Step 5: Legs Assembly

Picture 1: leg1-4

Picture 2: connect leg2 and leg3 with screw

Picture 3: then connect to leg1

Picture 4: connect leg3 and leg4 with screw

Picture 5: repeat Picture 1-4 to assembly 1 more

Picture 6: connect leg2 and leg4 with screw

Picture 7: connect another leg2 and leg4 with screw

Repeat Picture 1-7 to assembly 6 pairs of legs.

Step 6: Install Servo

Picture 2: put the wire into the body hole

Picture 3: push servo into the body

Picture 4: screw up upper side

Picture 5: screw up with bottom

Step 7: Install Crankshaft and Legs

Picture 2: install pair of legs into axis1

Picture 3: install axis2

Picture 4: install next pair of legs into axis2

Picture 5: install next axis2

Picture 6: install last pair of legs into axis2

Picture 7: instal axis3

Step 8: Install Paperclip Axis

align the leg1 and let the paperclip axis pass through the body and all the leg1.

Step 9: Test Run

Use servo tester check all legs run smooth.

Step 10: Install Another Side

Repeat steps 6-9 for the the side.

Step 11: Connect 360 Servos

Screw up the T-Journal mount and body with 8 screws.
