Ernie Posted September 14, 2020 Share Posted September 14, 2020 I've searched the web, both high and low for the wire with a horn soldered onto it, that is used to join elevator halves together I do feel a bit of a wimp for not making one, but it is such a critical wee component, that I don't want to chance bin bagging my latest jewel due to my dodgy silver soldering skills where can I find one? ernie Quote Link to comment Share on other sites More sharing options...

perttime Posted September 14, 2020 Share Posted September 14, 2020 I believe people mostly don't use elevator control horns that are attached to the joiner wire. What are you building? Are you sure you need one? The first one I could find online was on the (Control Line Stunt) supplier RSM Distribution in USA **LINK** (Select 'Building Supplies' -> 'Control Horns' ) Edited By perttime on 14/09/2020 16:00:49 Quote Link to comment Share on other sites More sharing options...

I'm afraid that if you find the Flair part at a model shop or online it will be old stock. I think you should get your gas torch and silver solder out Ernie....

John Wagg Posted September 14, 2020 Share Posted September 14, 2020 i made mine using a bit of tube soldered to a piece of piano wire. Quote Link to comment Share on other sites More sharing options...

Nigel R Posted September 14, 2020 Share Posted September 14, 2020 I have seen a pair of aileron torque rods used for this. Imagine two of these chaps sat next to each other with the threaded upright bits touching. One gets the threaded bit nipped off. Both are then bound and soldered together just below the thread. The standard screw on horn is then put on the remaining thread. Easy to do and does not rely on only the solder joint to transfer the torque.

Stuphedd Posted September 14, 2020 Share Posted September 14, 2020 I normally use that type of elevator "horn" on models where I want to hide it inside the fuz. for lightish models 25-30 powered , I just bend the piano wire in half there will be a loop produced , Put the loop in the vice and twist the two rods together untill the required horn length is reached then bend them at right angles opposite each other and then bend them to fit into the elevator , I do fill the loop with silver solder so as to drill the hole exactly 1/16" bigger ones I actually trust hard silver soldering a brass horn onto the wire no failures in umpteen decades ..

Peter Miller Posted September 14, 2020 Share Posted September 14, 2020 When soldering a strip of brass to the wire silver solder is vital. We used to make out own for controlline stunt models Quote Link to comment Share on other sites More sharing options...
Ernie Posted September 15, 2020 Author Share Posted September 15, 2020 good morning guys, and thanks a zillion for your help and interest Keith, thats exactly what I need, alas, I never get anywhere with Flair, perhaps I'll try yet again. Yes Denis, thats what I need, Its for the Fury that I'm building with Danny Fenton. I'm way behind, but still plugging away Thats the sort of thing John, I've spent a lot of time, so I want something substantial, and yes Peter Miller and Stuphedd, its going to be a home made silver soldered joint ernie Quote Link to comment Share on other sites More sharing options...

Trevor Posted September 15, 2020 Share Posted September 15, 2020 Silver soldering isn't my strength so, since the wire gauge is usually a bit heavy for Stuphedd's twist and drill method, I make the joiner in two halves, grind a flat on the inboard faces of the vertical sections, then hammer on a length of brass tube. The overhanging end of the tube is flattened and drilled to take a clevis, then the whole lot glued together with epoxy. This method has proved very reliable over the years - a few examples below.

FlyinBrian Posted September 15, 2020 Share Posted September 15, 2020 Surely If you bind the joint with copper wire prior to soldering it would be strong enough?? Quote Link to comment Share on other sites More sharing options...
Peter Miller Posted September 15, 2020 Share Posted September 15, 2020 If you can't silver solder there is a way that works quite well and even if some of the solder gives it will provide some elevator control Take your piece of brass and drill the hole for the wire. Now drill a second hole just touching it to give a figure eight hole. Slide your elevator joiner into the tophole and a short peice of the same wire into the lower hole. Bind firmly with tinned copper wire and then solder everything properly. This will give a better joint that just a drilled hole which has no mechanical way of stopping rotation Quote Link to comment Share on other sites More sharing options...
Bert Posted September 15, 2020 Share Posted September 15, 2020 Ernie, If you send me a sketch of what you want, with some dimensions I will happily make you a couple of them FOC. Bert Quote Link to comment Share on other sites More sharing options...
Ernie Posted September 16, 2020 Author Share Posted September 16, 2020 Bert, that's incredibly kind of you, but not yet. I'll have a go myself. I've found a nice wee bit of steel, and some piano wire, all around the correct thickness. As ever the first big problem is where did I put the silver solder, and is that white powder flux or cocaine Trevor, that looks perfectly possible, It shall be plan B ernie Quote Link to comment Share on other sites More sharing options...
Bert Posted September 16, 2020 Share Posted September 16, 2020 Ernie Just keep it in mind, if you need it. Bert Quote Link to comment Share on other sites More sharing options...
