Both gears modified, one ready to weld onto the thread and the second gear has been machined out to fit onto the servo horn.

Well all is complete! the head tilt mech is finished and in the machine. Its extremely tightly packed. Need to find a new home for the scorpion esc now. Head is almost full retracted here.

And here is the head fully forward, you can see most of the head tilting mech here.

Next job is the arms mech and creating the single tooth for the head. Then its armour up time and away we go!

looks brilliant, is the tilt mechanism like an actuator?

**PJ-27** · 21st May 2012, 20:56

Oh I see what you're doing! You've a gear on the servo head, which engages a gear on the threaded rod. The thread on the rod then pulls and pushes a nut which is attached to the head?

Does the servo have enough travel?

**james...venom** · 21st May 2012, 21:19

Yes your right PJ, I've modified the servo so it continuously rotates. It has 14kg or torque and rotates once in 1.08 seconds so it's slow but that means we can keep it very controlled.
