• Lay out the arch pieces symetrically, matching the numbers at the end of each arch piece.

• Insert 5-1/2" bolt through the 2 end pieces at the arch foot and slide the cross-beam under the short piece. Push the cross-beam past the bolt hole above it. Separate the arches so the X on the cross-beam is just outside the arches. Lift the long piece and

• add the next piece by putting a 4-1/2" bolt through the crossing and mate the lap joint over the cross-beam.

• Tap the cross-beam to center under the peak so that the lap joint fits. Everything is shaky while you're adding pieces. Try to have someone hold the arch to keep it from tipping while you're completing the arch assembly.

• Lift the new ends on something like a saw horse.

• add the next piece by putting a 4-1/2" bolt through the crossing and mate the lap joint over the cross-beam.

• Mate the lap joint over the cross-beam and move the saw horse. With a helper, it's not too difficult to dispense with the saw horse

• Slide a cross-beam under the short ends and lift the long ends on the saw horse.

• add the longer of the two end pieces by putting a 4-1/2" bolt through the crossing and mate the lap joint over the cross-beam. Add the short end piece with a 5-1/2" bolt at the arch foot.

• Whack the arches into line so they line up with the marks on the cross-beams and stand vertical. •

• All joists point in the same direction except at one end, where the end ramp and joist are fastened to the same arch peak with one bolt. •
