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. 

 

Well thanks m8. I dint know if I could ask in radicons, thought it was only for customs.

 

Either general discussion or tutorials are great to ask in

REDLINE or Plowking are 2 of the best for advise(among plenty of others).

 

also, go to frenzyrumble.com

there's a tutorial there for specifically that kind of thing.

 

Any kind of modifications you want to make are a form of customising.
