Progress report on the 1 pint Monitor blowlamp.
I have finished all the cosmetics; repainting handle + nozzle guard, derusting and brightening of screws + washers, all the brasswork to original....
Then the pump would not work. So I took it out...clogged....
The pump has two one way valves inside it. One id sealed, and the other, at the tip, unscrews.
The valve at the tip has a tiny spiral spring in it which is a cone spiral and it must have been dismantled in the past in the mists of time and the spring replaced wrong way round. Fixed that.
But the pump itself was clogged. I took out the plunger and filled the chamber with lighter fuel, soaked it overnight. A lot of black gunk came out. Still no luck.
Then I inserted a fine wire to activate the spring mechanism in the body. That worked but still clogged. Persevered.
Then I replaced the leather with a Tilley spare, because they are identical. Now the pump works at last.
Reassembled. Filled. Pumped...but the collar began to leak fuel.
So I had to dismantle the whole thing again to get at the collar..
I suspect there is a heatproof washer missing (to make the seal between the vaporiser and the tank ). So I am going to fit a Tilley washer...see what happens..
Otherwise, it is ready to belch a jet and make a roaring noise..
Will keep you posted of progress...
