    I've run my Proxxon spindle many times for up to 10 hours on wax
    (10K - 20K) without any heat problems. Also no signs of the (blue)
    wax melting even using cutters which a scrape rather than shearcut,
    maximum feed rate used. 

    Proxxan spindles will die if a crash causes them to stall for hours,
    don't ask how I know.But I didn't hesitate to quickly buy a
    replacement. For anything much tougher than wax they are pretty
    wimpy.
