I've been trying to find what is needed for making my own turnouts, without having to order from overseas. I have no idea what to use for wooden ties. I was planning to use the Peco flex track, but now I'm confused at the code... is it 55 or 60 or...? I need my hand laid turnouts (if I choose that instead of Märklin turnouts) to match the flex track. Would it be better to buy some flextrack made for N to get the right code rail and remove that from the ties? Also, the rails are nickle silver? What do I need to use as solder and flux? I've made silver jewellery, but that uses an open flame, not a soldering iron, so I'm not sure what to look for. Is it regular electronics solder and flux?
