That's fine I'm not looking for an argument, although a good healthy discussion is good for the hobby. I just don't want people to read that article and think that they have to get a half a dozen magnets, a steel plate and and RSU to be able to put an etched kit together because nothing could be further from the truth.
There are plenty of other things that can be used to hold things square, I use a mixture of a small 2 1/2" steel square and a few blocks of hardwood depending on what the situation requires. They all work fine for me, obviously other people have other solutions which work fine for them.
The "pumping of a lot of amps into a tiny spot" is another thing I have misgivings about. When I had an RSU it was supplied with a pencil tip, unfortunately this tended distort the brass due to the very localised heating. Yes you want plenty of heat into the joint quickly, but when it is very localised it can cause more problems with distortion. Also pump up the amps too much and you may get localised "de-zincification", brass being a copper-zinc alloy, localised high heat can leach out the zinc in the brass resulting in spot points where the brass weakens and appears porous. I filed the tip on my RSU to a chisel point to try and avoid the localised hot spots and get the heat distribution a bit more even. Still couldn't get on with it, all the wires were too much of a faff etc. so I sold it and went to an ERSA Solder station which I'm happy with. All credit to those that get on with an RSU, but to claim, as Raymond does, that "it is a technological improvement on a soldering iron" is in my opinion a rather pretentious statement to make.
