Papa Posted June 11, 2010 Share Posted June 11, 2010 Most places will sell an 80watt iron for stained glass work. Mine cost $34 Cdn. They come with two large mass chisel tips, 3/8" and 1/4". The beauty of this is you have instant melting and the iron is on the work for a second or so. I don't burn insulation any more and the wires do not become over heated. I use the 1/4" for most jobs and the big one for battery work. I know this is sacrilege but I use acid flux on heavy battery wires before I tin them. This helps the solder flow throughout the wiring. I figure that the model will be long gone before any corrosion has a chance to set in. It reduces my frustration trying to get a good tinning before I join the pieces, that's my rationalization anyway. Jack.. Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted June 11, 2010 Share Posted June 11, 2010 No one has mentioned FLUX. There are times when this is useful, even with cored solder. IT helps the solder really flow. I use Bakers fluid but this should never be used for electrical work. There are other fluxes but I never got on with them so well. I have three irons, a 12 watt for soldering servo leads etc, a 24 watt for medium work and a 40 watt for piano wire. I also have a 75 Watt Henley Solon that is nearly 60 years old and still going strong. TIP: when connecting up servo leads make a groove in some scrap balsa the same size as the wire with a small screwdriver. Press the two ends to be joined into the groove and apply the solder, you will have a very neat joint that will accept the heat shrink tube easily.....You did slide the heat shrink on before you soldered, didn't you?

Papa Posted June 11, 2010 Share Posted June 11, 2010 Hi Peter, I live in Toronto and I bought it at a local Automotive / Hardware store. You should be able to buy similar in any DIY or a craft shop although the later maybe expensive. Jack. Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 11, 2010 Author Share Posted June 11, 2010 Weller do a range of irons from 15 Watt right up to 175 Watt.My 80 Watt jobby just blew its element a couple of weeks back, and I got a replacement HERE for around £18.Edited By Timbo - Administrator on 11/06/2010 11:42:31 Quote Link to comment Share on other sites More sharing options...
Gemma Jane Posted June 11, 2010 Share Posted June 11, 2010 All good stuff here. I was lucky enough to learn soldering from Dad when I was very little I never knew how useful it would be to me at the time! Very cheap soldering forceps or clamps can be bought for a few pennies and come in handy for a job that always seems to require a third hand. But my top tip is artery forceps. I always had the problem that when soldering battery connectors/ESCs/Motors that I had to put the heat shrink on the wire first. The heat would often transfer up the wire and shrink the stuff just enough to make life difficult before I was done working. I then found if I clamped an artery forcep between my intended joint and the the heat shrink it acted as a good heat sink and solved the problem. Because they are quite heavy they can also help to hold everything in position whilst the soldering is done. Once you have artery forceps you will find at least 10 million other uses for them when modelling so will never regret the purchase. Quote Link to comment Share on other sites More sharing options...
Tim Mackey Posted June 11, 2010 Author Share Posted June 11, 2010 And if you cant get artery forceps, flatten out the jaws of a small crocodile clip and use that.I also recommend a simple "jig"made from wooden clothes pegs and scrap of plywood or similar. These can be used to hold cables and plugs etc inline whilst soldering, and with a few small holes drilled, 2 and 4mm gold corolly style plugs and sockets etc can be inserted and held steady whilst working on them too. The pictures of my rather rough and well used version should show the idea Edited By Timbo - Administrator on 11/06/2010 13:43:06 Quote Link to comment Share on other sites More sharing options...
Alistair Taylor Posted June 11, 2010 Share Posted June 11, 2010 Hi all this isn't meant to be a commercial plug, but can I recommend the small handheld gas torches sold by a reputable high street electronics store (and others) that are fuelled with a simple gas cigarette lighter. These make very short work of soldering bullet connectors, and are capable of heating smaller jobs (e.g. silencers) to temperatures high enough for "cold" aluminium welding, using commercial welding rods available from all over the place. As the heat is delivered by flame, rather than physical contact, you don't end up chasing the job round the bench or the vice as the lightweight connector obligingly moves out of your way when you push the soldering iron against it.... These can also easily fit in a flight box with a twist of solder. AlistairT Quote Link to comment Share on other sites More sharing options...
Papa Posted June 11, 2010 Share Posted June 11, 2010 Hi Timbo, I have a similar soldering station but I used the mica element forms from an old toaster and it avoids burning the plywood. You can screw them to the plywood and solder directly on the mica. An old trick from old school plumbers is to keep a piece of heavy canvas such as denim and keep it saturated in one spot with flux paste. Use that spot to clean the tips of the soldering iron or to rub down a solder joint when using a torch. Jack. Quote Link to comment Share on other sites More sharing options...
Biggles' Elder Brother - Moderator Posted June 11, 2010 Share Posted June 11, 2010 Totally agree that lead-free solders can be difficult to use and in most conditions do not seem to produce as good a quality joint. But, don't despair! The restriction on the use of leaded solder only applies to industry - private individuals can still buy and use leaded solder perfectly legally. A good source for solder is C&L Finescale - a railway modellers supplier. See their website here full of a huge range of solders of different melting points and make-up including leaded (most of their solders are leaded because no one wants to buy unleaded solder!) and silver solder (good for structural soldering on undercarriages etc.) They also sell solder pastes - really handy sometimes - and a wide selection of fluxs, irons etc. etc. BEB Quote Link to comment Share on other sites More sharing options...
Barrie Dav 2 Posted June 12, 2010 Share Posted June 12, 2010 For some time I've used a copy of Timbo's soldering 'jig' and it is excellent for the job of holding the little bit and pieces to be soldered. Other pegs can be added to suit the task in hand. Well worth the small amount of time required to make it, Well done Timbo. Quote Link to comment Share on other sites More sharing options...

