD-40 antirust agent: It has both lubricating and antirust functions.
Frequently asked questions
Q: How to remedy the bent nail?
A: Hold the bending part in a vise, and continue to use it after reverse tapping for correction.
Q: What should I do if the nail comes loose after driving?
A: inject wood glue or insert glue-soaked toothpicks for reinforcement.
Master these five skills, and the success rate of hardwood nailing will increase by 90%! Be sure to wear goggles and non-slip gloves when operating.
