Flamegun weedkiller - Sheen X300

1. Ensure vavle closed 2. 3/4 tank of paraffin Yep. 3. Heat the end near the coiled pipe on a gas barbecue (how hot, how long, necessary ?). 4. Pump up pressure to 3/4 scale, that's a guess (scale is 0-60 psi). Swap these two around, it'll cool while you pump. Don't know about the pressure. I might go for 50% to start with then adjust once I've gained experience. Not sure that the bits will get hot enough hot over a barbie. I'd expect to find a little indentation or spoon to hold about a table spoon full of meths some where near the jet/coiled pipe. 5. Open valve fully and ignite. Light the meths and when it's almost all burnt turn on the valve slowly, the burning meths should ignite the vapour. You way runs the very real risk of either have a jet of hot(ish) liquid parafin or clouds of vapour (whumpf!) or something inbetween (20' flame thrower). 6. Adjust valve for best flame. Yep, and keep it pumped up. Any other tips on maintaining and using this device. Check the jet is clear. You really need a proper pricker for that. -- Cheers Dave. |

Thanks Dave and Martin for responses.
UPDATE Not sure that the bits will get hot enough hot over a barbie. I'd expect to find a little indentation or spoon to hold about a table spoon full of meths some where near the jet/coiled pipe.

You way runs the very real risk of either have a jet of hot(ish) liquid parafin or clouds of vapour (whumpf!) or something inbetween (20' flame thrower). I've just taken it apart and cleaned it. Not in bad nick. I find a wick laying around the coil and jet. As such, I guess the technique is to soak the wick in meths, ignite the wick, then proceed after the meths is about gone. Cleanliness points noted re jet and paraffin quality. I've just poked around in the jet with a paper clip. I'll give it a go tomorrow. If OK, it's a good 20 pounds worth - they sell for ~145 online ! Cheers, Jim |

Cheers, Jim Unless methodology has changed since the days of pressure blowtorches you should soak the wick in paraffin not meths a slow burn is needed to heat the coil to raise the temperature of the paraffin beyond its flash point meths tends to burn too quickly heating the surrounding air and does not need a wick this is the type which uses meths poured into the dish below. http://uk.youtube.com/watch?v=P7tmQH9KtWM Derek |

The blast of heat will do enough damage to the plant cells for them to wilt and die back in a day or two. Even our tiddly gas powered flame gun just needs a waft over let alone a brute like an X300. -- Cheers Dave. |

I've read the same thing here. I have no personal experience of using a flame gun. I did look up the mix for making napalm but thought urg was an inappropriate place to post it ) The gardener of the household found horses tails at the allotment, that had survived more than a year of having the ground where they grew covered with dense black plastic. -- Martin Your gardener will find, as I did in England, it takes napalm to get rid of it. I took up the plants in the affected bed, which adjoined a field, trampled it with hob nailed boots, actually gold ones, and broke the tough outer covering of the "tail". I mixed a little detergent with the glycostuff, most were killed but I had to do second and third applications on others bits. Unfortunately the field was covered in it so it was only a matter of time before it encroached again. I wanted, before Contracts were exchanged, to dig up a young shrub that Sacha gave me to bring it to France. I dare not in case the dreaded weed came with it. I will buy one in France to replace the one that Sacha gave me. Judith |

I think not - although some were taken of me last night dancing - they will be destroyed a.s.a.p.; I didn't know I could look so daft!!! Now on topic - what a storm we had here last night, did you get it your way? I planted a melange of salad seeds, I wonder if they will come up in straight lines as they must have been bounced out of the soil with the force of the rain and hailstones. Judith |

Cleanliness points noted re jet and paraffin quality. I'd not worry to much about using a "refined" parafin with a nice bit of perfume added and a hefty markup on price. I'd take a few litres out of the heating oil tank... I wonder how much a gallon of paraffin is from a shed these days? Heating oil is 50p/l now. If OK, it's a good 20 pounds worth - they sell for ~145 online ! Even if it needs a new jet £20 is a bargin. -- Cheers Dave. |

I wonder how much a gallon of paraffin is from a shed these days? Heating oil is 50p/l now. Have you seen how much a new burner costs? Why would you need a new burner? A new jet is £5.99 inc VAT from Mower Magic... These things are *very* simple there is very little to go wrong that poke with a proper pricker (not a paper clip) won't sort out. Your more likely to get muck in the tank from around the filler when filling up than from the fuel itself. -- Cheers Dave. |

They are no good as a weed killer anyway. No plant can survive without top growth. The dandelions in our french drains don't like being scorched twice a year, everything else disappears. Which reminds me I need zap the french drains for the first time this year. -- Cheers Dave. |
