I find that on some aircraft builds I need to airbrush all sides in one sitting. Usually there is a place on the aircraft I can insert a rod or clamp or something to securely handle the model during painting without touching the actual model.
On some builds I an unable to find a good way to create a temporary handle. For these I place the entire model into a clamp. Using a clamp with rubber ends I can secure the model with just enough pressure that the model will hold with friction.
I have clamped it end to end or wing tip to wing tip, whichever works and secures the model for handling. As I airbrush I gingerly move or tip the clamped model around to get to all sides. I have even placed it on a lazy Susan.
I often cut up coathangers to get wire for this. In addition to putting it in propshaft or jet nozzle holes, I have bent it into u-shapes to put it in landing gear holes (I put in landing gear after painting).
I agree it’s a novel idea but… (there’s always going to be a but - LOL!!) what happens if for some reason the kit suddenly slips off and goes crashing on the floor while you’re airbushing? Murphy’s Law is always happens but hey, you never know what can happen.
I agree there is a risk it can slip. If memory serves I have painted 7 aircraft like this and so far none of them have slipped. The rubber ends on the clamp are key as they slightly depress from the pressure as the clamp is tightened.
As i reposition the model to spray a different side, I will put the airbrush down and using both hands, I gingerly reposition the clamped model. I will also hold the clamped model standing tall, allowing to slowly twist the clamp in place as I spray.
