A triple beam scale will measure to a finer tolerance ( tenths of a gram and up to 2610 grams with the extra weights ) for under $100.00 cdn used. I went this route for my engine parts. I didn't want to spend $200.00 + for a scale that measured in 2 tenths and only up to 200 grams. a piston weighs 450 grams + and rods are 600 +
I bought mine from e-bay for $50.00 US and had it within a week of my purchase. I use mine every day to weigh #4 - 3/8\" screws into batches . I rigged up a dental floss jig to weigh each rod end to exact tolerances when I did my motor.
Here is one on e-bay. Have it shipped to Haggens in Blaine and pay them $3.00 for taking a shipment for you. Try to go around 1:00 in the afternoon on a week day at the truck crossing, and it will only take you 15 min to go across and be back.