Chuck Plains Posted November 30, 2013 Share Posted November 30, 2013 A DIY mini soldering station. Made from ally scrap/offcuts. The underside is covered with a layer of duct tape to reduce slipping.

Shaunie Posted November 30, 2013 Share Posted November 30, 2013 CPC do a range of thermostatically controlled low voltage irons at reasonable prices. If your iron doesn't have a thermostat it isn't worth a "breach of the code of conduct" sorry . The iron needs enough power and sufficient stored thermal energy to raise the joint to soldering temperature promptly, this minimises the risk of damage to electronic components and reduces the time for oxidation of the surfaces before the flux becomes effective. I use a flux pen from RS components, I'll post the stock number in the week, it often helps when the surface may be a little bit difficult to make the solder take. You may need both types of solder. It is not possible to convert from one type (leaded or lead free) to the other. Use the solder appropriate to that already in use. Shaunie.

WolstonFlyer Posted November 30, 2013 Share Posted November 30, 2013 Is this 48W soldering station any good Shaunie? **LINK** or this one **Link** Edited By WolstonFlyer on 30/11/2013 20:03:55 Quote Link to comment Share on other sites More sharing options...
Shaunie Posted November 30, 2013 Share Posted November 30, 2013 Hi WF, Don't recommend that CPC one, I couldn't see "thermostatically controlled" anywhere, I think maybe it's just an uncontrolled iron with a lamp dimmer on it. The Maplin one looks ok though. Or try these on CPC **LINK**.There's loads here to suit any pocket. Shaunie. Quote Link to comment Share on other sites More sharing options...
Chuck Plains Posted December 1, 2013 Share Posted December 1, 2013 Maplin also do a 50w one for £20 with adjustable temperature. LINK But it may be a bit lightweight for piano wire jobs. Quote Link to comment Share on other sites More sharing options...
Shaunie Posted December 1, 2013 Share Posted December 1, 2013 Hi Chuck, Not sure about that one either, without testing one it's hard to be sure but I've an idea it's not thermostatically controlled but just temperature controlled, i.e. it's just got a lamp dimmer type controller on it and they are not the same believe me. I could be wrong but at that price... This one however would be ok **LINK** I know it's twice as much but you get what you pay for. Another little thing, people watching me solder often remark about how large a tip I use for a job but I find a large tip stores more heat energy and delivers it more quickly. Yes it does have to be used with care as it is easy to bridge pins etc. but I get better results especially with many modern SMD circuit boards that suck heat like you wouldn't believe. When I need to rework a circuit board that is difficult to get hot enough I use one of these **LINK** which is basically just a vertical heat gun in a square box. It just occurred to me that undercarriage wires could be preheated before soldering which would help the solder wet out. I might do some tests if I get time. Shaunie.

Chuck Plains Posted December 1, 2013 Share Posted December 1, 2013 Using a heat gun before soldering is an excellent idea!!! Can't really use a flame as it will probably oxidise the surface or just cover it in soot. Quote Link to comment Share on other sites More sharing options...
