The goal of this was to remove the "wheel" which locks the trigger. After I bought this, I found unlocking this trigger took some practice and I didn't like the way it made using the lighter so difficult. Of course your situation may be different. We have no children on the premises so I didn't mind leaving this trigger interlocking device off.

My disassembly instructions are brief and in some ways redundant to the more detailed step-by-step Scripto Lighter breakdown  posted by an earlier writer at: http://www.instructables.com/id/Scripto-Lighter-Teardown/

As this is my first DIY instructable I wanted to practice photographing a project that had small pieces and using a SmartPhone camera. The phone is a T-Mobile Huawei called MyTouch. The Smartphone's camera is helped by viewing the small objects through a handheld strong magnifying glass. No flash was used. All photographs were done with the morning sunlight pouring through a window.

First, remove the small Philip's screw with a Jeweler's screwdriver, which comes in sets from places like Radio Shack. There is only this one screw.

Thank you so much. We need the lighter for the stove on our boat. My
wife has a little arthritis and could not use the lighter. I am going
to pick up a few more of these, now that I can remove the wheel for my

FlagPole, You're welcome.

Another use for the lighter.

After the butane fluid is
used up, the lighter spark generated is very handy for lighting my
propane torch or natural gas kitchen stoves. The kitchen stove is a
pre-1960 stove designed with a constantly burning gas pilot light. The
pilot light we shut off. We light the top burners when cooking with the
spark of this lighter, no flame just the spark. This is
not as instantaneous as when the pilot light was left on. There is a
delay as the gas has to flow and mix with the oxygen and might be as
slow as 8 seconds after turning the knob.

Sometimes you'll have
to shut it off and start again. When a pot is on the stove covering the
burner area, it seems to light more quickly. We learned of lighting
stoves with the piezo electric spark from these lighters while living in
an apartment in Paris, France in the 1980s.

But it doesn't work for lighting the oven nor the broiler. We keep the pilot on for that.

A correction about my comment that lighting the kitchen stove with the electronic spark from lighter and not the flame from this lighter. I said it can take as long as 8 seconds. That's 8 seconds is sometimes true but it varies from lighting right away to four seconds on the average.

Thanks Ringai. Glad to know I'm not the only one woo dislikes the lock! Iinspecting the design it seems even if that locking wheel were easier to operate, it's placed a bit too far forward, making it awkward for people with smaller hands.

Thanks! Now I know which brand of lighter to get. I hate the thumwheel :-)

Your pictures turned out great.
