LEGO 4-Juniors minifig customization

by admin on February 12, 2011

in LEGO Modification

Between 2001 and 2004 LEGO released a line of “juniorized” sets called LEGO 4-Juniors. These were aimed at kids who grew out of DUPLO, but may not be ready for regular size LEGO. The sets were simple to build, and included 2-inch tall minifigures – easier to handle for smaller hands, than regular LEGO minifigures.

A lot of enthusiastic LEGO fans have a dislike of the LEGO 4-Juniors line, thinking of them as too childish, however there are some cool sets and parts in this series. And in my opinion there is no such thing as useless LEGO. ;)

I particularly like the LEGO 4-Juniors figures (also called Jack Stone figures). They have interesting features not available on regular LEGO figs. Also, they are extremely cheap on Bricklink, Amazon and eBay! (Click on any of the links to take you to relevant listings.) Most sellers just want to get rid of them, so we can use this to our advantage! :D

However because the figures are larger than regular minifigs, it requires some imagination to incorporate them into a regular fig-scale MOC, but it can be done! As an example, here is JasBrick’s conversion of a LEGO 4-Junior’s figure to Avatar’s Jake. I love this fig!

Also, because the LEGO 4-Juniors figs’ head is the same size as regular minifig heads (except they have cute little nosies – sorry I just had to say that!) with a little modification their heads fit quite nicely on regular minifigure torsos. Once the modification is done you will see how nicely they blend in, and ad some variety to your minifig collection.

This modification is not for the faint of heart, as we will have to cut off the LEGO 4-Juniors fig’s head. But other than that, it is quite an easy process. (You can click on any of the pictures for a larger view of the procedure.) If it helps, just remember that we are going to resurrect the little guy into a new body. ;)

(Before attempting to perform this “operation” on your LEGO 4-Juniors figures please read our Tutorials Disclaimer for your safety.)

THE PROCESS:

1. Choose a LEGO 4-Juniors figure that has the facial features you like. Here is a list of all the LEGO 4-Juniors figures: LEGO 4-Juniors Figures

Please note there are 2 types of LEGO 4-Juniors figures; some of them have more angular facial features, and some have more rounded heads. I personally prefer the rounded head version, because they are more like regular LEGO minifig heads. However I will show you a modified angular-face minifigure as well, so you get an idea how it looks after being modified.

2. Use an X-ACTO knife, or other hobby-knife to cut off the LEGO 4-Juniors figure’s head. Try to make the cut close to the torso, leaving as much of the neck attached as possible.

3. You will see a stem inside the neck, going all the way up into the head. Use your knife (small, sharp scissors also work) to remove as much of the this as possible. (This is probably the hardest part of the process. I just insert my knife into the neck-hole and chop and scrape the stem, until it is no longer in the way.) 

4. Use a file or sandpaper to start sanding down the neck to the right length. (I usually sand the neck down to the same neck-size as regular LEGO heads.)

Make sure you are filing the neck down in the correct angle. Otherwise the head won’t sit straight on the torso.

5. Start enlarging the neck hole. You can use various tools for this. I just insert my small scissors (it has a sharp outer edge) and keep rotating it inside the hole, shaving off the access plastic, until it reaches the correct size. I check from time to time to see if it fits on the torso – if not I continue enlarging the hole.

6. Attach the modified head to a regular minifig body, and there you have it – a cute minifig!

What to do with the rest of the LEGO 4-Juniors fig’s body? In case you are wondering; here is how the rest of the LEGO 4-Juniors figure’s body looks disassembled:

If you are into customizing, I’m sure you will come up with something for the rest of the LEGO 4-Juniors figure’s body parts. I personally like their boots, so I cut them off and line them up in a shoe-rack for my LEGO houses.

Just attach the head to a torso and wiggle it out. If you still have trouble, you can do it under soapy water. ;)

These are just great! I’m going to dig out my crappy Jack Stone figs right now!

Yeah, I love the Juniors heads! I have converted many more since this tutorial was written. They are really cute and blend in well with regular LEGO figs. The only difference is the little nose (which is cute) and the awesome hair/hat styles. The pirates are particularly great! :D

They are not cheep anymore!!! Look on Amazon. (Maybe that’s just the new ones though!!!)

Look on eBay or Bricklink. They are the most unappreciated figures. Amazon is not a good place to buy discontinued LEGO as they are from private sellers and the prices are too high. But eBay and Bricklink are your friend – at least in regards to Juniors figs. Everyone just wants to get rid of them. ;)

Nace, that’s all right. If you like them as they are, just keep them. ;)

Admin may you please change all my comments Gravitars to my normal one??? My sister made a Gravitar and it screwed up my comments.

Reply

admin June 12, 2012 at 9:15 PM

Oh! I see what you mean! Unfortunately I can’t do it. Your gravatar is tied to the email address being used. If it would be a couple of comments messed up I could do it manually, but you have like like 60 comments with that email address! The only thing I could suggest is that you create a separate email address for her, so she can make her own avatar, and you put your avatar back on that email address so they will automatically change back. :(

I wonder if anyone have tried customizing the McDonalds sports figures to salvage their heads/ helmets. They looked Lego-like but they had a pretty non–modular format and were basically only compatible among themselves.

Hakan, I have been actually thinking about giving that a try. ;)

Would this work with duplo figs?

Reply

Håkan February 25, 2014 at 9:59 AM

I’m not quite sure about what you are referring to, but even when disassembled, Duplo figs probably wouldn’t be very compatible with minifigs, since all the connections seem to be twice the size.

According to this site, it’s possible to disassemble and customize your own Duplo figs by combining parts between different figs.

(I accept no responsibility for any users choosing to follow this advice. In any case, be patient, and keep a steady hand.)

Those who are crafty can reconfigure your own minfigs. All you need is a metal pin or smooth side of a drill bit to push out the hip pin in your minfig. Once removed, everything comes apart easily, except the head. Use a set of needle nose pliers to close the inside of the neck and the head and hair/hat will separate from the torso and each other. You can now reconfigure as you like.

If you are disassembling a lot of minifigs, you will want to special built tool for this process. You can make a very simple tool from a large C-clamp, a proper sized Hex Bit, a small 1/4 socket and two part molding epoxy. epoxy the Hex bit on the static side of the C-clamp so that it point to the centerline of the moving end of the C-clamp. Epoxy on the 1/4″ socket so the hole will center around the axle pin on your minifig. Let it harden and this should allow you to press out the hinge pin with a few twists.
