Haven't used it to ss a boiler yet, but I'd use supplementary heat ( blowlamp.. :clap: ) anyways to avoid using all my gas...... --- End quote --- Strange that John, I bought one of those yesterday, thanks for all the advise guys.....total cost was only £27.?? as I had the gas in the back garden, a full cylinder at that, seems to gt some heat up, just need to find something to test it on soon.... Now all i have to sort out is a little firing area...........:? |

Steve, just to add my two penneth, I got both my Sievert torches from homeworshop.org, post an advert and I expect someone will have something going spare. I have two, one came with the regulator and cost me about £10 and the other has no regulator and is just the gun and cost me about £6-8. I use two thermal thermal blocks that cost a couple of quid from BQ and they also let me have some smashed up pieces for nothing! However, I rarely use all that kit and can actually get some pretty big pieces hot enough using this BQ all in one cylinder and bottle job: http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=11248058&fh_location=//catalog01/en_GB/categories<{9372015}/categories<{9372043}/categories<{9372176}/categories<{9392053}/specificationsProductType=blowlamps I`ve found that if I spend the time to make myself a little cave of thermal blocks and put the part in, I can get most pieces i need red hot although I do often set up on the kitchen gas ring to get some extra head around it! I don`t know what silver solder you are using, but my biggest error in soldering was not getting the part hot enough, pushing the silver solder rod into the joint and hoping it would melt it. It never would and if it did, the joint was terrible. You can tell right away if it is hot enough as the solder gets sucked into the joint. Good luck. Chris |

I agree with Chris about the need for concentrating the heat- by any reasonable means. By this, I would use thermal bricks, metal shields and coke or charcoal to hold the heat in one place long enough to raise the temperature to a dull red-- and with the borax gone to a glassy liquid. As he says, his early work was like? Well, might I say old fashioned cinder toffee? So Steves, this is what you risk and all that careful work is ruined. In a normal environment, you would be given a bit of thin steel plate, told to clean it thoroughly and put on the liquid borax. Your aim in life was NOT to do something proper but merely to see a puddle of solder appear on the middle of the test piece. Then you would do another piece and perhaps stick a nut onto the sheet. Then you would move to a thicker sheet, bore a hole and put a rod into it-- and watch the solder wick its way through to the other side. It would be then- and only then that you would be allowed to progress to the real job. Once it all goes together, it is plain sailing. You then go out- look for a donkey with a missing tail, get the right flux and stick the tail back on. Well, nearly? |
