Hopefully most of you will know what this is? It`s a swan neck from what they term as a "hobby" welder.
Now i`m not saying i get through a lot of these but i have just broke my second one by welding the wire to the tip and trying to remove the tip.

If you ever need to replace one, it`ll cost you over a tenner, i know cos i bought one last week.
Lets see what you get for your money, a piece of brass tube with a couple of threads in, some holes and a rubber sleeve, HMMM think we can make one?
First thing we need then is the raw material, 8mm brass bar, this will cost you that same ten pound note but for that you get a metre of the stuff, enough to make 6 necks!

Measure the length of your old swan neck, should be around 140mm, and cut the brass rod to length.

Tricky part next, you need to drill a 4mm hole through the length of the bar. This is the part that had me stumped for a bit, but after seeking advice (cheers Doc), about the only way to do this is to drill down one end, then flip it over and drill down the other to meet in the middle. Ordinary drill bits are around 75mm long (this is what i used) but long series bits are available and would be better.  Ok OK, it did take me 3 attempts before i got this right, the drill bit had a habit of wandering off centre and out the side of the bar. SLOW and STEADY is the way to do it. |

Almost there now.
The welding tip needs to screw in the end, and i need to cross drill the gas holes and then pretty it up before bending to shape, but time caught up with me, so more on this later.
