I recently got a fire piston from my sister as a gift. She also got one for my father and her husband. They tried to use it, but couldn't get the charred cloth to ignite. Then I gave it a try. I cleaned all of the oil off the piston, put some char cloth in it, and rammed away... To no avail. You guys make it look too easy. With one stroke out pops a burning cherry. Not so in my case- I couldn't even get the piston to bottom out because of the pressure. I would pull the piston back out and it was room temperature. I then tried to pump the fire piston furiously, and the outer casing would start to get hot, but when I pulled the piston back out, there was no fire. My brother-in-law used a mallot to try to get his piston to bottom out, but it made no difference. What are we doing wrong?
