Hi there
For those of us that read and droolled on the Horus Heresy artbooks, that wanted to build an Adeptus Custodes army, But can't scuplt even a snowman with GS; Here's How I did mine.
I must warn you though You should have a Huge bits box (or bank account) ...
1: what you need

1 plastic marine commander's cape
2 Dark Angel veteran legs
3 Space marine arms (chaos or loyalist it won't matter)
4 High elf spears ( most of the time you'll only need one but you know)
5 Winged Skull Icon from the HQ marine squad
6 Winged Icon from the HighElves Spearmen
7 hands from the Chaos warriors
8 Marine shoulder pads
9 spiky bits from the chaos warrios
10 a bolter
11 Chaos marine back pack
12 A Tomb Kings Sword ( can get it with either the squelettons of chariots)
13 A High Elves Silver Helms head
14 This Chaos marime helmet ( to get the plumet)
not show the front of a marine torso ( the MK8 plate aldeardy has the collar but any thing can do)
2: What you can also use


These capes are from the Empire Plastic general and High Elves archers
These Heads are from the High elves Spearmen and Chariot (the chariot ones already have the plumet) but remember both are abit smaller .
The legs can also be replaced with regular or chaos marine legs
You can also use Dark Elves spearmen spears
For the marines shoulder pads..... just use what you can get your hands on
3: Let's play

Cut out the back of the torso from The DA legs and glue the cape and front torso together

The tricky part is the hands and spear .... start with gathering what you'll need then cut out the forearms and hands and the weapons from the Chaos warriors hands(7) . Then cut a part of the spear ( approx 1,5 cm)

If you don't want your Custodian to fall into pieces each time you touch it ( belive me it really happens) Drill the hands through and use whatever thin metal rod you can get. You'll also have to drill the middle spear bits on 2mm each side
Then cut the right arm just under the shouder ( he ain't be holding a bolter )

Now you'll have to position everything and see how this gets together
you'll need several attemps before getting a satisfying result

Once you'll get the above stated satisfying result glue the hands and middle spear on ( again think drilling ....)
And glue the legs too you'll see what the general pose of the figure will be .

Now cut 2 other bits of the spear
IMO the lenght of the High Elves spear is quite good you can use that to make sure your Custodians have the same lenghted spear

Glue the bolter on the spear, Then the Tomb Kings blade (12 ) and the chaos spiky bit (9) on the bolter.
And glue the pads on. Take the winged skull icon (5) cut out one wing and glue it on the right shoulderpad, (5) (note you might have to dremmel it a bit inside to make it fit well))
Now if oyu didn't use a Mk8 Front plate ( just like here) you might wanna add a collar ( it will hide the flesh part of the Silver Helm head...):
A small bit of plasticard 1cm long and 2 or 3mm high that you'll glue on....

Now glue the Silver Helm Head (13) on which you'll glue the chaos marine plumet (14)


We're almost there, the back pack
You cut the High Elves winged Icon (6)in 2 ( cut out the gem) and glue them on the Chaos marine back pack (11)

Glue the backpack on , a base, Et voilą !
It might seem long and tricky (sometimes boring even) but when you love....
