    Where is a good place to buy a digital scale? Summit has them listed for $100 and $110 for 2000g and 3000g ones in 1g increments. Got to be something similar, cheaper out there. Ebay didn't show me much. Want to assemble my pistons and rods then prep them all to the same weight.

    Yeah when asking in class where to get a scale I just asked "so who is a coke head here?"

    you might be better off letting a machine shop do it, then they can enter in the weights into their balancing machine. And balance the crankshaft.

    Thats the plan but why pay a machine shop to do it when I can do it myself for the cost of supplies? Should I pay them to prep my block, and assemble my motor too even though I'm completely capable of doing it for free? If I buy a scale now, I can do this over and over. I'm 19 and I've already put together 3 small blocks, and will be doing many more in my lifetime.

    www.stealitback.com is a police auction site, and has a scary amount of digital scales and grow lights. Most scales are like pocket scales(duh).

    I used too have a few digital scales, but I have no need for them anymore, LOL.

    First off, all the components on the engine will be balanced together. You'll get a sheet back that says how everything was balanced, in the unlikely event you need to replace a rod or something, it can be done without re-balancing everything. I've got the machine shop sheet around here somewhere...

    That's a small part of the balancing process IMO, but above and beyond that, talk to a machine shop that does balancing. It's not a simple matter of the parts weighing the same from you just removing material. rod balancing

    Balancing was about $100 for my engine.

    as I understand balancing, they place your rotating assembly on the balancer. Namely your crank, balancer, and flexplate or flywheel. Then they place weights on your rod journals that are the same weight as your piston rod assembly and spin it. Remove weight as needed on crank counterweights and you have a balanced assembly. I'm talking about just cleaning up my rods and pistons(go to Standard Abrasive's website and look at their Block, Crank, Rod, Piston, and Cylinder head prep sections) and just trying to get them to a standard balanced weight to make it easy.

    I've watched Coonie's racing engines prep stock rods many times. He hangs the rod journal on a "tube looking thing" that allows it to turn freely and then weighs the piston end of the rod. After that he hangs the piston end on another "tube looking thing" and weighs the other end. He does this with all of them in the set and matches them to the lightest one by polishing on each end. This is all done after removing any casting flash and other things on the rod itself that are not satisfactory. It's a time consuming task. Good luck. I'd probably try it myself some time if I didn't have them to do all my stuff.

    Balancing a motor consist of more they wighing pistons. Balancing has mostly to do with adding/removing weight from the cranks counter wieghts. You need a $25000 machine to do this.
    Internally balancing my camaros engines was only like 125 bux any way...when you figure i spent $3000+ on it, its no much
