I'm planning to build a peanut lighter with a friend's birthday coming up. I'm not the birthday gift giving type really, but the guy got me a Sega Game Gear (of all things) for mine and I want to return the favour.
I built one almost immediately after I got my lathe, no idea where it is now, and it worked fairly well. One problem though was the tight fit with the sleeve part that slides out of the body, it needs to be tight so it doesn't fall out but it was difficult to remove and had a habit of ejecting all the fuel like a piston as you inserted it. I figured i'd try replace this with a relatively loose fit and an O-ring to give it a grip, but i'm unsure what kind of O-rings you need to buy that can resist petrol/ lighter fluid.
Any help would be appreciated.
