How about a soldering thread?


There's one thread with some good tips on soldering i.c.'s, but like many, I'd like to tackle the Homegrown cable kits. I suppose the instructions are good but I know from teaching hand cutting dovetails that there are things I do, things you don't hear about, that make the job easier and the joints more precise. Things like spending ten minutes turning a crosscut into a ripsaw, making chisels "scary sharp" and finding the inside and outside of boards.Let's hear from some veteran kit builders, please.

Kitch, a fellow woodworker! Audio is my second hobby and I have built a few kits in my time. There is no real magic in soldering. As in woodworking you have to have the right tool for the job. I have seen first time kit builders try to solder components on a circuit card with a 100 watt soldering gun and I just shake my head as they lift up the traces on the circuit card. I would classify the work you intend on doing as fairly delicate so I would recommend no more that a 20 to 30 watt soldering pencil. Use good quality solder, and in your case silver solder wouldn't hurt your interconnects. Make sure you keep the tip clean and well tinned at all times and apply only enough heat to do the job. Once the joint is soldered do not move it as this will create a cold solder joint. Not much more to it, just take your time and you will be fine. By the way, more power to you for cutting dovetails by hand but I much prefer the Leigh Dovetail Jig I got for Christmas and my router. Good luck.
Im no expert but you want to heat the work piece not the solder itself. This will help it flow better and make a better connection.
Be careful of those fumes.....I found out a while ago that I am allergic to them....I develop chemical bronchitis. So, I have hung up my soldering iron, except for very small jobs, and then with a suitable mask.
Dacostab- never new there could be a hazard from the fumes although plumbing solder has lead, yes? Anyway, many pro woodworkers and some hobbyists wear a powered mask made by Airlite, Airlite 3, about $250 which pushes overpressure air through the face shield. It's powered by a battery pak you wear like afanny pack and relatively comfortable. All the mail order tool dealers sell them. Go and solder more.
Dacostab, you need to get one of those little devices that soaks up the fumes(like the smokeless ashtrays). My old company(where we soldered all the time) had a bunch of them. It is not the lead that causes problems, but the flux. It is organic, and burns off. Yes, heat the work piece, use a good pencil and tip(tinned), and always use a heat sink for parts that can be damaged. Be especially careful of this with polystyrene capacitors. Silver solder is cheap, compared to the benefits it yields. I don't believe the new Silver Lace is available from HomeGrown Audio in kit form, as it is more complex(uses 8 conductors, vs. 3). Silver solder is supplied with the kits.
