Hi everyone, this might be a terrible place to ask this particular question since it’s pretty build-mechanic related, but I also figure a great deal of us that peruse this sub may also own this (21348) set.
Has anyone had a terrible time getting the lower jaw of the dragon to have any remote sort of stability? I’m no stranger to putty/glue, we use it in a lot of our mech mocs, but I’ve never ever had to consider it with a Lego engineered set.
Am I missing something? I think putty will get me where I need to be, but I’ve never encountered it with officially instructioned Lego sets.

There are a number simple mod to greatly improve the dragon. The most annoying bit is def the jaw. The easy fix is to: replace the orange t bar with a black bar Remove orange triangle below jaw Stick a mechanical claw part in jaw and attach to bar https://www.bricklink.com/v2/catalog/catalogitem.page?P=48729b&idColor=11#T=C&C=11 You lose jaw mobility but it's worlds more stable. If you want something nicer looking but more complex there are tons of mocs out there, but I was personally happy with a few small qol mods
Fantastic, thank you!!
Saving this post for this reply
There are some fixes on Rebrickable, too
Yeah ,overall the dragon is not well built. Especially the head and jaw
On gunpla comunity a common tips to tighten joints is to apply a layer of topcoat/paint
I wonder if this works well with Lego ball joints? If I have no desire to alter the color does one just apply some sort of clear coat or translucent paint? I’m clueless in regards to paint.
Not really applicable to this as much, but would solve a lot of my problems elsewhere if I can get it to work for the larger ball/socket joints.
Thank you for the tip/help
There's several kinds of topcoat : some more satin some more mat.
Jesus.
I’m going to do my best to ignore the rampant talk of glue and putty in this thread and just stick my nose in here to mention that a purist solution to loose ball joints is to take a piece of instructions/adverts/sticker paper that comes in a set and put it in the ball joint.
This is what I currently do in these situations, though I use a very thin layer of bluetac/putty rather than the paper/vinyl.
I get the heresy/sacrilege here, but at least 3 of our very large mechs wouldn’t be playable on the table without it. We can display everything very easily, but these models are used in a tabletop wargaming system (entirely in Lego) and they need to be “table worthy” in the sense that they can be repeatedly moved/adjusted/carried. That’s where the hard part comes in, at least for our family!
For me, the first ball joint of the tail is the problem, the one connecting the tail to the body. After moving it a could of times, lots a lot of its grip
I commited a lego sin. And put a little glue on the stud that connects to the claw that is the hinge. I did not glue them together. But made the stud thicker. Now it stays on
I’ve not personally had joint issues with Cinderhowl, though the tail was definitely a little more back heavy
You probably got this already, but the jaw connection is horrible dude. I really wish they could have done something better. There were so many options.
