One of my latest projects is an Imperial Knight. I was requested to try and magnetize the right arm weapons, so that either weapon option could be used. This was a little tricky since both weapon options use a few of the same parts (the main body of the gun). But with a little fiddling I came up with a solution.
Here are a few pictures of the parts both attached and unattached.
And last up we have a preview of the painting! The main red color was painted as follows:
Basecoat Mephiston Red, Shade with Agrax Earthshade, Highlight with thinned Blood Red. A wider, thinned layer at first, and then a narrower second layer near the edge can be an effective, quicker way to blend the highlights, rather than having to mix a mid-tone.
