Thanx.I'm not referring to elastic as in rubber bands. I'm referring to woven, stretchable elastic fabric. The stuff that is used for wrist bands, head bands and belts. I have used that for similar purposes without fail. Go talk to a local fabric supplier or search online for elastic fabric. It is available for many applications. It is tough, durable, and long-lasting.
Most rubber naturally get`s crumbly over time.Bungees last a long time but getting the fit is the problem.Wire "might" twist & break but again it`s not a toy.Some people don`t know better & will play with the arms anyway.That was the first thing my daughter did to it when I showed it to her.I had to ask her not to play with the arms.There are many types of elastic fabric. The kind that holds up your socks and underwear is a very weak variety. There is no reason why quality elastic fabric cords cannot last indefinitely, if properly installed and not subjected to harsh chemicals, extreme heat, etc. These conditions would probably ruin your model before they would destroy the elastic cords inside.
I never use rubber bands for anything that has to be sealed, or that I otherwise want to last. Rubber will always deteriorate over time. Good quality elastic fabric bands or cords should last as long as the model.
Be cautious if using springs, as they may slowly lose their tension (i.e. stretch) over time if they are bearing a constant load.
Only my third post (I'm a lurker).Elastic rots too quickly.Then your stuck with the task of removing the head again.
You must have pretty loose arms on yours because in order to get a snug fit you need a band that`s quite abit shorter then the width of the kit.It`s a major pain trying to fish it across besides I`m looking for something permanent not something I want to change every 5 yrs.:freak:Only my third post (I'm a lurker).
I don't understand the problem. Why would you remove the head to replace the elastic holding the arms?
After everything was painted, I put the arms on last. That's why a stretchy cord is used. You tie it to one arm, fish it out the other side and loop it to the other arm. The tension pulls the arms against the body. It works perfectly. If it ever fails, grab an elastic band and do it again. Even if the elastic rots after a while, it's a quick fix. It takes a couple of minutes and certainly doesn't require removing the head. It's simple and effective.
Is this really difficult?
