With a big model like the all metal Grenadier Death Giant of the Undead Legion, strong support is needed to hold those parts up. I had arranged a decent pin for the upright axe-wielding arm, but I felt more was necessary and so added another pin.
There was no more room in the arm cast to drill another deep hole. Half of the cast was now occupied by a failed attempt: a snapped drill bit embedded in the metal. I had enough to seat a pin comfortable, but the corresponding hole would have to be on the torso.
To do this, I had to build up an area of Green Stuff, let it cure, then drill into that.
A brass pin was seated into the arm casting,
The two pins participate nicely, one being rooted in the torso casting (old steel) and one being rooted in the arm casting (brass),
The fit works well, and the two pins being (of course) ever so slightly not parallel actually makes for a nice tight grip, even without glue.
But an unsightly gap needs some filling and detailing with more Green Stuff. I'll share the progress soon. Thanks again for tuning in to this blog!

Death Giant Left Arm: Joining Two Heavy Castings
In 2003 or so I had installed a pin to hold the left arm of the Death Giant, a corresponding hole was drilled into the shoulder of the arm casting, but on closer review I ascertained that there wasn't enough metal at that point on the arm casting to hold the arm in place with confidence.
The new goal was to increase the strength of the shoulder joint to hold the weight of the arm casting (which is quite hefty as it includes the shield as well).
I installed a new second pin, a rather thick brass post, a bit lower than the original. This creates a strong gusset to hold up the arm.
This was NOT drilled through the arm all the way, using the technique I've recently posted. I wanted enough material to rest on top of the brass post, so the arm was only drilled half-way.
It's rather ugly now and betrays its presence, but I'll come up with some Green Stuff additions, some torn fabric and detritus, to mask it on the finished model.
The important thing is that it makes the joint between two heavy castings very strong.
Next step will be to 'blend' the two parts together by creating more mail armor and a bit of necklace chain. I'll also share the connection of the ribcage.
