Jesper enjoys SCUBA diving, mountain biking, and especially photography, which he practices in his free time. He is currently a Project Manager at Millworks By Design, a finish carpentry company located in Agoura Hills, CA. ![]() More recently, he has focused on high-end finish carpentry.

He grew up in family homes in both Sweden and Denmark until the age of 18, when he moved to Los Angeles, CA. Jesper Cook was born in Stockholm, Sweden in 1977. In fact, some manufacturers include protractor angles on power miter saws: The easiest way to solve this whole problem is to use a Sharpie to mark your miter saw gauge with protractor numbers. But when you set your saw at 43 degrees and cut the piece, the miter is NOWHERE near close! That’s because 43 degrees on a standard power miter saw gauge is really 47 degrees. You first bisect the angle and determine that the miter should be 43 degrees. ![]() Miter saw gauges like this one (see photo, right) were easy for finish carpenters to use, and didn’t cause another problem: Let’s say you’re installing base molding at a corner that measures 86 degrees. Back before framers used miter saws, finish carpenters could use a protractor to read corner angles without any confusion. Miter saws didn’t always come with miter saw gauges that were set 90 degrees off from protractors. You can’t cut that miter on a miter saw without an acute angle jig. You can use a free service like imbgg to upload your image and paste the link into the URL box.A 22 1/2 degrees angle is an ACUTE angle. Only image files are supported at this time.
