didnt know this thread was still here, saves me having to start another!

now we have the bigger ram in merlin we need to fit in somes buffers. Im currently thinking of 2 sodastream bottles, as they are about the right physical size and have a handy 1/2bsp thread! ive got the bottles and emptied them, but i now need to remove the valve in the end, im assuming it just screws out? i want to make sure before i blow myself then length of the garage! or does anybody have anything already, about the same size?

cheers
