Hi Guys. Progress with my Cygnus Crabber is slow but positive. I am using the old "measure twice cut once" approach to every aspect of the build and picking as many brains and taking valuable advice from people, such as your good selves, as I can ! This is one such occasion. I am fast approaching the task of soldering, which I have never done before. I am making all the steelwork of the boat, i.e. stanchions, shooting bar, 'A' frame and railings out of brass tube and rod. I have made up a wooden jig to pattern the railings and 'A' frame. I have bought enough brass to afford me some extra for "dummy runs". Now when it come to the actual soldering I see on the market is some solder paste (solder and flux mixed) called "Plumbers Mate", I've watched a couple of videos using this product and it seems as though it would suit a novice like me. The thickest rod I am using is 2mm. Do you think this product suitable and do you have any other views please ? Yours studiously !😉
First take a deep breath and calm down. Soldering is easy if your only using 2mm material I would get a reel of 60/40 cored solder. Use a decent sized electric soldering iron. Clean all your joints well ( use a fine abrasive like 600 wet and dry). Apply the iron to the joint then apply the solder remove solder remove iron. You made a joint repeat until you have done. Try not to burn yourself. Clean any flux with meths and an abrasive.

Hi Alan I make many of my fittings out of brass and provided you keep everything clean and free from oil especially from your hands the process is as Haverlock has described. I use a small pot of FR Power Flux bought from the local pound shop, it's for lead free solder but works fine with my lead cored solder. I am not a fan of the new lead free solder and find it difficult to use, so if you can try and source some cored solder that doesn't conform to the new lead free standard. At 2mm you will not need a high wattage (possibly 15-20 watts), I have a temp controlled iron so can adjust the heat. A jig to hold everything square is essential and if you are soldering near to a previous joint you may need a wet cloth or a lump of metal to act as a heat sink to protect the previous joint. Please keep us posted with your progress, many others struggle with soldering so your efforts will perhaps help them to take the plunge. Good lick Dave
Hi Dave. Thanks for the reply and info all of which is very helpful, giving me confidence to "take the bull by the horns" so to speak !!! I will definitely keep the site updated with progress. It is just having the initial confidence to take that mighty leap !!!👍😉
Thanks for your feedback and compliments gents. I seem to have had a bit of luck not being daunted by the trepidation that soldering brings !!! My Uncle builds dolls houses and has just given me an order for some brass bedsteads !!! He didn't mention if it would entail a coin of the realm being passed across my palm but the fact he wants me to make some is praise and enough reward for me !!! 😊😉
Hi, if you look on u tube, you will find lots of videos of how to solder, the thing is,, they make it look so easy! I couldn't solder for toffee, until a visit to utube. Have a look, you will be surprised. Cheers Ken
Thanks Ken I already did and I watched the video's time and time again before I attempted what you see above !!!
It's alright Marky ! Mine has a new rubber flex and has been overhauled by an electrician, thanks for your concern!!! I found I was really comfortable with it and my confidence grew with every solder !
