I started with a pile of iron with enough mass to do what I wanted it to. Well, iron stuff, but same difference. Then I connected with the molecules of the iron with my telekinesis and hyper-accelerated them, basically melting the stuff into a big glob of molten iron. Then I just used my tk to hurl it on him and shaped it the same way. After that I just slowed the molecules of the stuff down until it cooled and solidified. If your friend was interested, I could probably do the same thing for him.
