I was thinking of combining my upper torso Gandalf the Grey (Blue Sword Sheath) with the lower torso of the Balrog Battle Gandalf - as that one has the ankle articulation I want, but I prefer the head and upper torso of the Blue sword sheath Gandalf.

I've not done any sort of modding before, do you think it could work? What's the best thing to do? Just heat it up with a hair dryer and try and separate each section of both figures and try snapping the wanted sections together? Would they have the same waist peg?

Really appreciate any and all help! Thanks!

With swapping joints I tend to bathe a figure in boiled water (usually use a big china cup and put hot water boiled from a tea kettle in then put figure in. For Leg swap I'd saw the waist swivel on both figures then sand so its smooth then glue the other persons waist onto the swivel. Hard to explain without illustrations. If I get the time I will make a new tutorial but I don't know if I have any projects that require that at the moment. (Essentially the pelvis part of the Blue Gandalf is a T shape with forward backwards motion legs. You want to keep the upper part of the T so the T becomes like - this way you have the swivel joint attached from the torso and can stick a donated T part below. This also allows you to chose either lower robe part).

I completely agree with your comments about his upper articulation, its great! And again, on his lower articulation, its a shame it has no ankle movement and wonky hips. Do you have a tutorial about how you did your Gandalf mod? Or know of a helpful URL on how to mod the LOTR toybiz line? I'm hoping to mod my Gandalf figure.

It depends how you want your Gandalf to work. I used the Balrog battle one as a base as I like how the sleeves are rubber and there’s a joint there. I’d suggest looking at my “The Fellowship of the Ring” post I did for reference but essentially it’s Balrog Gandalf with a better gandalf likeness head. Yohcould look at my Martin Septim or Manimarco customs for robe/ sleeve sculpting/ articulation as you can get double joints with a sleeve end piece. I could go back and customise my Gandalf further makinf his sleeve more solid and the articulation better but I’m fine with how he is. Hope this helps, feel free to message me if need help!
