Answers.Body: <p>Although it can be done (I will share below), I would sincerely discoure you from gluing your LEGO sets. You will very much regret it later.

  <p>LEGO has generational value. Your son may have lost interest now (very common in teen years), but may want to get back to the hobby later. He will definitely regret gluing his sets. Also, even if he doesn't get back to the hobby, if he will decide to have kids in the future, they will greatly appreciate having the opportunity to play and build with LEGO. Many LEGO fans inharited their LEGO sets from their parents and even grandparents. The long-term value of LEGO is truly amazing.</p>
  
  <p>And this brings up the third point against gluing LEGO. The sets you mention have significant value that will only rise when the sets get retired. If your family ever gets into financial trouble and need to get some cash quickly, you can sell those LEGO sets - but not if they are glued.</p>
  
  <p>I would encourage you to consider just boxing the sets (either built or taken apart) and just store them away carefully. It is really your best option that would keep both the value and the usefulness of the sets.</p>
  
  <p>Having said that; if you still want to glue the sets, yes, you will need to take them apart and glue them. The most gentle glue that would not damage the LEGO elements too much but will hold the model together is simple white school-glue. You only need to add very little in between elements so the glue doesn't come out at the edges.</p>
  
  <p>Another option is to just wrap the whole set in thin plastic sheet (the kind used for wrapping food). This is more for storage and moving the set around, but the tight-fitting plastic prevents the set from falling apart. </p>

Answers.Text: Both myself and others have listed options for gluing and similar methods. I added reasons not to glue LEGO, because OP may have not considered them, and so many people regret the decision later. If OP truly didn't care, he/she would have probably mentioned that in the original question. It's better to be safe and provide additional information, then omit important considerations that OP might find helpful in weighting the pros and cons of their decision. However I do agree that I could have listed the options in a different order for a better answer. I will keep that in mind for the future.

Answers.Body: <p>Use MEK (Methyl ethyl ketone). Can buy it in hardware or auto body shop supplies. In auto body work it is used to degrease and clean adhesives off surfaces. It is also a major component of ABS plastic cement, which you can also use but it's messier. You can also put a bit of MEK in a glass jar and then throw in old lego pieces to create a filler and cementer. But that is a rare thing to need.</p>
  
  <p>I use an eye dropper bottle (glass of course) or glass syringe to glue parts together. You MUST be in a well ventilated area, and I mean well ventilated. 
  MEK melts plastic so put the pieces together before it evaporates. If your eyes are near MEK they will be bloodshot, so have a fan or do this outside, like I do. Also wear those cool blue non latex gloves to protect your hands. </p>
  
  <p>I use MEK to glue major structures together that fall apart - like supports. In tall structures I will glue the structure into two halves so that they can be stored partially unassembled, and then put back together. It is also useful to glue things like space shuttle parts that continually fall off when played with. I never glue all of the pieces, just the major parts that support the toy, that way it can still be disassembled. </p>
  
  <p>MEK works great and I love how it keeps builds together that would otherwise be lost forever in masses of parts stored in bins and tubs. </p>

Comments.Text: @Acleverlegochild One of the key lessons in Lego for children is _scarcity_. Sometimes you have to make do with the pieces you have; this forces kids to come up with novel solutions to problems. Thus I'd recommend not buying more and more lego unless your kid's work is truly genius. Most people just take lots of pictures and post them on Flickr.
