things are not right, and when you do test it, you=99ll often find
it will need adjustment. My view, they are rubbish. Don=99t do it!
Sorry Dave, I=99ll compensate by paying the trash fee. Nothing
beats a set of digital scales.
I too have a discarded and gummed up resin dispenser pumpand
though i have no weigh (just couldn=99t resist) of precisely
comparing my balance beam w/ a digital scale, one of the advantages of
the balance beam is that its use completely eliminates the necessity of
precise quantity measurements of both resin and hardenera very
useful advantage when =9Cjust enough=9D epoxy is
requiredand as for sensitivity, it=99s always gratifying
to see the beam balancing out after adding only the tiniest amount of
hardener.
It was quite easy to mark the beam so it could be used for different
epoxy ratios.
I would not trade my balance for even the priciest of digital scales.
