A method being used by many for thin stock with some success is to fly cut a backer plate, lay down painters tape. Lay painter's tape on the back of the stock, and super glue the tape together.
I decided to try a new painter's tape. Its called Frog Tape.
"What is it?"
"Its... green."
I have been using regular blue painter's tape and it is ok, but if I run flood coolant it sometimes picks up. The green Frog Tape is supposed to not allow bleeds of paint under the edge like the blue tape can sometimes. I thought, hey maybe it will work with coolant too. If its reacting with the liquid at the edge to form a seal maybe it will do the same thing with flood coolant. Water and SC520.
I make a type of part fairly often called a divider plate. Its used in minnow molds to create a hook slot. It usually has a couple holes drilled in it for placement pins or screws. In the past I've used the blue painter's tape and super glue trick. Then I'd drill the holes first, drill a hole below in the backer plate, and tap that, then shoot screws in. The screws would keep the divider plates from moving while the profile is cut.
I'm doing the same thing with 20 divider plates right now using the green Frog Tape. I left 3 plates unsecured. One at opposite edges of the sheet of stock and one in the middle. They are cut out and all three unsecured plates are still in location. Right now its doing a cleanup pass at full depth. If they are still in location I may risk just using the tape in the future when I don't have holes I can use for clamping.
Clean up pass finished will I was still typing. All plates are still secure.
