Hi Dan,
As you have a QCTP, have you considered the parting blade holders sold for it? I have the BXA size, which takes a 1/8 x 5/8 x 4" HSS blade, or for really hard stuff I have an insertable carbide blade in its own holder which in turn goes in the tool slot in a QC holder (like this: http://www.warco.co.uk/parting-off-tools...blade.html - only slightly posher: sideways-T shaped with a tongue to go in the tool slot) - I do fret that having three separate clamping points (QCTP dovetail, QC holder slot, blade location) lessens the rigidity, but no problems so far apart from the inherent brittleness of the carbide inserts - they don't like interrupted parting cuts, for instance!
