Here is my 20 year old Bergs Hobbies X200 kit. Which I started 20 years ago and stopped after assembling the bottom half of the loco. https://en.wikipedia.org/wiki/New_South_Wales_X200_class_locomotive Tonight I started on the engine hood. Struggled with the solder iron temps a bit (https://www.jaycar.com.au/60w-esd-safe-soldering-station-with-led-temperature-display/p/TS1640). Switching from the conical tip to https://www.jaycar.com.au/tip-ts1640-3-0mm-bevel/p/TS1644 made a big difference too. Much easier to flow solder now. I am using Carrs 90c temp solder and found I have had to set my iron about 245c to get it to melt the solder and heat the piece up quick enough to run the solder nicely without nearly burning my fingers. I started out at iron temp 90c and it melted the solder so slowly.. getting it to run on a test on the base piece was near impossible. So slowly stepped the temps up in 10'c increments. I can get the solder to go molten at say 130'c or there about; but it takes a long time to get it to run on the piece. With the iron set at 245'c I feel as though I am close to the melting point of the white metal pieces.. some tests on unseen parts didn't result in any melting.. So I guess its ok-ish. What temps do other people solder mostly white metal kits at? I possibly need to clean the pieces more. And had to keep reminding myself to flux more. Later in the evening things came together better and I was able to get some joins made without 5-7 attempts. The first piece for the engine compartment was a exercise in frustration and tweaks to the iron settings, how im holding things, how im securing things to my working timber and the lack of suitable tools to square up pieces (machinist/engineers set square in the mail..). Here are some photos of the in progress model. https://www.dropbox.com/scl/fi/z2ow...6945.JPG?rlkey=xjb8x0z142zxpm1nub2k7lngx&dl=0 https://www.dropbox.com/scl/fi/cz7h...4113.JPG?rlkey=m7icl3wubdhp4oirwcazsfmmq&dl=0 Overall learnt lots, didn't melt anything (just excess solder I had to file off and try again). And had fun. First time soldering anything in 20 years too. All of the base plate was soldered with a oxy/lpg torch and picks to place the solder, I redid some joins this evening as practice. I stopped working on the kit before I got onto the finer parts back in the day because I didn't have a soldering iron.
