I am going to build a compost sifter. It will be a shallow box
three feet long and two feet wide with wooden sides and a hardware
cloth bottom. I bought two five foot long, five inch wide, redwood
fence boards for the sides. I have a circular saw.

Should I miter the ends of the sides, or would a butt joint be
adequate? Should I use steel corner reinforcements? Should I put
the hardware cloth on the outside of the frame or on the inside?

Thank you in advance for all replies.
