Next where going to get another pen with a rubber grip on it.   Preferably one about the same size of the pen we are turning into our vacuum pen

Cut a swatch out of the pen grip about as long as your alligator clip and wider than it.  On mine I had to cut a couple extra swatches to pad the clip so that the rubber flap sat flush on the nose cone when the clip was closed.
