Vacuum Jigs

These are two vacuum bases.  More or less they are a simple plywood sandwich with the appropriate channels created within.  If you look closely you'll see the small air holes on the unit in the vise.

These clamp bases are handy when the edges of boards need to be routed, it eliminates conventional clamps and the need to reposition them mid-process.

Vacuum Drill Base Top This is a handy portable drill press stand that uses a vacuum to clamp itself down to a surface.  It would serve the same purpose as a portable magnetic drill stand.  I don't use this jig often but when I need it I really need it!

This jig would often be used where one would prefer to use a real drill press but either the material to be drilled is too inconvenient to get to the drill press or impossible, for example, the side of a 400lb cabinet.

This is the bottom of the jig shown above.  The vacuum area is divided into two sections to make it easier place the jig onto surfaces with a fair amount of overhang while maintaining a good vacuum seal. Vacuum Drill Base Bottom
Vacuum Jig Edge Guide This is another vacuum jig.  Shown here are two sizes of an edge guide,  the smaller one is turned upside down to reveal the foam tape used to maintain a seal.  When I use these jigs on stock shorter than they are I put a piece of tape over the vacuum ports that are unused.

The longer jig uses both a source and supply fitting, that gives it the capability to daisy-chain on to another vacuum jig if needed.

The small piece next to the long edge guide jig is the reference, in this case the jig is placed exactly as far away from the cut line as this piece is wide.   The width of this reference is sized for a 1/2" diameter bit in a Bosch 1613 router.

These jigs could have been constructed with a commonly applied T-square section but I prefer to align these jigs to a drawn line.

This vacuum jig was designed to aid in assembling cases.   The jig is actually two vacuum bases, the horizontal base has in "inlet" fitting as well as an "outlet" that is connected to the vertical base.   This manifold allows the vertical base to be turned on/off if desired.  I haven't used this nearly as much as I thought I would.
