Help with “scorching” problem

[NCJim]

So, I have a “scorching” problem—and I don’t mean our hot weather. My wife has some pine craft items that she’d like me to scorch. Years ago, I did these many times without any trouble. Last week, I pulled out my better trigger-controlled propane torch head, which I hadn’t used in more than 20 years. When I tilted it slightly, the flame went out. I knew that wasn’t normal because, back in the day, I soldered plenty of copper pipe at all angles without issue. So, I bought a simple torch head instead of replacing one like I already own, especially since I may not use it again for another 20 years.

So, what am I doing wrong? I tried my heat gun with poor results, and I don’t have any “scorching gel” and never used it before. I would like to get this project done ASAP.

Any advice?

Not sure what your question is. Are you asking about the torch problem or the technique using a simple torch head?

Are you using a new tank of gas or an old one? If the latter try a new can.

Torch problem. I think I know the technique ok but any advice would help. Thank you.

I am using a older tank but not that old maybe a couple of years old. I thyed 3 differents but they were purchased all the same time. I have a propane heater purchased them for that but since then I have the heater in a 20lb. tank. So maybe the tanks are too old? The turns off only when I tip the torch. So, maybe try a new tank?

My two cents is get a fresh tank. I have had issues with older tanks.

For large areas, (i.e. plywood sheet) I have found this style of torch to be easier for getting an uniform coloring. It puts out a larger plume of heated air than the modern ones I have used. I use naptha in mine rather than gasoline. I will admit it has been a while since I have done any.

I had a similar issue where I couldn't get a good amount of heat out of a BernzOmatic torch and I tried a separate bottle but that didn't help either. After further examination, I discovered a spider had built a web inside the torch head and was restricting airflow causing the gas to burn but not getting the proper air to fuel mixture! You might double check inside the torch head to make sure there's nothing restricting air flow.

Propane torches burn gas which in the tank is compressed to a liquid. Tilting the tank allows liquid propane into the burn tube and shuts off the gas. To keep the gas burning you must hold the tube upright. If you really need to tilt the flame there are accessories such as a hose that allows the tank to sit upright while you tilt the torch on the hose. When the tank gets nearer empty you can tilt a little since there is less chance of the liquid entering the tube. Bottom line raise the table so you can point the torch upwards and it will burn well.

might try a simple weed burner. you can use with existing 20lb tank. they aren't much on amazon or the like.

and quite frankly it's pretty cool to feel like you got a flame thrower.

obvious disclaimer is be careful and smart with it. it will torch you, your house and pets easily.
