And the winner is...

Hi @X246A,

I've found that out, and 100 pumps brings it level with the top of the 'tit', so full pressure was achieved.!
And I got about four hours before turning the lamp off and there was still a good amount of pressure in the tank.
Next time, I'll leave it and see how long I can get on the initial 100 pumps.

 

I had to fit a new mantle to the lamp, but noticed that when I was looking down on the burner and mantle assembly there was a corona of flame round the mantle, is this normal.?
Or have I fitted the mantle incorrectly.?

 

I doubt you've fitted the mantle incorrectly so forget that.

I've noticed this phenomena on some of my lamps when first lit but once everything is good and hot, the corona disappears.
How long had the lantern been burning when you first noticed the corona?
Was the lantern up to full pressure?

As long as there's no build-up of soot on the mantle, I wouldn't worry about it.

 

Just a few minutes and the corona has now gone. I've also noticed that the lamp is now considerably brighter having fitted a new mantle.
And the lamp was at full pressure.

 

I've just fitted a new pump to the lamp and it's performing a lot better.

Addictive, aren’t they!

Glad it is behaving itself now.

They most certainly are, though the wick lampses will still be my first love.
They're a lot easier to light for a start.!

I've just managed to get the old pump apart, and I'm in the middle of replacing the washers, so I will have a spare pump to call into service; the leather washer was very worn, so no wonder I was getting poor pump pressure.

It was a right struggle to get the leather washer off, but my little Armeg set with a 7mm socket saved the day.!
It's just the right size for the nut on the end that holds the leather washer on.

 

I had the thought yesterday, that because I now have a fully working spare brass pump that it would look good on the X246B with the brass fount, and it does.

 

@Sammi Jane

Photo please, I still like the x246b.

@X246A

Here you are...

 

@Sammi Jane

Thanks, he looks good!

@X246A
The aluminium pump just looked a bit out a place...

 

To go with the brass pump, I now have a brass control cock and retaining ring, so the next time Bill gets a major fettle I'll be replacing the aluminium ones with polished brass ones.
