Soon to be extinct

Got the two parts welded up and moving about properly, but again hit a wall with power. I have several motors about, but none seems perfect for the job of powering the jack head. I went on a more wide ranging search for geared motors in the evening. In the end an auction site showed me some window winder motors advertised at 1450 yen each. They looked like just what I wanted, but I figured on begging for some first. I had already thought of car bits as ideal due to their 12 volt diet.
