I take some pride in the fact that, way back in 2005 or something, I drew up plans for this thing on graph paper and for the most part, I think what I drew in those plans back then holds up. I think I nailed it. That said, from time to time a detail does come up where I think it benefits from a bit of revision. Sometimes this realization comes long after I&#8217;ve built physical model parts for that portion of the design. The forearms are one such area: In principle the forearms on the Zaku Kai are pretty simple, but in practice I find it a bit difficult to execute that design in a way I&#8217;m really happy with.<br \/>\n<a href=\"model-data\/1_100_Zaku_Kai\/zakufz_20220216_forearm_overview.jpeg\"><img decoding=\"async\" src=\"model-data\/1_100_Zaku_Kai\/zakufz_20220216_forearm_overview_thumb.jpeg\" title=\"Comparison of the current forearm from my Blender model of the Zaku Kai with the scratch-built parts I made in 2012 or so\"><\/a> <a href=\"model-data\/1_100_Zaku_Kai\/zakufz_20220216_forearm_overview_2.jpeg\"><img decoding=\"async\" src=\"model-data\/1_100_Zaku_Kai\/zakufz_20220216_forearm_overview_2_thumb.jpeg\" title=\"A 3D printed copy of the forearm vs. the modified scratch built part\"><\/a> <a href=\"model-data\/1_100_Zaku_Kai\/zakufz_20220216_forearm_adjustment.jpeg\"><img decoding=\"async\" src=\"model-data\/1_100_Zaku_Kai\/zakufz_20220216_forearm_adjustment_thumb.jpeg\" title=\"The modified scratchbuilt forearm part\"><\/a><br \/>\n<!--more--><br \/>\nThe forearm is basically built out of three components: There&#8217;s the roughly cylindrical core with thicker bands at the wrist and elbow, the knobs on either side of the elbow, and &#8220;vambrace&#8221; that covers the back of the arm and extends over the elbow. When I originally designed it, the core part was straight, built around a single axis; something you could turn on a lathe, basically. Over time I started to feel my interpretation of the forearm didn&#8217;t really look as nice as I&#8217;d like, but it took me some time to work out how to improve it. Generally I felt that giving it a little more of a curve and more of a sense of bulk would help, but it&#8217;s hard sometimes to get from a broad idea of what I think will be better, to an actual choice that I believe really is better. Eventually I came up with a nice improvement for the part and incorporated it into my Blender model.<br \/>\nHowever, these changes hadn&#8217;t previously made their way to the parts I&#8217;d built back in 2012 or something. I&#8217;d considered it but never took the plunge to actually make it happen. As it is I&#8217;m not sure it&#8217;s quite right, I&#8217;ve introduced more of a curve to the forearm but I&#8217;m not sure the bends are just in the direction they should be. I&#8217;ll keep working with them to clean up the spots where I cut the part, and to correct the bends if I decide they&#8217;re not good enough.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>This project has a long history.
