Trials obstacle building instructions...

SANDWICH BOARDS

Sandwich boards are probably the most versatile trials
unicycling obstacle and are also very easy to make. They are
light and portable, and in my opinion one of the most
important elements of a good trials course.

_Materials_ 20mm (or more) thick sheet of wood 35x70mm (or
similar) planks 50mm long screws 2 solid hinges Solid string
or thin rope Wood glue

_Building_Instructions_

1. Cut the sheet of wood into two identical bits that are
preferrably almost twice as wide as they are high. A
standard size is about 250x400.
2. Cut the planks to the same width as the sheets.
3. Place one plank on the long side of the sheet (70mm face
down), glue it into place, then add at least 5 screws
placed diagonally. Repeat for the other sheet and plank.
4. Lay these pieces down flat, side by side with the planks
together and facing up, and separate them about 5mm
(maybe less if you’re using a smaller hinge).
5. Place the hinges slightly in from the sides and mark
where each hole
is.
6. Screw the screws (usually provided with the hinge) in
loosely starting with the outer ones. Check the
alignment of the hinges and planks. Tighten each screw.
7. Drill two holes in each sheet in the two remaining bare
corners. Make the holes only slightly wider than the
string you have chosen.
8. Open the sandwich board to your desired angle (around 60
degrees) and feed the string through the holes. Tie
knots on the outer side of each hole making sure that
the strings are equal in length.
9. Cut off excess string and lightly melt the strings at
the cut and also at the knot to prevent it from
loosening.
10. Ride on your new sandwich board.

_Applications_
- Gapping between sandwich boards at various heights
and angles
- Supports for planks and balance beams
- A unicycle stand for running suicide mounts (see

PRACTICE RAILS

The handy thing about this type of practice rail is that
it’s very portable. It allows you to move it around and also
to change the length of the rail. This design uses the
narrow face of a 35x70mm plank as the riding surface. It's
not quite as challenging as a 2cm diameter round railing,
but it's narrow enough that the rider has to focus on
staying on top of the uni rather than moving the wheel side
to side underneath them...more of a moving stillstand.

This particular design is for a 5mx35mm rail that’s about
20cm above the ground. These dimensions can be easily
changed to suit your preferences.

_Materials_ 35x70mm (or similar) planks, one 5m long 60mm
long screws Wood glue

_Building_Instructions_

1. Cut the planks into the following pieces:
- 400mm pieces (4)
- 300mm pieces (6)
- 210mm pieces (10)
- 160mm pieces (3)
- 90mm pieces (2)
- 5000mm plank to ride along
2. Glue and screw together the pieces as in the diagram.
Shown is the end support. For the middle supports, use
the 160mm pieces in place of the 90mm pieces and have
them extending all the way down. Also, attach the two
300mm pieces to the sides of the middle supports (in
place of the 400mm pieces) so that they rest on the
ground and face perpendicular to the 5m rail (see final
assembly picture).
3. Slightly sand or plane away the sides of the 5m rail
where the supports sit if necessary.
4. Place the two end supports and three middle supports on
the ground in a line and fit the 5m rail in the slots.
5. Give it a test ride.

-Note: The rail should sit approximately 20mm above the top
of each support. This allows an uninterrupted ride along
the rail.-

_Applications_ This practice rail is perfect for improving
your rail riding technique. It is low to the ground so that
you can build confidence in your skill level and then move
on to higher rails if you choose. Once you can ride all the
way along, practise riding it slower and slower. This will
force you to keep your balance longer and develop your
still stands.
