Cutting Tips
All machinery used to machine wood will become more efficient when used properly. When it comes to making clean, glass like cuts, a sharp chopsaw blade is in order. As seen in the illustration above, with a sharp cut, there no sanding required. Seams are truly seamless. Three things contribute to a seamless joint:
Back bracing the cornice for a tight fit (as describe earlier)
Cut at a 30-degree angle to increase the surface area, 45 degrees would be too sharp a corner and flake off leaving a gagged edge.
A sharp blade, our installers sharpen there chopsaw blades once or twice week
With the above three principles employed, simply re-premiering the joint is all that is required.
Sharpening your tools produces a cut that is:
Not torn out
Producing knife marks that are within industry specification
Producing edges that are not burnt or burnished
A sharp tool provide for a safer worksite and helps to produce a higher quality product. A sharp tool is common thread that joins every tool used in the woodshop. The best finish is produced with a sharp tool and worst finish is produced using dull tools. Sharp tooling is also much safer. Sharp saws will offer less resistance to operator effort, making it easier to process parts for longer periods of time.
By exploring these concepts further, one only needs to operate a dull chop saw vs. one with a sharp saw to illustrate this point. Assuming the correct sawblade is utilized for both, a dull saw will make smoke, tear edges and corners, cause inaccurate dimensioning, and slow down the feed rate requiring more pressure to make the final cut. A sharp tool is less prone to kickbacks due to the easy cutting and the reduced back pressure created by the cutting edge.
The use of woodworking machinery and its tooling comes with many inherent risks. Every woodworker should always familiarize themselves with company safety policies. There is no way any course can prevent accidents. Only your skills as an operator and the use of safe practices can prevent accidents. Only work on a safe machine, utilize all guards and personal protective equipment, and do not bypass and interlocks engineered for your protection.
