A2.7 At front side, attach 2 of the Hexagonal standoffs. Insert the 3x10mm. screw through

the 3-hole straight joiner and the leave hole of the short angled shaft base from step A2.5

to fix with the 30mm. Hexagonal standoffs.

A2.8 With the board still upside down, Insert the metal axel into the holes of the long

angled shaft in the hole positions of 2 and 6 as shown in the Figure A2-11. Place the Me-

dium track support wheels over the metal axel. Insert the hubs over the wheels so that

the wheels and the axels are connected tightly. Turn up the base. Insert the 3rd metal

axel into the holes of the short angled shaft. Place the Large support wheel over the axel.

Insert the hubs over the wheels so that the wheels and the axels are connected tightly.
