i liked the idea of LEGO's new Iron Man UCS Hulkbuster set. however i couldnt justify $130 for something i needed to almost completely change. so i purchased the LEPIN knock off. i then used about 500 of my LEGO bricks to fix it into something a bit better looking.
to modify your own jackhammer arm, start by making it longer along with a longer technic pin this will allow for a larger punch!
