• hi all, havent been on here for a while, life has been very busy as of late, but i am starting to finally get some progress going on my vw build up    im looking to balance my pistons in the very near future ( i still have to clean then and what not and i havent weighed them yet) now ive never balanced pistons before and am not really sure where to grind the weight off from, i am assuming the inside of the crown but am not sure any help or advice would be greatly appreciated thanks

• When I worked at Federal Mogul's research lab, the testing showed the lower skirts were under the least stress.
  
  So, I never remove material from the crown nor wrist pin bosses, but from the lowest part of the skirt.

• ok so the lower part of the skirt would be the best place to remove the wight from, adn no i havent weighed them yet, probably get around to dojing that on the weekeend if all goes well , and at the same time i'll weight the connecting rods to see how much they can be balanced up as well.
