How to Operate a Circular Sawmill
A circular sawmill comes in handy for various home projects. It is one of the 3 types of portable sawmills available for timber jobs. The other 2 types are the chainsaw mill and the band sawmill. The circular sawmill has a thick round blade whose circumference is punctuated with efficient teeth at regular intervals. It cuts through timber at very high speed. A variety of blades can be used on your sawmill. Each blade is designed to perform a specific task. Proper use of the tool is vital for personal safety. Below is a guide that shows you how to use the tool.
Step 1 – Support the Work Piece
It is important that whatever you intend to cut is supported from underneath. This helps to ensure that the blade doesn’t cut into anything underneath the work piece. Get the material you intend to cut and place it in a sawhorse. Clamp down the work piece so that it is securely in place.
Step 2 – Mark the Lumber
Use your pencil, measuring tape, scaled rule and T-square to mark the cut line on the work piece.
Step 3 – Choose the Blade
Select the right blade for the job at hand. A ripping blade allows you to cut in the direction of the wood grain. A crosscut blade allows you to cut against the grain. Inspect the blade to make sure that all the teeth are intact and it has no damages. The blade must also be very sharp.
Step 4 – Set the Saw
It is important that you only use a portion of the blade that will get the job done. If you’re to cut through lumber of 50 millimeters, set the blade at 55 or 60 millimeters. This helps to reduce the risk of kickback.
Step 5 – Align Blade on the Cutting Line
Position the front of the saw onto the work piece. Let the outer guide notch fall onto the cutting line. Turn on the machine and begin to cut along the line. Keep your eye on the guide notch. As you proceed, be sure to check that the saw base is on a level position on the work piece.
Step 6 – Cutting Through
Use sufficient force to drive the saw into the work piece. If your blade is sufficiently sharp, it’ll cut through. If you feel the blade slow down or begin to bind, do not force a cut even if you’re close to the end. Turn off the machine and allow the blade to stop completely. Adjust the work piece or supports to create balance after which you may cut once more.
Step 7 – On Completion
Turn off the machine and be sure the blade doesn’t spin anymore. You can then set down the saw.
- Do not cut with the circular sawmill if you notice the teeth are bent or the blade is dull. This increases the risk of kickback which can cause grave injuries.
- Be sure to wear safety goggles, hearing protection and a dust mask or respirator. A lot of dust is generated during the work.
