I am building model sailing and power yachts using the bread and butter method with mahogany, basswood and Spanish cedar. I've developed some unique rigging using a variety of materials from hardware, fishing, jewelry making and sail making. I intended to use 1/8" aluminum tubing for bow and stern pulpits and rails but i have been unsuccessful in joining the tubing. I've tried soldering, but the aluminum tube melts before the solder and when the solder I have did melt it did not adhere to the aluminum. I've tried a dozen glues. None worked. I've even tried lashing the pieces together using very thin jewelry wire but it's a pain and the result is not acceptable. Supposedly aluminum can be soldered and I remain bullish on that method but I need some guidance. What solder/flux do I need? Any special prep to ensure a good clean joint? What tool is best for this type of soldering? Where can I get the materials at a reasonable price? Is there a technique for holding these small pieces while soldering them? Please let me know how I can do this or, if you have a better idea I am open to learning. Thank you. BlueOcean
