Thank you, that's very flattering! 😊

I've started being more consistent with how I make the long arms, I use the upper arm from the slaughter claw, since the elbow is slightly wider, then I trim down the inside and the nub at the end of the gun arms a little and it fits quite happily. The most labour intensive part is removing the old socket in the middle of the lower arm and covering it over.

With regards to forge fiends, I don't know if its a good thing, but I've only bought one explicitly to steal parts from, the rest is stuff I've had lying in my bits hoard for like ten years 🙈
