Many beginners are scared off by the process of soldering. Working with high heat and small objects is understandably intimidating, but with care and practice is very safe and simple. Soldering both strengthens metal joints and enhances electrical conductivity.
- Most modeling projects can be accomplished using simple and inexpensive tools and materials. A small 100 Watt iron or gun is adequate for most track and wiring projects. A variable Watt gun with higher outputs is a good investment especially if you work in larger scales or use larger wire. Simple irons and guns can usually be found for as low as $10.
- Resistance soldering tools are best for assembling etched metal kits or working with extremely small parts on the workbench. These tools can be found through electronics and hobby tool retailers.
- A rosin-core solder and flux paste are the other main ingredients. Flux helps solder flow much more quickly and smoothly and is key to getting smooth joints with a minimum of solder.
- Add a sanding block to clean parts before and after soldering, a couple of heat-sinks for working in tight areas around other solder joints you don't want to melt, and you've got everything you need.
