I picked up special 4 jaw chuck yesterday for the 102. It is a Roehm EG series which is a 4 jaw scroll chuck that also has independant jaws if that makes any sense. Bit expensive but should prove to be useful. The design is interesting, basically it looks like a normal scroll chuck with adjustable jaws stacked on top. I had heard of these but never seen one before. It had never been used (still in the box) but had been sitting for long enough to harden all the grease so I had to disassemble, clean and re-grease etc.
