Sticking doors

[Cadmus Tyro]

Hey Frater,

 

Ive tried looking online for the answer to this one but nothing comes up. 
 

How do you avoid moving part sticking together and causing paint damage? I’ve tried various things over the years, using rattle can primer, thin AB layers, protecting it with rattlecan varnish, leaving it to dry for prolonged periods. Nothing seems to work.

 

The issue occurs on parts that naturally rest together, drop pod doors, Minotaur earth shaker rest. So there’s nothing you can do to reduce the risk “mechanically” by sanding the part down.

 

Any suggestions?

I have two immediate ideas.

1- Sand the doors until they dont stick any more, then sand a little more to allow room for the paint, and for them to still not stick. THEN apply additional coats of varnish around the contact points until they meet and hold.

2- Magnetise, do the sanding part and then magnetise them closed.

Thanks for the reply.
 

The actual mechanism for the door opening is not the issue. It’s more where the drop pod door rests against the upright fin of the pod:

still WIP, apologies for the rough drawing! 

The pieces are meant to rest together in the closed position. So additional sanding won’t work.

Outta left field here, but what about that clear tape used on car door sills?

 

It is a bit thick, though, but if you put it on the doors, not the frame, it might not matter too much?

When you say sticking together, that sounds a bit odd, as once the paint is 100% dry, the bits shouldn't stick, yeah they will rub, but not stick.  Maybe try some matt varnish from a pot, add a few well thinned coats and let it dry for a few days.

I was thinking along similar lines, maybe just a shaped strip of plain old clear sticky tape on just one side would get it done.

Magnetise the doors so that magnets are holding the doors closed?

 

I suspect that most paint damage would be done by the friction of the doors rubbing against the doorframe - magnets should hold the doors in place enough to stop any small movements.

 

I’d also consider a good few layers of varnish against surfaces that contact each other.
