Hi

I cut two pieces of nosing at 45, but they don't line up when I join them together to make a 90 degree angle. I'm using a miter saw to cut the angles. The blade cannot be angled. What I'm I doing wrong?

Thanks
Marko

Are you cutting the nosing with the face down? This will help keep the pieces aligned correctly. Is the blade still sharp? You can tweek the angle by keeping the nosing against the fence near the blade and move the nosing away from the fence at the end of the table to get a fine adjustment. You will only be able to do this after the nosing is cut to approximate length.

I'm cutting it face up and the groove against the fence as I thought it will prevent splintering the other side. The blade is quite old. Why isn't as simple as setting the angle to 45 degrees? Is there any website or video explaining this to a rookie.

A sharp blade is necessary, too. The hard grain of Oak can affect how a blade cuts, especially when cutting angles.
