Making fire piston is not really difficult as it seems.Its just the matter to follow few conditions , such as.. 1. The cylinder diameter must not be more than 1/2 ", if its more then its becomes almost impossible to create the required pressure using hand strength.The ideal diameter is from 3/8" to 1/2".Remember more the diameter means more pressure is required. 2.Even though O rings produce good seal,to get O ring of correct size is tricky. Thats why I prefer thread gaskets. 3.Use of good char cloth is essential. It must be made up of cotton fabric and must be dry.
