set 7258 cant find a pic, but in my mania magazine catalog, has something called "wookie attack" one of the "ships" looks like a snail, with a fair amount of that somewhat rare lego technic tread. Chris (20 years ago, 19-Mar-05, to lugnet.org.ca.rtltoronto)

(...) The problem with this method is it applies uneven force to the object through the fingers while they are closing. So if you have two fingers and one hits the object first it will have to apply enough pressure to the object to over come the (...) (20 years ago, 18-Mar-05, to lugnet.org.ca.rtltoronto)

(...) I imagine it could be done with 2 standard diffs - one output of diff1 drives the input of diff2, the other output of diff1 & the 2 outputs of diff2 drive the fingers. You may have to experiment a little with gearing to get it right. Of course (...) (20 years ago, 18-Mar-05, to lugnet.org.ca.rtltoronto)
