6 Tips for the Perfect Cut
Using a circular saw can be a little bit tricky compared to other tools like jigsaws or electric drills. A poorly operated circular saw will not only fail to achieve the clean cut you are aspiring to, but more importantly, can result into injury. Today, we’ll give you some tips on how to make the perfect cut using your own saw, and keep safe.
Before you do anything, run a quick check on your saw. Be sure the lower blade guard retracts smoothly and snaps when released. Check the blade for cracks and chips. Replace the blade if you find any damage. Check the battery if you’re using a cordless saw. If not, check the cord for any kind of damage before using it.
Perform a blade check
The performance and the cut quality depends highly on the blade. Never cut with a rusty, dull and damaged blade. Use the right blade for every material being cut. Consider using a thin kerf carbide tipped combination which can be used for crosscuts and rip cuts in solid wood and plywood.
There are hard and fast rules regarding which direction you should cut in, but whenever possible position the saw with its motor facing towards the larger section of board that isn’t falling away when you make the cut. In this manner, the saw’s base plate will be fully supported during the cutting process.
To make accurate crosscuts, guide the saw with a square layout. Hold the saw in place with the blade on the cut line. Slide the square against the saw’s base plate and press it tightly against the edge board. Now simply guide the saw along the square to produce a square cut.
When cutting sheets of plywood or paneling, ensure there is sufficient support to eliminate kickbacks when the blade gets pinched during the process. What you can do is place two 2x4’s underneath the sheet you are cutting, spacing one 2x4 close to each side of the cut line. When you make the cut, both halves will be supported by the 2x4.
Avoiding wood splintering
To avoid wood splintering, place the board or panel with the best surface facing down. This way, the splintering will happen on the backside. When trimming doors down to the right size, place the best side down. Then score along the edge of the cut line with a utility knife. And then make the cut. The wood fibres will eventually break off cleanly at the score line, leaving a smooth cut.
