10. Next, bend the Lexan sheet along the dotted lines. Start with the 15
degree bend in the middle, then do the 90 degree bend along the back.
11. Finish with the two 90 degree bends along the right and left sides.
After completing this, do a test fit to make sure the Lexan sheet fits over
the motor mounts.
12. After test fitting (and possibly tweaking), we will now drill holes in the
Garolite sheet for the mini hinges. Place the Lexan sheet on top of the robot
and use a Sharpie to trace the four hole positions. Then, use the punch and
drill method to drill the holes in the Garolite sheet.
13. Now, peel the backing off the Lexan to reveal the translucent sheet. You
should be able to see the tapped holes through it. Mark four of them with
a Sharpie and use the punch and drill method to drill them out. Next, we’ll
move on to the weapon.
Usually at this point in the frame
construction, I decide where the
charging hole will be. You should
try and hide it as much as possible.
Now, let’s build the clamping arm.
1. First, attach the Lexan arm to the servo
saver. Start by drilling out two of the
holes on the servo saver to 1/8". Place the
servo saver on the end of the arm and
trace the two holes with a black Sharpie
onto the Lexan arm.
2. Drill out the arm with the punch and
drill method. Use 4-40 screws and nuts to
attach the two pieces together.
