I have used digital scales with great success also, but ran out of Ampreg
and so switched to West Systems and it came with
ratio pumps that replace the caps on the bottles. Personally I have found
the two separate pumps much faster and easier than
using the scales, but i am past the really big layups and for big lots the
pumps may be a pain, you will need the scales or balance
for the araldite 420, just dont forget the different ratio required.

Subject: Europa-List: Epoxy Measuring - Balances vs Digital Scale vs
Ratio Pump
Hi, I've purchased a partially complete Europa a little over a year ago and
had to put it storage until my garage/workshop was re-vamped in order to
build the kit. It is now to a point to where I can start moving my kit into
it and start working on it.
I have question about the different devices used to measure the epoxy and
wondering what most builders have done in the past. The cheapest of course
is to make the Europa mechanical balance which should be no problem (is it
quick and easy to use during a layup?) but I'm leaning towards either a
Ohaus / Sartorius digital scale with a resolution of 0.01gm (do I need that
much precision or can I get away with a lower cost 0.1gm unit?) OR a ratio
pump like a Glenmarc Portionator MBT-JR from A/S which is the most expensive
of the all the options (is it worth the cost for ease of use?).
I live in Canada so I will be using Aeropoxy resin (100:27 by weight or 3 to
1 by volume).
I would appreciable any feedback/experience that you have that would help me
make up my mind!
Thanks, Roger
