Custom Longboard using a vacuum bag // How-To

Check out how I made a laminated longboard for my wife using a vacuum bag and a wetdry vac!\rbrSubscribe to my channel: \rbr\rbrBe sure to check out the X-Carve 3d carving machine from Inventables!\rbr\rbr\rbrMORE PROJECTS, POSTS AND EVENTS\rbr\rbr\rbrHERES WHAT YOULL NEED:\rbr - Wood glue\rbr - Cutting mat\rbr - Table Saw\rbr - Spray Lacquer\rbr - Super 77 spray adhesive\rbr - Silhouette Portait (vinyl cutter)\rbr - TruckWheel combo\rbr - Grip tape\rbr - Thin Air press bag\rbr - Veneer pack\rbr - MeshCam\rbr - 123d Design\rbr\rbrWant to support ILTMS?

This helps make sure the valve doesnt get blocked before the vacuum is complete.\rbrThe end of the bag was sealed up with some very sticky black gluetape.\rbrThe shopvac hose fits over the valve, and when turned on, it pulls out almost all of the air.\rbrI switched over to the included hand pump to pull out the last bits of air.\rbrAfter it dried for 8 hours, I pressed the valve to release the vacuum.\rbr\rbrNext, I flipped the paper over and traced the shape to the other side.\rbrThis gave me a complete, symmetrical template to use.\rbrI drew a center line and added a light coat of spray adhesive to the blank.\rbrI added the template by lining up the crease with the center line.\rbrThen the other side laid over into place as well.\rbrI used a bandsaw to cut out the shape, but you could also use a jigsaw.\rbrI smoothed out my bandsaw cuts with a belt sander.\rbrI used an orbital sander to give the edges a very slight round over.\rbrSince I used a light coat of spray adhesive, the  template pulled off easily.\rbrI lined up the trucks, and used a straight edge to make sure they were lined up with each other, then marked the holes for each.\rbrI added a block underneath to prevent blowout, then drilled all eight holes.\rbrI assembled the wheels and trucks, which is extremely simple.\rbrI cut out some graphics on my vinyl cutter to use on the bottom of the board.\rbrAfter peeling away the extra, I added a sheet of transfer paper over the remaining vinyl.\rbrThen using a utility knife, I cut the individual stickers out.\rbrI peeled off the backing from the vinyl, which leaves it attached to the transfer paper.\rbrThen I masked off the areas along that border with blue tape.\rbrI put down a few coats of black spray paint in the exposed areas.\rbrAfter drying, I removed the tape.\rbrThe bottom surface was protected with a couple of coats of spray lacquer.\rbrI got some red grip tape. I peeled off the backing and rolled it over the top surface, making sure not to let bubbles form underneath.\rbrI ran a screwdriver around the edge to score the grip tape.\rbrThe scoring mark helps to make the cut cleaner. I cut off the excess with a utility knife.\rbrI poked through, from the under side in each of the eight truck holes.\rbrThe riser pad slides over the screws before adding the truck and nuts.
