What’s the Best Straight Edge for Cutting Plywood at a 45-Degree Angle?
Asked by CraftyNinja97
I'm looking for recommendations on the best straight edge to use with a skill saw for cutting plywood at a 45-degree angle. Ideally, I need something that can handle 8-foot sheets, but if it can only manage 4 feet, that would work too. I've been considering the Kreg Accu-Cut but have seen some reviews that suggest it might slip. Any suggestions?

I actually use a 6-foot aluminum level from Harbor Freight along with some clamps. It’s straight and doesn’t flex like some other materials might. Just make sure to keep it steady as you cut!

Some people seem to confuse straight edges with track saws! But seriously, any good straight edge will do the trick. I use extruded aluminum, but just be careful with wood since it can warp a bit and mess up your cuts unless it’s perfectly straight!

Honestly, you can get away with just using a nice straight 2x4 and clamping it down. It doesn’t have to be fancy as long as you secure it well before cutting!
