Can someone recommend a reasonably priced scale for measuring rods/pins and such?

Need it for following Wayne's procedure for balancing rotating mass of rods/pistons. The parts came with no disassembly notes from mechanic so I have not idea which rods/pistons came from where on the crank. Thanks

I got one from Staples for less than $40 and very reliable and accurate for the kind of work we do. The reproducibility of the weight readings is very reliable. Mine is the 5 lb. digital postal scale Dymo brand name with 1 gram increments.

Digital diet scales do well to. Measure in both ounces and grams, your option.

I got a scale years ago that is digital and goes to the .01 grams. Repeatable and precise. Cost about $100-200 on amazon. I had my hole assembly balanced with in .5 grams by shuffling the parts as needed. The rest will be zero balanced.

I have a digital diet scale but it only measures to the nearest whole gram so it might not be accurate enough (or is it?) . I'll checkout Amazon and Staples thank you.

0.1g accuracy is what you want. Porsche specs like 9-11 grams tolerance. But with a little Tetris style skill you can usually get to within one gram. With a little more work, .5g front to back and side to side is easy. Put the heaviest stuff closest to the flywheel.

The heaviest component will be the pistons. My 3.6 pistons were 550grams if i recall.

The 3 beam ones will measure a dust particle ..almost.
They are very very accurate.
Sometimes for an item too heavy for the scale i fabricate a small extra weight.
Nothing elaborate just hang it on there.
usually, you are shooting for all the "same weights"
Find the lightest and make all weigh the same .
usually.

I got a digital scale from Harbor Freight that measures from .1 gram to max of 500 grams (I believe). It was less than $15. Note that some places consider these types of scales as "drug paraphernalia" so you do not want to be driving around with one on your dash.
