    Here's a modification on the arms to increase arm articulation on Feral Rex.

    Here is the gained articulation form the elbow joint:


    ....and here with the extra [portion] of the hip joint:



    If you remove the waist filler piece (on Talon it holds the tail), you get even more (about a 75º bend when using the hip joint, too)!


    Thanks! So far I have only done the modification on Talon. Here's a quick guide to explain:

    Mastermind Creations Feral Rex - Modifying the Arm Articulation:

    There are two ways to do this: One is easy the other one's is over-complicated. I chose the second method.

    Whatever method you choose, know that you will be cutting up your toy. It's nothing extreme and it wont affect other workings of the toy, but maybe only the look of it, if you look carefully.

    The piece that houses the ab crunch can ratchet more, but the rail that it follows stops it from moving more:



    Cut plastic on both sides so that there is no plastic stopping the movement of the abs:


    The other way is to just simply use a cutter to eliminate the pegs that go into the rails:


    Why do the second method instead of first method? Because you like to do impulsive mods without taking time out to find easier ways to do it, of course! Seriously, the second method could still be useful. If you want, see if covering the rails up a bit to create friction will make the elbow joint a bit tighter. I don’t know if that will work. Just cut the pegs if you want the same extra articulation made easier.

    Here you can see that removing the waist cover lets you take full advantage of opening up the elbow articulation with the modification (you only get one extra click with the mod if you don’t remove the waist piece):


    I need to study if cutting that piece in the right places will get me more articulation while also having the part in place and still work with the tail (I think cutting up the one for Tigris will be easier).

    Just remove the screws on the crotch part and the torso part and the piece with the elbow joint can be removed:


    The ratchet itself is another story; the pin that holds the pieces is super hard. You can see I scratched that a bit trying to remove the pin in this pic (the pin can be seen below my finger):


    The piece that creates the ratchet action cannot be correctly accessed to reinforce it unless you remove the pin. It is sandwiched between the part that holds it and the dented part:


    I want to try to find a way to create friction between the rails I mention on the tutorial to see if that is an alternative for hardening the elbow joint. If it works, people could maybe get stronger elbow joint, even if they don’t want to cut Rex for extra arm articulation.

    Mine ratchet ok. I use the hip joints when posing the arms, too.
