    Hello Alma.  My set-up uses a Rey Vacucast because I wanted the
    option down the road to vacuum cast with an Electromelt perhaps. 
    However, I use the spin-caster so far.  No problems with either over
    a 20 year span.  I use the Vacucast only for investing. 

    It is absolutely true that you can fuse a crucible to the flask with
    too much metal.  Another person where I teach used to operate on the
    assumption that more is better (NOT) and added "extra" metal for
    insurance many times or didn't weigh the models and calculate
    accurately.  It is also possible to forget to make note of the
    capacity for those crucibles - both in silver and in gold.  At any
    rate, losing a crucible to breakage is bad enough, but the enormous
    time it takes to grind away all that spilled metal isn't funny. 
    Also, if it spills out the sides and you see molten metal flying
    around in there, you won't like it either. Morale of the story -
    calculate the metal needs very carefully and check it twice.  Know
    the capacity of crucible and do not exceed it.  Check the fit of
    every flask you place in it.  Certain flasks are intended for the
    Neycraft diameters - don't use just any old thing. 

    That Neycraft spincaster is very efficient and long-lived when used
    with respect.  It is also wonderfully safe and was developed for that
    reason and is used in our teaching facility for that reason.  The
    big ones with deep tubs and lids may look safer, but I don't believe
    you'll need more safety than the Neycraft provides.  I've never had
    a complaint or problem with mine. 

    Best of luck in your casting.  Enjoy it as much as I do.
