    Having had issues in removing an NRV from a primus 7 (see this thread) I managed to pick up a couple of extra long (7 1/2 inches) NRV tools which I have modified as shown below with some 'Delrin' rod.

    I find this with 'presscall's' tip about holding the tool in a vice and rotating the stove prevents (so far) any camming off the NRV

    The rod acts as a spacer to prevent wobble and slipping off the NRV - I may rack out / add spacers to the two sections of Delrin to give a more even bearing in the pump tube. DSC_2563.JPG

    Good idea! I made that with some duct-tape.

    Looks good.
    Keeping the NRV tool in the centre of the pump tube (top and bottom ) makes the successful NRV removal much easier. :thumbup:
