In fact, it is not generally possible to make.
I used a broken axle to make a 3.5 length axle and use it as his neck.
If you use metru head and raise ball socket on his neck by one stud, you can make it without broken axle
How did you break a half-unit off of an axle? I’d just cut it.
Really like this, especially that shoulder design, it’s one of my favorites, since I don’t have a lot of standalone balljoints for custom torsos. The weapon seems a bit large as well, but otherwise this is a great MOC. It reminds me of a set, while still being mostly custom.
