Apart from the midriff joint work I also took some time to check and tweak the chest block. I felt that the right side of the chest was sitting a little higher than the left, and angled a little farther out. Making this kind of determination is a little difficult with an ill-defined midline (in fact you could say the error exists because I built part of the assembly with one midline, then added more work with a new midline). I feel like I&#8217;ve maybe opened a can of worms here but after adjustment I think it lines up with the backpack better, at least.<br \/>\n<a href=\"\/model-data\/1_100_Zaku_Kai\/zakufz_20220330_chest_block_adjustment_1.jpeg\"><img decoding=\"async\" src=\"\/model-data\/1_100_Zaku_Kai\/zakufz_20220330_chest_block_adjustment_1_thumb.jpeg\" title=\"The chest block as it was: the chest block's right side is a little higher than its left\"><\/a> <a href=\"\/model-data\/1_100_Zaku_Kai\/zakufz_20220330_chest_block_adjustment_2.jpeg\"><img decoding=\"async\" src=\"\/model-data\/1_100_Zaku_Kai\/zakufz_20220330_chest_block_adjustment_2_thumb.jpeg\" title=\"I had actually put a styrene shim in there to raise that side of the chest block - the result of some faulty alignment checking maybe?

Looking at it after the work, I feel like the top level and the angle of the chest block are better, but lowering it made the chest blocks forward edge and lower edge, and the detail I added to the upper surface recently all noticeably lower than the other side.
