Cutting a trim board perfectly is very important especially if you want your home improvement projects to go perfectly. It is necessary to learn how to mark and cut a trim board accurately, according to the measurements that you have taken in order to make your work easier.

If you cut miters even the slightest bit shorter than required, it can make your project look extremely imperfect and shabby. If you do not want to waste your trim board, it is best to employ a technique that can help you speed up your work and can also help prevent wastage of materials.

Step 1 – Preparing a Cutting Base

Mount a support board to your miter saw. This will help you get a better cut. Such a support board can be made from scrap wood pieces by screwing it to your saw, right at the back end of the fence. The base will help you extend the saw and also prevent the trim board from sliding away while performing the cut.

Step 2 – Preparing the Board

Tack your board neatly to the cutting base. You can place the end of the board in the exact position where you have to make the cut. This works well for both straight cuts and angled cuts. Once your board is tacked in place and is not moving, use your pencil to mark the lines where you will perform the cuts. Presuming you already have your measurements, measure the right proportions and use a V to mark the piece instead of a line. Line up all the cuts that you have to make on this board.

Step 3 – Marking

The marking of the board should be done very accurately, because almost all inaccuracies in projects come due to inaccurate markings. Marking a board with just a line will not allow it to be completely straight. Therefore, to avoid lining up the wrong end, a V mark is used instead. This shows you the exact place where you have to cut. You can repetitively line up the pieces to the board tacked to the cutting base.

Step 4 – Lining up V Points

When you have aligned the V mark with the end of the cutting base, you will get a straight cut. However, while you are aligning these, make sure that you are looking straight at board. When you are looking at these from the side, it may look a bit off, factoring in the parallax error. The V marks should be oriented in a manner that they are on the side of the cutting base so that there are minimum chances of error.

Step 5 – Making the Cut

Keep the piece firm when you are making the cut. Make sure that your hand is at least six inches from the blade of the saw. You can grip both the support board as well as the trim board so that they do not move. For additional safety, use a clamp.
