Recently, I had to prox special weapons again. This made me sort all my CSM, take stock and get two boxes of regular chaos marines to assemble with special and heavy weapons. I had ordered two autocannon kits previously, and will focus on adapting those to the plastic csm kit.
The magazine backpack attachment does not fit the CSM backpack at all,
obviously the mag is meant to fit snugly on a 30k backpack. In
particular the CSM backpack is thicker in the lower area and this
results in the mag's rear not being in line with the backpack's rear by
about 2mm, which again results in thr ammo belt ending up in the wrong
position relative to the models arms and weapon.
After some trials, I settled on clipping the tailpipes off the CSM backpack and flattening the area between them by trimming it down with the hobby knife. In addition, I took a chisel hobby knife blade to the inside of the mag and cut the two tabs on the top at about half thickness.
This results in the parts fitting into the right position,
but without good contact for gluing. I superglued a small ball of green
stuff into the mag, coated the backpack with superglue and pressed it
into the mag. As the green stuff sets, it will be slightly flexible but
hold the parts in place.
I'm quite happy with the result! :)
