Miniature locking wire hose clips
« on: June 16, 2021, 04:14:51 PM »
Most of you will be familiar with this style of aviation locking wire twisting pliers. They are now freely available from e-bay or Amazon for less than £10, dollars or Euro. They are great for locking pre-drilled nuts and bolts and always produce a neat result. The wire tail should always be turned in to prevent stabbing your fingers.








I am sure we all have tried to use locking wire, from time to time, as an alternative to those big unsightly hose clips. The aviation locking wire pliers dont always give the most satisfactory results. However here is another simple wire tensioning tool, which is ideal for making miniature locking wire hose clips, as shown below.





This wire tensioner is very quick and simple to make from a M6 bolt, wingnut and a couple of short piece of steel rod.





The M6 bolt is drilled to a depth of about 15mm, The steel rod should be a loose fit inside the bolt hole and free to rotate. One end of the steel rod has a point to act as a pivot inside the drilled hole; the other end has a Vee notch, like a birds beak. The wing nut has small holes drilled in the two ears. Thats all there is to it.






This is the miniature locking wire hose clamp tool I made this morning. It's small and intended for standard 0.7 mm stainless steel locking wire. I could make a bigger and stronger version, using an M8 or M10 bolt, if I wanted to use 1.0 mm or even 1.5 mm galvanized fence wire for the water hoses on a full size engine.











If anyone is interested, I will do a step by step run through of how to produce these neat miniature hose clams using this simple little tool.

The clamps look terrific! I'd love to see a step by step picture set. In the meantime I will make a tool per your pic. I will also try and noodle out the 'round and round over and back and the eel pops up through the hole' - sort of knotting process. Thanks, and cheers!   :cheers:

edit - I think it may be "eels" rather than "eel" in this case, on further study......... :noidea:

That looks interesting  :) Worm drive clips are unsightly in smaller sizes and I have been using fuel pipe spring clips but they are not the best.

More pictures would be most welcome  :ThumbsUp:  :ThumbsUp:
Best regards

Wow!  That is a cute little tool!  I'd love to see some pics on how to use it to make that neat looking wire clamp you have there.

Marv,

I did not know that you had already written something about making wire hose clips. That must have been a while ago, before my time.

As you say, there are a number of over priced (and over engineered ??) commercial tools available, the idea of making wire hose clips is far from new.

My intention was to design and make a very simple, wire tension and bending tool and to make it small enough for use on our model engines. The design can allways be scaled up for use with larger wire sizes.

So how do you use my small locking wire hose clip maker?

I start by cutting a length of standard 0.7 mm diameter stainless steel locking wire. The wire length should be at least 24 times the diameter of the rubber hose. 10 mm diameter hose in my example.





The locking wire is bent double, more or less in the middle.





The loop is bent around the hose and the two wire ends are passed through the loop for the first time.








The wire loop is is tightened over the hose before the wire ends are passed through the loop for the second time. Check that there are no wire crossovers





The tensioning tool is put in place, with the birds beak Vee slot resting on the wire loop. The two ends of the wire are pulled through the holes in the wing nut. The wire ends are then given 4 or 5 twists to secure the ends. Twisting the wire loosely by hand is enough.







The central bolt is now turned to tension the wire ends. It is a good idea to check the lay of the wire around the rubber hose early on and adjust as necessary. Continue applying tension until the wire is slightly compressed into the rubber hose. Dont overdo the tension or you can cut through the rubber, like a cheese wire.





When you have achieved adequate tension, simply flip the tool forward though 180*to lock off the wire.







Cut the two wires to release the tool. Trim the wire ends shorter, if necessary, and press both ends down neatly, between the wire loops.







Thats it, job and finish. It actually takes less time to do, than explaining how to do it.


It's also possible to make three wire passes through the loop, which makes for an even prettier wire hose clip and a more even distribution of pressure on the rubber hose.





It is also possible to lash two solid metal rods, tightly together using this little tool.





One word of caution. the wire ends are sharp and you can easily puncture yourself, thereby releasing endless quantities of the red stuff.

Make one and have fun.

Mike

You are more than welcome.  :ThumbsUp:

Another thanks. I have needed this tool (and method) in the past. The pictures are very clear.   --Tim

Thanks for taking the time to make the write up, Mike.  Very clear and concise!
I'll be filing this one away for future use for sure.
