Well I want to add ball joints to classics megatrons hands so I can get the propper cannon rotation thingy. How can you basicly go about digging out the plastic and such to make a ball jont go on.
Doing something like that takes skill and patience.The only way i can see how would be to mould or cut the plastic.A dremmel or heat would be easiest. you may want to ask in radicons for better advice.
Either general discussion or tutorials are great to ask in http://www.tfw2005.com/radicons-customs/general-discussion-10/ REDLINE or Plowking are 2 of the best for advise(among plenty of others).
