This nice Glass oil lamp came my way yesterday. Old, complete and with a decent wick.
The wick holder is a odd designe, it has a flip top lid.
The chimley is not original. This meant I had to "tweek" the fingers to fit the glass.
Glass cleaned up well.

Got your money's worth there!
Like us mere mortals would use a hosepipe.......how to fix a frozen steel dribbleView attachment 375086View attachment 375087View attachment 375088..........just a trim with the lance should do it

This nice Tlley heater came my way, yesterday.
I knew it woukd not need much work. But I choose to give it a service. Only as I knew it may off bean bounced around in the back of a van.
The pump washer looked brand new. So a bit of ground nut oil and that was that.
I do have brand new pre heater cups. But I think the older ones work better.
There was on issue the vaperizor tube was a bit loose. So it was removed and a new seal fitted. Again not an issue.
The heater is alive and pushing out a good deal of heat.

This fire lighter came my way.
Next to nowt on WWW.
But I had time.
A few of the many pin prick size holes. The insides were cleaned with rust remover, more holes. The Citric acid. No more holes.
Then a tank sealer I use on Oil lamps, such as Tilley Lamps.
This sealed the holes.
ll done.

My coffee would have stripped the writing off it.

Oh a weak brew then.
I told my friend a TYA brew would put hairs on her chest.
She scoffed.
She does not scoff any more.

Wasn't that a Eurovision winner?

More PPM rather than fixed, but did fix a couple of little niggles whil I had tools out. Over in Ireland this week doing a bit of servicing work at a customers site.
Lots of seals on unions, new inners on butterfly valves, nrvs, SSVs, mechanical seals on pumps and agitators.

If you saw it win then it serves you right for watching.

I didn't see it at the time, but it was hard to miss the coverage later.
I've never knowingly watched Eurovision.

A while ago, I rescued one of those battery-operated pistol-grip air compressors from a skip at work - as soon as you plugged the battery in, the pump would run.
It has a built-in controller that allows you to preset the pressure in whatever units you fancy - psi, Bar, kpa etc. - and then shuts off when it reaches the figure.
It would still pump air, you just had to whip the battery out when you'd finished. Given some of the locations it got used on jobs though, it was less than ideal so it was skipped.
I stripped it down and found a MOSFET on the controller board that had gone short-circuit. That would be a surface-mount MOSFET, about 8mm square. That I could barely see, never mind read.
I used the Hubble telescope to get the part number off it (MDD1501, rated for about 30A!) and then found that nobody in the UK, or Europe or indeed this solar system has any. Luckily someone in China had them on Ebay, five for a couple of quid, so I punted my wad into the ether and expected to be disappointed.
Unbelievably, in a matter of a couple of weeks, a small envelope arrived bearing the requisite components. I duly scrounged the SMD rework station from the office and set myself up in the kitchen at Wedg1e Villas. First I used some isopropyl alcohol to clear away some oxidation that was present around the board, then it was the work of mere moments, once I'd armed myself with one of those 'mongnifiers' - you know, a headband with clip-in high-power lenses that makes you look like some kind of stamp-collecting pervert - and got the hot air gun at 480C, way beyond what my 50W Antex could do, to desolder the MOSFET.
Then I used my Hands Like A Paedophile (tm) to carefully position the replacement trannie and melted some soldery goodness.
Leaving all the guts hanging out like a freshly-Scania'd hedgehog I clipped the battery on and - nothing. Which was a good start. The display lit up, I pressed some buttons and then the trigger. Sod-all happened
Right then.
Out with the sort of magnifier a chap needs after a long walk in the cold and I realised that the corrosion I'd cleaned off had actually been worse than I thought, and a transistor near the MOSFET only had two of its three leads! As I didn't have any spare SMD transistors to hand I thought I'd see if I could clean up the raggy stump of lead and get some solder on to reconnect it to the track. Pressed the trigger: still nothing. Bums, I said.
Testing with a multimeter (and when working around SMD stuff with a magnifier on, meter probes look like scaffold pipes) revealed that there was no connecton between the corroded transistor and the new MOSFET, despite them being coupled by a 1200 Ohm resistor. That bloody corrosion had eaten the metallic pad off one end of the ceramic resistor, which must measure all of 2 x 1mm! I desoldered it and rummaged in my spares racks that have followed me around since I got into electronics in '82 and found a resistor of the right value - but of course it was a full-size, wire-ended thing, a monster in comparison! Luckily, although my eyes are shot, my joints creak and I have tinnitus that sounds like a dentist's drill in the next room I still have a steady hand so with a bit of fiddling I got the new resistor in...
And it only bloody works! Choose your units, preset your pressure, press the trigger and watch the digits count up until the pump cuts out.
Whoever chucked it also saw fit to include the carry case, charger, fag lighter adapter etc. - so I can throw it in one of the bike panniers for the next time one of our squad gets a puncture in the middle of nowhere. Soon be spring
