Thanks to everyone for the advice on vacuum clamping. I have also been searching the Internet and have found some information.
Gerry, I have been a subscriber of Shopnotes for about 3 years now. I have that issue and forgot about it!!!
This site has some vacuum plates that they sell. I like the way they use the vacuum tape on plastic plate. Just make one ¼” hole and with creative use of the vacuum tape you can open gates or close them to fit your work size.
