Bit of a gloating thread really 8) ... I won an ebay auction for 20 used vapourisers for just over £20 and gave them a good fettling. A couple were brand new with most having light use and a couple that are proving stubborn to clean out. One had a very worn jet and a few of the cleaning wires had broken tips. Overall a decent haul Gonna make a few washers and have a go at filing the broke cleaning wires and lengthen them somehow? Steve
Ah yes, the first pic shows the 19 good vaps I won and the second is with 2 I already had after the mass fettle Steve
The wires are often intact on old vapourisers, so I'm pretty sure you can get some donor wires from discarded ones.
I will keep an eye out for donors. I am keen to try and re-grind the tip to see if I can do something so fiddly I'm thinking of a Dremel and a jig of some sort? Steve.
You will need to hold the tip steady just a few mm back from the end. I grind needles with a short wire in a Dremell but any whip in the tip will just shear off the tip when it gets down to under 0.01" Be tricky to offer a stone to a rigid wire but it has to be possible. You need to run the dremmel at around 15000rpm. ::Neil::
I had good success with grinding a few tips today. I started with the dremel then went to a 600 grit diamond stone then a 1200 stone. Took about 10-15 minutes each. Also found out the brass end of the vapourisers screws off! The tube needs holding firm in a vice, almost to the point of squashing it, to be able to unscrew. Steve
Yes the brass fitting is screwed into the steel tube with a fine thread. Same thing with Tilley. It's generally not so hard to unscrew. It will give you a bit better access to the vapouriser if you intend to clean out an old one. But the top part where the actual carbonisation usually take place is still behind that choking these vapourisers have about an inch from the top. Here's a Tilley 169 vapouriser dismantled:
That little brass piece can make a handy plug to seal off a tank to carry fuel in. I have also made adaptors for them to attach a pressure gauge so I could check the accuracy of the pressure tit on a Tilley. ::Neil::
