Not long ago I discovered, in his home workshop old Microdrive MK-12-In, preserved, apparently, since childhood. What to do with it? Throw a pity, and here decided though somehow to use.
In fact, from the Microdrive, I left only the cylinder with the body. Flange, lug, slide and roller are machined in the cabin DIY. The rest was done in a vise with a file and hacksaw. As the axes of the pins and needles from the needle bearing. The handle was made of textolite, conveniently placed switch. Used motor PL-062 capacity of 150 watts.
