After loosening the pinch bolt use the red wedge to gently open up the clamp. The Kress is probably stuck in with GES (general engineering shite).

Cool will try. Was just scared the wedge would damage the assembly on the gantry because of the leverage action. Will try again.

Lol GES a technical term. One for me to memorize. Lol

GES is just one of my expressions.

Posh way is to take out the clamp screw and tap the clearance hole a size larger. You can then use a jack screw down the hole to controllably open the slot. On the other hand, I have a chunky screwdriver that has one of those red arrows painted on the tip; inserted carefully you can open the slot enough without unduly loading the gantry and the marks will be in the slot and won't show...
