It's difficult to tell exactly what part this fragment came from, but it looks like it is part of a broken Technic gear or pulley. It looks like it probably came from 3736: Your fragment looks like it was probably once one half of the center axle hole of that part. In terms of repair, I suppose you could try to glue this back together, but given that it ...

Lego is very good about replacing broken parts - for free even. Visit the web-site and look on the bottom of the page under Customer Service for a "broken or missing parts" link (I can't check at current locale).

Brasso (yes, the metal polish) works better than toothpaste in this case. It is a bit more grainy so works faster but doesn't damage the parts. It does take some work though that may or may not make sense depending on the rarity of the elements. And yes, with either toothpaste or Brasso, you actually have to vigorously rub the surface to buff it up. It ...

Oh, those look sad! Stickers with white designs on them are notorious for peeling/cracking. I have found that the best way to protect stickers like these is to apply a thin layer of clearcoat to them while they are still new. Wait until the clearcoat dries, then apply the sticker to the LEGO set. You can use pretty much any acrylic clearcoat, medium or ...

I had this trouble when I was a nipper. My dad owned a model shop so I used the same glue that you use on Airfix type kits ("Polystyrene cement") - you can get this from model shops. Use a cocktail stick to smear a bit inside the figure, above where the top nobules of the legs will go so it won't interfere. Don't use too much because it kind of melts the ...

You won't be able to make it fit perfectly again. If plastic is stretched over a certain point it is irreversibly damaged. But you can try to heat it a little to shrink the wheel overall. But it's not guaranteed to work. If you use a lighter you can affect a smaller area but be sure not to burn your part.

What I have found that works, most of the time, is DURO super glue. Extreme safety must be exercised as it is super glue and can cause skin to bond and burn as well as prove poisonous via inhalation. I would recommend using wet(with water) latex cleaning gloves as the water seems to prevent the gloves from sticking to themselves or each other to handle the ...

This means your NXT is spoiled and needs reseting. This is usally caused by unplugging before the program downloaded. To reset 1) Completely disconnect your NXT from the computer (no USB connection). 2) Remove all external BlueTooth dongles from your computer, and turn BlueTooth off on the computer (just to be sure). 3) Reboot the computer (this is to ...

You can replace the arm with a new one by carefully removing the old arm and snapping in a newer one. Please note that this should not be done too often, as the procedure will damage the connection and could even crack the torso. LEGO never attempted the arms to be replaceable. It is not like snapping and unstapping bricks, however it can be done a couple ...

As someone already mentioned, I doubt there's any way to make it fit "perfectly" again but it may be possible to reduce the damage. Another way to apply heat is to use hot water. As for how hot, I've got no clue what temperature that particular material starts to soften at, but I'd start out with the hottest water you can get from the tap and increase the ...
