Hi,
I am trying to butt a piece of Crown molding up against the wall at a
135 degree (inside) corner.

I am using the 'lay the molding flat and look up the tables' approach
to figure out where to cut. The moulding is rather large so I can't
stand it up and just slice 135 degrees.

Any suggestions as to what miter/bevel angles will give me a 135 degree
angle?
Is is even possible?

Thanks
