anybody know where I can get a custom mixmaster for a devastator or some tips on making one without making it a parts former,im tryin to build one without using lego joints to connect the arms by using some base weapon thing from some green heilcoptor transformer(i don't it's name)but the base has arms so I cut it in 3 parts and they fit real nice on the base plate over long haul but it makes it uneven cuz they set under hook should I try mounting it on hook?
