Flyfisher Posted July 4 Share #1 Posted July 4 Has anyone ever had any luck soldering brass to cast metal parts? I’m at the point on the Beagle where about seven pieces of brass and cast metal must be assembled. I just spent all day trying to find a way to solder them together. No luck. Any advice would be appreciated. Thanks. Jim mtaylor 1 Quote Link to comment Share on other sites More sharing options...
Gregory Posted July 5 Share #2 Posted July 5 A little more context might help. Is this a kit? Which one? Which parts? I've never seen a typical kit that suggested any soldering at all. mtaylor and Canute 2 Quote “Indecision may or may not be my problem.” ― Jimmy Buffett Current builds: Rattlesnake (Scratch From MS Plans On Hold: HMS Resolution ( AKA Ferrett ) In the Gallery: Yacht Mary, Gretel, French Cannon Link to comment Share on other sites More sharing options...
vossy Posted July 5 Share #3 Posted July 5 Use glue. Canute and mtaylor 2 Quote Link to comment Share on other sites More sharing options...
Flyfisher Posted July 5 Author Share #4 Posted July 5 Alas,that’s what I’m doing now (gluing.)I’m building the Occre Beagle and this is some part that fits on the bow. I had a wild hair to solder the pieces because my glue jobs are sloppy. Hate to offend anyone, but I’m just experimenting Canute and mtaylor 2 Quote Link to comment Share on other sites More sharing options...
Dr PR Posted July 5 Share #5 Posted July 5 I seem to recall a caution someone posted in another thread about trying to solder to cast metal parts. Some are made of low melting temperature alloys. You can buy this stuff for making castings at home. If you try to solder to them they melt. The fellow had a broken anchor from a kit and tried to solder the pieces together. The entire anchor melted. Lead and tin/lead (pewter) parts will melt at low temperature. Cast brass or bronze can be soldered to. A resistance soldering unit is best for this because it concentrates the heat quickly in the solder joint without heating the entire cast part (which could take quite a while for a large piece). wefalck, Canute, Gregory and 1 other 4 Quote Phil Current build: https://modelshipworld.com/index.php?/topic/19611-albatros-by-dr-pr-mantua-scale-140-about-1815/&tab=comments#comment-601276 Previous build: https://modelshipworld.com/index.php?/topic/19321-uss-oklahoma-city-clg-5-1971-3d-cad-model/ Link to comment Share on other sites More sharing options...
Flyfisher Posted July 5 Author Share #6 Posted July 5 Thanks. Sounds like glue is the most effective solution mtaylor and Canute 2 Quote Link to comment Share on other sites More sharing options...
wefalck Posted July 9 Share #7 Posted July 9 Soldering is joining two metal parts with another metal that has a lower melting point than the parts to be joined. There are some low-temperature solders with a melting temperature less than white-metal (which I assume are your parts). Some railway modellers solder their white-metal kits and there are some hints on the Internet concerning fluxes and solders. You also need a temperature-controlled soldering iron to make sure you stay below the melting point of white-metal. Given the risks involved when trying to solder these kits, it seems that railway modellers in general prefer epoxy cement. CA does not have sufficient gap-filling capabilities.
