2007-01-30 jaw simulations – doyle rev 1/30/07 2/5 Alternative Jaws Baseline: Glidcop + Mo shaft Glidcop with Glidcop shaft In case of fabrication problems with Mo Glidcop with Cu shaft If shaft/mandrel can be made one piece .5 m long Glidcop with Mo shaft Lighter, stiffer, more stable, etc 2007-01-30 jaw simulations – doyle rev 1/30/07 2/5
