Does anyone know how to cut a 45 degree angle on a piece of 1/2" MDF? I'm trying to build a box, but the guys down at Sears don't seem to know anything or want to really help. I'm looking to make the edges connect together flush. I don't want to just make a straight cut and just screw that into the other piece of the enclosure. Looks totally unprofessional. So when the two 45 degree angle sides are put together, they form a perfect 90 degree edge. I hope and pretty sure what everyone knows what I mean. Also I'm not looking to pickup some huge and expensive tool just to make a speaker box. I have a dremel and was wondering if anyone knows how to do it on that. Or on something that isn't very expensive.
