The T joint is the simplest joint to make, where a side meets a cross piece. The cross
piece must be cut exactly to form a perfect flat, square base. Place the piece onto the
flat piece and nail together. Try to nail from the surface of the flat piece into the
cross piece. For extra strength, slant the nails to form a dovetail.
If you have to nail the cross piece down onto the flat piece, more care is needed when hammering to
avoid moving the cross piece out of line. Hammer from both sides of the cross piece into
the flat piece to avoid the structure slipping.
