I am a relatively new ham, and have started getting into building kits and I keep wondering the answer to this question. You put some parts on the board (resisters, caps etc) through the holes, and then you go to solder them on the back, how should you make them stay put so they dont fall out a little and make the leads a little long etc.. I have been using a little electrical tape to hold them when I turn the board over. I tried bending the leads on the components, but even that does not often keep them from slipping out a little bit and making the components stick up a little off the board etc.. Am I doing it wrong? Am I missing something obvious? I am just wondering how the elmers do it.
