Roarockit Thin Air Press vacuum bags distribute even clamping pressure on all sides of your project, ensuring an excellent bond on curved veneers and bent laminations. Just slide your veneer project into the TAP bag, seal the open end, then remove the air with the manual pump. Once the air is evacuated, Roarockits ingenious one-way valve and air-tight seal maintain the pressure until the glue dries, eliminating the need for an electric pump to cycle on and off. Perfect for almost any wood laminating, veneering, and marquetry project. Features: An inexpensive introduction to vacuum laminating—includes everything you need to get startedApplies even clamping pressure—no pressure points from clampsIdeal for table tops, clocks, boxes, game pieces, marquetry, picture frames, golf discs and moreReuse again and again—other size vacuum bags available to suit your projectHand pump included; no power requiredPVA and epoxy glues will not stick to the bagNot suitable for heat or steam bending; room temperature should be at least 65° so the vinyl remains flexible Note: Be sure to check out the Rockler Vacuum Bag Port Adapter (#50665, sold separately), which lets you attach an electric pump for even faster, easier vacuum press veneering.
