How to remove thread-locking glue
Many of you purchase armature kits or buy stand-alone stop-motion joints to build your very own stop-motion armature that fits your character. Stop motion armature kits out there, including ours, come with a high strength Thread-locking glue such as Loctite 270. This type of glue is used to prevent loosening of the connection. But, what happens when the glue doesn’t sit right on the armature connection? Or How about if you want to reuse the components for a different character? Well, panic not. We’re about to tell you how to remove thread-locking glue from your stop-motion armature on this tutorial.
Why use thread-locker glue?
The good thing about using thread-locking glue is that it allows for disassembling of the connections as opposed to soldering which makes permanent connections. However, soldering is stronger and more durable. Threadlocker glue is a liquid that cures at room temperature to a hard solid thermoset plastic when applied to metal fasteners and in the absence of air. This means that the glue applied in your armature kit connections fills the gap between threaded bar (like Ball head screws / Threaded Lollies) and tapped parts or nuts. Then after 24 hours, this gap becomes filled with a solid plastic that prevents the loosening of the connection.
There are two ways to break the connection made with the threadlocker glue:
- Applying higher torque (i.e. applying higher force) than the breakaway torque of the glue or
- Heat the connection until the hardened plastic loses its properties.
If a high strength glue is provided it means it has a very high breakaway torque making the method of applying greater torque very difficult. Heating the connection to the point that the glue gets destroyed is very easy and it’s the method described in this tutorial.
Steps to remove High Strength Thread-locking glue by applying heat
First of all, please beware that heat can burn your fingers (obvious, I know, but still…), so please use appropriate gear to protect yourself. Also, this is to remove thread-locking glue from stainless steel and similar metals. Other materials may not be suitable for applying heat as a method of removing Thread-locking glue.
- Grab a cooking torch or similar.
- Apply heat to the glued metal component for around 10 seconds (the bigger the piece, the longer it will take to burn the glue).
- Once you see a small amount of smoke coming from the connection you can stop applying the heat.
That’s it. The connection is now loose. You just need to clean the parts and they will be ready for you to use it again.
