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

Digital postal scale........
 

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.

what kind of capacity do I need??

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.
