Paul H Posted December 24, 2020 Report Share Posted December 24, 2020 Never used a blow lamp on spark plugs . What’s the best way ? Paul Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 25, 2020 Report Share Posted December 25, 2020 well first you need to remove the spark plug then you need to light the blow torch aim at the plug hold it at arms length and set fire to your overalls job done Pete 1 Link to comment Share on other sites More sharing options...
Nick Jones Posted December 25, 2020 Report Share Posted December 25, 2020 I think setting fire to your overalls is optional Pete...... I prefer not to. Aim is to heat the electrodes and insulator to the point where the deposits burn away and residue brushed away. Nick Edit: If you have an NGK plug that has stopped working after a petrol soaking (flooding), this probably won’t help. I’ve not found anything that recovers them. 1 Link to comment Share on other sites More sharing options...

I wear Nomex overalls, solves that problem. The guys at work tend to throw them away when they get dirty, so I stand in the way. 🙂 1 Link to comment Share on other sites More sharing options...

It`s a very "interesting" exercise, Involving several Firebricks lots of Flux Powder. And the biggest blowlamp ever built?. The end result remained intact until the replacement was finally airlifted to us 3 weeks later.👍 Pete Link to comment Share on other sites More sharing options...
Pete Lewis Posted December 26, 2020 Report Share Posted December 26, 2020 remember as apprentice we needed a new head on the lead mallet, so off to the body line nick some lead sticks, get the blowtorch aimed at a old tin can and melt lead into the tin looking at plunging the handle in when all hell broke loose , we had cooked the lead and the training school was engulfed half way down from the ceiling with thick green smog we were unaware the drawing office above us had to be evacuated we all got a right rollocking so blow torches for braizing have a soft spot in the learning curve Pete Link to comment Share on other sites More sharing options...
