Awesome, guys! One of the reason why I came here is because of the expertise of it's members.
I have another noobish question.
How do I hold the wires together when soldering? I typically use two people, each to hold one wire. However, that seems very dangerous! Perhaps there's a more effective/efficient method?
1. Prime the cable. The FRC stuff I was dealing with come with the jacket pre-stripped but the remainder of the jacket still on the loose end that you can pull off by hand. So just pull the off, flux and prime the cable. (ie: put some solder on the stripped part of the cable.) Aim the flame AWAY from the jacket point the flame towards the cut end of the cable as you prime.
2. Use a desk-vice grip to hold down the connector, clean, flux, heat it up, prime the darn thing.
3. Inspect both connector and cable to ensure it is properly primed. Crimp it in (or not). Crimping it as much as you can is a good thing. It will take a lot of abuse during competition.
4. Now apply solder generously.
5. Tape it down. Cover as much of the exposed as possible to avoid accidental shorts. You may know electronics, most of the others on the team don't. You want to avoid the slightest chance of accidents.
6. I like to apply a layer of heat shrink before the taping. But remember, it may need to be removed very quickly too. On the field repair is not uncommon.
The smart teams are those who would replace their battery whenever given a chance - if your team is like that, make sure the nuts are aligned properly for quick replacement. There was a false start that one time, just 20-25 seconds into the match. The smart team came out to
replace ALL their batteries before restart. 20-30 seconds is a quarter of the match time! You used up a lot of your battery's prime time. When you have to push the other guy out of the way, fresher battery wins. (The other guys are probably using the exact same motor you are using. So, strength is reduce to how much juice is in your SLA.)
EDIT: Have to add this: Make sure you practice a few time in wide open space. The common mistake is to move your hand (while the flame is still on) and pointed it at the wrong angle. If you have
more than one person around while soldering, they would be all huddled to watch what is going on, and perhaps try to learn something. As you remove the torch, naturally, it will sweep an arc of your arm's movement. The other people around could get burn easily.
Make sure you tell them to watch out for the torch as well .
