TAP 10 + 26 Luthier Kit
The 10.5 x 40" and 26 x 28" TAP bags fit the multiple shapes required for luthier projects. Fitted with Quick-Lock connectors, these bags connect individually with the TUG External Valve.
Thin Air Press 10.5x40” Bag Project Size Guidelines:
Project stack width PLUS thickness must be less than 6.5”
Project stack length PLUS thickness must be less than 34”
Thin Air Press 26x28” Bag Project Size Guidelines:
Project stack width PLUS thickness must be less than 22”
Project stack length PLUS thickness must be less than 21”
It is important to not have the seams stretched open when it is under vacuum as it will split them apart. These guidelines ensure that there is a recommended 2” wide perimeter of flat vinyl all around the project in the bag.
The TAP 10 + 26 Luthier Kit contains:
- one 10.5x40" and one 26x28" vinyl vacuum bag with Quick-Lock connectors installed
- an opening seal attached to both TAP bags
- a clear acrylic TUG External valve with one-way valve and Quick-Lock connector
- 1/4" tubing
- a high-pressure manual vacuum hand Super Pump
- breather netting
- extra sealing tape
- illustrated instructions
Insert your glued veneers into the vinyl vacuum bag, position the breather netting and seal the bag. Connect the 1/4" tubing to both Quick-Lock connectors (on the bag and the TUG External valve). Place the manual pump onto the grey valve and pump the air out.
Before you glue up your veneers, a dry run is highly recommended!

Tips are included on the maintenance sheet included with the kit.
Keep your TAP bag working efficiently by keeping the sealing tape clean, replacing the paper strip back after each use.
If you suspect leaks in the vinyl, inspect it regularly (see video) and use clear packing tape to stop up any possible leaks.
Maintain the pump with plain water, or a light spray of oil to keep the slide moving freely.
Ensure your valve has not lifted away from its base, and that the top cap is free of any sawdust, foam bits or glue.
Handle and store your TAP bag so that nothing sharp can puncture it.
Q: Where do I find out how to bend single sheets of veneer that are used in this video?
A: Click this link to see how Behrad does his technique.
Q: Is this reusable, and for how many times?
A: The kits are designed to be used many many times. With a little care and maintenance, the TAP Kits will last for years.
Q: Will the glue stick to the bag?
A: PVA glue and epoxy will not stick to the bag. Any dried glue can be loosened with fingers and either shaken or blown out with a shop vac. Do not use polyurethane glue as it will damage the vinyl and ruin the bag.
Q: How many pieces can I press at once?
A: You are limited by how fast your glue dries. If using slow-set epoxy, you have a generous amount of time to work before it starts to set. If using water-based glue such as Titebond III, you have about 7 minutes to get your project pressed before the glue dries. Dry glue will not bond together.
Q: If the TAP Bag gets a hole in it, can I fix it?
A: Clear 2” packing tape seals up any suspected punctures. Use a length of the butyl tape to fix any side seam gaps or splits.
Q: Do the valves leak?
A: While many people assume air is leaking back through the valve, they are made of cast rubber and almost never leak. The most common problem with slow leakage is the open-end seal tape. If the seal is not properly closed up (check both sides) you will lose vacuum. If the top cap of the valve is not compromised with dust and debris, the valve will not leak.
Q: Do you refund my veneer if I screw up the pressing?
Q; What’s a “Dry Run” and why should I do that?
A: It means to press your project in the TAP bag, without putting any glue on the veneer sheets. Stack the dry sheets of veneer over the mold, seal them into the press with the breather netting in place, and pump the air out. Check for 10 minutes to make sure the TAP bag is not leaking. This will help you become familiar with the process before you commit glue to your veneer sheets.
