I've wanted these guys in my collection ever since the first Hobbit film, Dwarves are my favourite fantasy characters so of course Gimli has always been my favourite character in LOTR and I built him years ago, my first custom body I think. These characters have only been produced as 1/6 in polystone statue form by Weta and I believe not all of them, not cheap either!
To help me with these rather ambitious multiple builds I asked fellow member and artist Peter The Painter to do all the head sculpts because he is excellent at capturing likenesses no matter the subject, works very fast, great communications and his sculpts are one of a kind pieces of art.
So with the heads taken care of by Peter, that just leaves everything else for me to do starting with the bodies. Dwarves are shorter than humans but larger than Hobbits, they are also very stocky due to their enhanced strength so there are no readily available 1/6 bodies around to make Dwarves. I first decided to hunt down as many 'over sized' Hobbit bodies by Toy Biz for all the articulation and the correct height 8"-9" with a head, unfortunately most of the ones I found for sale were in the USA and I'm in the UK so shipping and customs charges made them monetarily impossible for me to buy 14 of them. I then thought Mego bodies but they are too short and rare, also only available in the USA (there's a company that makes reproduction Mego bodies). After a random eBay search for 9" figures/bodies I discovered the Trendmasters 9" Austin Powers figures that are very cheap and readily available in the UK with free shipping on the most part. They also have the advantage of coming with fabric clothing variants in this unique body size, the colours and fabric types will actually be quite useful for the Dwarves.
Below are some basic reference pictures of the Dwarves and Bilbo and below those, pictures of what I have so far to contribute towards the builds (I'm still waiting for three more Trendmaster bodies to arrive).
