Encouraged by my recent work on a Big Squiggoth conversion, I've bitten the bullet and invested in a War Mumak of Harad model to convert into a Gigantic Squiggoth.
Based on the dimensions I have found on another thread regarding dimensions here, and a useful youtube video also, I know the approximate dimensions for a Gigantic Squiggoth. The War Mumak of Harad is roughly the same height, but is perhaps a little less wide and less bulky, and is also a tad shorter.
My plan to rectify this is to thicken up the body by adding an inch or so down the central point and also thicken up the legs at the joints too. I am still unsure about the problem of length, but I will wait and see when the model arrives. If anything the FW model looks a bit long, so I'll decide on that issue when I inspect the Oliphant in more detail. I'd rather have a model that looks good then one with perfect dimensions.
I also like the look of the Chaos Mammoth, and believe it would be nice to make my Mumak more mammothy, while I'm at it.
Like my Big Squiggoth project, I am also planning to make the model more Snakebite Klan themed, so it will be less metallic armoured.
So that's my plan, and my project for the rest of the month. Now comes the difficult part :- waiting for the parcel to arrive.
