Cut base planks so each has 45° ends.
Cut vertical lengths so each has 45° ends,
making 3 lengths ½" shorter.
Drill & screw (with 1½ inch screws) vertical
onto base (one long and one short),
use 3/16" guide hole for screws.
Then screw top together - voila, a triangle!
Do it three times.
Drill three 5/16" holes into adjacent triangles,
and bolt together with 2" bolts.
Mark and drill 5/16" holes into base for metal L shapes
to hold base as square,
and use 1½" bolts to hold base to L's - a pyramid!
Screw remaining 3 vertical lengths together to make door.
Position, adjust, and attach with hinges (to the rear vertical).
Add 2"x4" under base near rear (about 9" from rear)
with 4 screws.
Drill and attach lag bolts with wheels.
Cut 6" slot central to 2"x6" wood.
Drill ½" hole for axle.
Insert 6½" bolt, wheel and plus many washers.
Drill ½" hole in front for pivot.
Drill ½" hole in base at front.
Use 3½" bolt for pivot of front wheel,
with pivoting wood under base.
Use 2 extra washers to allow swivelling of caster.
Use two small screws to limit caster to not let front wheels
touch front plank of wood of base of pyramid.
Add two metal (upside down) T's to rear of bicycle.
Cut 2"x4" for rear strut.
Although may need to block up (raise) strut to match base height.
Remember to cut 45° at end of 2"x4" so it does not
overhang where mesh will be.
Drill two ½" through width of 2"x4" so
T-shape has two 4½" long 5/16" bolts across it.
Use the two 4" bolts to attach the rear wood to the base.
Add small 1"x2" wood with 1" hinge for support
of the rear strut when the bike is out (at night).
Add hook & eye to hold the support open, and velco to hold
it up (in the daytime).
Cut 2"x4" for front strut so the U-clamp will attach
around the front of the bicycle steering column and the wood will
be on the front of the bike.
The base of the 2"x4" is slightly angled forward
and tilted at the angle of the bicycle steering column.
This is fun to cut to get it just right!
Bolt to base with 3½" 5/16" bolt,
which needs a 1" recessed hole for the washer.
Drill holes for U-clamp into wood, and attach around bike.
Add another strut support, hinge, hook & eye, and velco.
Add slats to triangles for mesh support.
Cut mesh diagonally in two, and staple mesh to triangle.
Do that 4 times for each triangle face of the pyramid.
