Magnetic vise soft jaws

Thanks. Nice job.
I made some way less eloquent magnetic jaws, then used them to hold a piece I was silver soldering. The heat killed the magnets and I had no easy way to remove them. Ended up drilling a hole from the face side to the magnets so I could punch out them out.
Would you consider making that hole before pressing the magnets in or do you just plan not doing anything stupid that would ruin the magnets?
