West System sells a small batch scale that has the ratios for the various hardners written right on the scale. It costs $40 and measures down to .1 grams. Works great, a whole lot less waste than full stokes on the pumps.
I went to the local West Marine store and picked up this little scale. For anyone else interested it is a great set up for what we do. Thanks for the suggestion. And thanks to everyone else for their input.
