A Beginner's Guide: How To Scratchbuild a Servo Arm
Ahoy-hoy, ladies and gentlemen. Apparently I'm back with another one of these.
As you may know, I am in the process of creating a Preheresy Iron Hands army using only GW components and scratchbuilding because I love Heresy-era stuff and FW prices are bonkers. So, this week's Beginner's Guide to Scratchbuilding is going to be of use to Iron hands players, as well as those of you who fancy yourselves Mechanicus Magi and Big Meks. I will be showing you what is literally one of the simplest scratchbuilds you can do: a Servo Arm. It takes under fifteen minutes to get the core piece built (although obviously, greebling will take longer) and once you've made a few, you can start to adapt the design for all sorts of things everything from bionic limbs to walker legs. I've used it when scratchbuilding some AdMech Castellax, so trust me when I say it's a versatile design.
The Tools You Will Need.
This week it's incredibly simple:
- Poly Cement.
- A length of square styrene rod, about 3mm x 3mm.
- A length of cylindrical styrene rod, about 5mm diameter.
- Other thicknesses of styrene rod for greebling and sundry details.
- A small piece of thick plasticard.
- Your craft knife.
- A Space Marine backpack (if you want to make it for a Techmarine). I've used one of the missile launcher ones I had going spare, but honestly any backpack will do.
How To Scratchbuild a Servo Arm
Cut one of the vents off your Marine backpack.
Cut three lengths of the square rod. They should be about 8mm or so long if they're going on a Marine.
Using the 'roll score crack' technique we learned during my Heavy Bolter tutorial, cut three lenths of cylindrical rod. They should be only slightly thicker than the width of the square rod.
Arrange your pieces I'm sure you can see how this is going to work already.
Next, carefully shave down on your cyclindrical pieces like so. USE BOTH HANDS! As always, the photo is to show you the position your blade should be in. I cut using both hands. Remember to always be cautious with what you cut away here it's better to cut a little and take away more than to cut away too much and have to start again. Less wasteful too.
Here's the kind of flat surface you want. You may have to use the 'blade sanding' technique we learned in the Heavy Bolter tutorial to get it flat and level.
Next, glue it in place:
