Help holding this material down!

Thanks guys!

Barry, I did the through cut last, but still need to run the chamfer operation on the perimeter. I am hoping that an 1/8" endmill for the cutout might help not let as much vacuum through…

Mike, the Grady White sounds like a cool project. You must be on fresh water, I am a Merc tech and I’ve never seen a Ford 302 mercruiser still running here in the salt! Restoring an old boat with good bones is super gratifying. Last year I finished a restoration on an old beat up 1980 31’ lobster boat (Pic below). 2 years of nights and weekends but totally worth it. I’m actually out on a mooring in it for the weekend so I can’t try any of these suggestions until Monday! The wasteboard holes I was attempting to keep as they are the holes that I use for cam clamps and whatnot. (3/4 copper tubing as stops and centers of clamps). I may have to take your suggestion and make a separate top or something for the vacuum table.

Tim, the foam material I am cutting is really cool. I believe it is softer than hydroturf (which I think I remember being a rubber type of mat?). A lot of people are using the seadek now, super comfortable to walk on barefoot and it usually gets engraved to look like faux teak and Holly. I will check out the seklema and engravers tape on Monday.
