My first homemade beyblade part due to getting fed up with lack of weight and shattering weight disks, a heavier weight disk made from 2 bits of 2mm thick mild steel and turned out well balanced considering done with a grinder and file.
As fitted to a wolborg base with Dranzer V2 attack ring, left spin gear and 2.5mm metal shaft with domed point at the end (bit of a random bitser really)
Started making a 3mm thick aluminium Dragoon G attack ring to see if i could do something a bit more intricate and it be balanced ok, it was a bit rough and could come loose against an opposite spin blade and make it lose balance easy but turned out a success although not yet able to hold a bit chip
the two combined work well against normal plastics, happily pulls attack rings off reverse spinning blades.
next thinking of moving onto more metal parts, getting them laser cut in steel so they are more realistic to the original anime series and have better spin times but are more interchangeablelike being able to flip attack rings so they can be used in left or right spin
