Ive balanced somany cranks assys I cant even think of how many, many machines do a ok job some do a great job and nomater what machine the balance job is no better than the person doing it. some machines dont get down far enough, just good enough...and some guys dont like to spend the time to do it right even if they know how. or they try to sell you a stock balance job, or a street balance job , or a prostreet balance job or a race or super race balance job. well it's either balanced or not when you come uppon somebody doing all these different balance jobe get your **** and run. ive been without my balancer foe about 10 years now and I miss it dearly,I only do my own stuff nowdays in my shop, but that is one peice of equipment that I nolonger have my fingers on that I wish I still had. I dont relly like the first unit shown, but I havent used it, it would be nice to see what it really does and the repeatability. I can already see the operator dosnt know how to do it right....so sad.and the customer hasent a clue it isant what he thinks it will be.
