A Cracker locomotive

<< < (21/21)

AdeV:
Arnold - that's a beaut of a runner you've got there! I was worried that she might fly off the track at the first corner, she was up to such a good clip, and sounds spot-on. She's really living up to the name "Cracker"  :thumbup:


A quick side-note about solder:

 - Olde Worlde electronics & plumbing solder were 60% tin, 40% lead, or very close to. This mixture melts readily, and re-melts readily too. You can still buy it (in the UK at least), e.g from Farnell.

 - New electronics (and maybe plumbing?) solder is a mixture of tin & copper - 99.3% tin, 0.7% copper according to the reel I have here. I believe some lead-free solders also contain silver. Lead-free generally melts at a higher temperature than the old lead/tin mix, and needs different fluxes.

The old stuff (& rosin flux, which is also pretty much considered to be evil these days) smells much better than the new stuff, and is easier to use IMHO.

Good job!

Ron, Thanks very much  :beer: - I missed your post!

Thanks once again Benni   :beer: - Don't worry about your spelling  :thumbup: - I really don't think I'm a master though; anybody can do the same; it just requires a bit of effort and persistence  :thumbup:

Cheers Ade  :beer: -  :palm: I got the tin/lead wrong way around...   :lol: - I don't know what the new solder and flux smells like, but I do know the old solder well; repaired and built many a circuit in years gone by.  The smell does get to one after an all-nighter re-soldering about 140 RS232 connectors to change them from 25 pin to 9 pin though  :lol:

Thanks kvom  :beer:

 :beer:, Arnold
