Posing the ragdolls took up most of the time because I couldn't get the headbands lined up on their heads. And I couldn't weld them together after I positioned them because the head hitbox was significantly larger than the headband.
Also, a little-known trick is that if you already have the stuff nocollided and you're only going to be using Weld for it, if you click one thing with Weld, switch to the physgun or whatever, position shit, etc, then switch back to the Toolgun, it'll still have the first thing you clicked as welded object #1.
I.E. Weld on head, switch to physgun, position headband, switch back to toolgun, weld on headband.
I'd get back into Gmodding but my Super DoF is still borked.
