This Battle Droid build drives me insane...i never stumbled upon so many mechanical issues during a prop build like this one.
...as you can see here i have already begun with the middle section / torso, which created so many problem´s that needed to be solved, for example, how can you work with something that does not have one single straight line, to create a point of reference to work from ? ...not to mention that you can not fix this piece in any position, to sand glue or do anything else with it... so you have to hold it in your hand the whole time.
There is one thing that disturb´s me really, the mechanical parts that holds the Head in place, and the joints that allows him to move the head in the Z and X axis,...they just could not work that way like they do in the Movies, ...cause the Head, if he turns around the Y axis is forced to follow the movement of the space that the mechanics allow him to rotate right or left, but he makes a tilt with his head by around 15 - 20 degree´s around the Y axis, and roll´s his head...but in the Star Wars movie, no Battle Droid ever does that, so there must be an error in my construction itself...
As a reference for his Neck angle i have use some blueprints of a 3 side view,...and after adjusting that thing 2 times, i finally cut the neck off from the torso, cause i was not happy with the result...and glued it back together into a slightly different angle then it was before, ...like i said, when you don´t have a straight angle or line that you can use as a reference point, ...then you have to assume or guess, which can lead into an very unsatisfied domino effect, if there is an error in any measurement before...and that happen a lot during this build
Those 3 point´s in the area where the neck meet´s the torso, are wooden sticks, which i often use to hold the foam part´s together during the water based construction glue cures, ...later on i will use some ultra light filler for a smooth transition between the neck and the torso.
At this stage i have mounted the whole thing on a 4 by 4 timber beam, ...and i sadly realized that it will be a huge challenge to get the finished Droid able to stand on his own feet, without any support beam, maybe i even have have to install some counter weight´s in his body or his legs, i will see later on if all that is necessary or not, hopefully not...
