Hi
Some soldering questions:
1. I bought a decent iron, but the tip is still losing heat. Even on full power (something like 30w) I'm having difficulty just melting solder. It seems to get blackened pretty quickly, but I don't see how this can be avoided. I have a battery powered iron with a larger tip - this is much better, but holding the button in and waiting for it to heat makes it impractical.
Any tips?
2. How do I solder wires to the connection 'posts' of pots/switches? They don't seem to hold any solder, so I can't tin them. The wire just dangles off and causes bad connections. I'm sure I shouldn't be relying on my glue gun so much...
3. Those little bits which stick out of pots are annoying! I assume they are to help locate the pot and stop it from turning when the knob is rotated. I'm afraid I lost patience and used the iron to melt a hold for them in the side of the toy, but I'm sure there is a better way... Any thoughts?
Many thanks
