I need to mix and cast some very small volumes and am concerned about getting the right mix ration given the tolerance of my weighing apparatus.
I have a scale that only measures as low as .1 ounce. If I am mixing up 12 oz. at a time I don't suppose it makes too much difference if I have 6.1 oz A and 5.9 oz. B...at least I've never noticed anything.
The problem is when I get down to only mixing up maybe 2 oz. I suspect 1.1 A to .9 B might start to cause problems.
Can someone please tell me what the % maximum tolerance is?
I've never poured any small volume amounts of Clear Slow ...however... I have with AlumiRes (RC-3) resin.
I don't know if the exact same would apply with the clear but with the RC-3 you don't mix less than 14.1748 grams per side (A side, B side) Keep in mind the smaller amount you mix the more exact you have to be as far as equal amounts in either oz. or g. so at the amounts your wanting to do , you have to be exact. I find that measuring in Grams is more accurate than Ounces. As far as a % of maximum tolerance at those volumes there isn't any.
What I have done to over come this problem is to mix a higher amount of resin ....say 20g per side and pour additional molds.
