No shaky hands yet for me, at least that's what I tell myself. When the shaking starts I normally lay the part I'm detailing on the work bench and lay lead weights on the part to hold it steady. Then, I lay my left hand on the work bench and hold my right hand to steady it. Seems to work pretty good but it takes a lot of re-positioning. I don't get this to often and I sometike just wait til it passes.
