I continued the build today with some fine PE work in the fighting compartment, mainly ammo stores and a FuG radio cage. Very fine bits indeed, the smallest was 2 by 1 mm plastic and even smaller PE nuts.
I learned the technique of soldering PE today using flux. This considerably increases the stiffness of the finished PE result and avoids the issues wit CA glue such as finger gluing and nasty fingerprints on the finished model.
Attached is a picture of the setup: Soldering iron, a wooden base, tweezers, hobby knife and cocktail sticks. I first bent the PE, in this case in box form. To do that, I build my own 5$ PE bending tool first. After bending, you use the cocktail pic to apply soldering flux to the joint, i.e. where you want the solder to be. Then you melt some solder on the tip of the soldering iron and briefly bring the iron in contact with the joint covered in flux.
A wonder of nature, but the acid nature of the flux (careful, it’s poisonous) combined with its ability to lower surface tension of the molten metal results in a fine layer of solder in the joint. I tried a closeup to make it clear. Finishing consists in some sanding but if you are careful not to apply too much solder to the tip, it is minimal.
I made a little drawing below to illustrate the technique, check it out!
Happy to share this here and hope you learned with me today 🙂
