General tips for framing hammer use:
  • 20oz is a good weight for carpentry and framing. Those with large hands can use 24oz. 16oz and 7oz are for cabinetry.

  • Make sure the crown is rounded and not flat. The crown strikes the nail. A flat crown is more likely to bend nails.

  • Keep the crown clean. If dirty, use sandpaper to expose the bare steel.

  • Hold the handle about 35-40mm from the bottom end, the opposite end to the crown. Don't choke the grip unless just starting a nail.

  • When the crown strikes the nail, the nail head, crown, handle and knuckles should all be on lines parallel to each other.

  • Use gravity with the weight of the hammer head to drive nails.

  • Avoid splitting timber by predrilling to 80% the diameter of the nail. Also, don't drive a nail within about 16mm of the timber edge, an inch is better. Blunting or oiling the nail tip can also help.

Tips for learning to skew-nail 75mm / 3" nails:
- Predrilling 80% the diameter of the nail will help, and will be essential in seasoned hardwood to avoid splitting the timber. The hole shouldn't go more than 10mm into the second timber to be joined. Standard galvanised framing nails are 3.05mm to 3.15mm in diameter.
- Use clamps on the opposite side of the nail to be driven. Later you can just put your boot there.
- Put a few drops of machine oil onto the nail.
- Gently tap the nail into the predrilled hole. Increase the strength slowly.
- Standing over the nail, hitting down towards the boot on the opposite side of the timber, will improve aim.
- Do about twenty or so nails before trying to drive the nails almost flush to the surface. As your aim improves, you can return to the earlier nails and drive them home without leaving crown dents.   kellyjones00 (593)
