You can add 40 grams to the center area of the crank throw that you'll install the rod on----if its #1 or #8 pretty much piece of cake-------a 5/64 welding rod weighs one gram per inch so you can take a couple of pieces just over 20 inches long, bend a kink at 20 inch mark and weld on----------many front and rear throws have lightening holes so is a good place to add weight back-----

and then use a bob weight that is 40 grams lighter--------[/QUOTE]



Welding on the outsides of the rod journal on the crank? I am confused on what exactly you're trying to say. The rod is from Childs Albert but it's a newer model of rod that's why it is lighter.
