So does anyone have any tips on how to pin a warhoud?
I don't have much experience pinning anything

but I understand you need a power drill and 2mm brass rods instead of just the
GW drill and paperclips.
I assume I'll need to pin the ball joints at the ankles/hips/elbows/neck and I've seen someone pin the with a nice big rod at the waist which can be taken out to disassemble it for transport.
As for the body:
1. seems pretty simple, pin the engines onto the.. controly-part?, from there use the engines to pin the front half of the body on (2.).
I have no idea how to pin the shoulder/part with the servitor but since they are going to take the weight of the guns I assume it's necessary, should that be done with paperclips?
*One more thing, looking at the head the head side looks easy enough to pin but I can't see much room on the body side to stick a pin without drilling through into the inside
