In the past, I have created several blogs about making kerfs, using both hand and machine tools. However, there are so many blogs that I no longer know where they are located. I definitely want to add some new articles to my How to page soon, but at the moment I am busy with my new laser.
Speaking of lasers, you should realize that if you use them to make kerfs, they will turn black. Although that is an accent, you have to want that.
I'll check my LJ history in a moment to see if I can find something for you.
I do remember, however, that I made most of the kerfs (the straight ones) for the SUV on the saw machine. I have a saw blade of 150x1.5 x arbor hole. The bevel groove was made with a V gauge.
But you can get a lot of enjoyment out of a laser. Just think of the inscriptions you can create on your models. A laser is also suitable for tires with text, and ...... also for making templates if you buy one above effective 20/30 Watt.
