    hw95 tuning help

    hi
    i have aquired second hand a v mach piston that has the delrin bands, these bands are loose, so i have removed and cleaned under them, i need to know what to stick them back on with, or will they need new ones, plus i have cleaned and polished all internals, my other question is, should the piston run smoothly through the body or should you have to push it through gently, how much resistance does the piston have, i would ask v mach but i know they are busy and it would be quicker on here cheers

    Can't help with an actual v mach piston, but other Pistons I have that have bands, all have loose bands, i.e not stuck down.
    Hope this helps

    The bands (bearings) will likely tighten up to a slightly snugger fit when the piston is fitted back into the comp tube, don't stick them down.

    If you add glue the bands will end up bigger/tighter than you want. You'd need to put the piston in a lathe and re-size. Leave them loose
