hot glue piston

Unread postAuthor: maz oner » Tue Jan 30, 2007 4:32 am

Ive made a piston by chopping up hot glue sticks into little pieces and put into a piece of spare copper tube, (chamber size) then heated the whole thing up with my blowtorch :twisted: untill it all melted now i cant get it out of the tube, its glued in like glue (as it is)
how does every one els take them out without cutting the tube
i might go heat it up a little so the outside melts a but then push it out but any help greatly appreciated

Next time, a little bit of grease on the inside of the copper pipe will prevent the glue from adhering to it.
