Have you ever knocked over a cup of water and soaked the project you were working on? I did yesterday. I always keep water and a chip brush handy when I'm gluing wood- I like to clean up the glue that squeezes out when you clamp wood while it's still wet instead of sanding dry globs of it after the fact. This quick spill-proofing sleeve will keep your work surface dry.

Step 1: Stuff You'll Need

Tools

Tape Measure
Combination Square
Calipers
2" Washer
Hole Saw
Palm Sander
Saw
Drill

OptionalTools

Band Saw
Chop Saw
Disc Sander
Table Router
Drill Press

Materials

Wood (at least 1 1/2" thick)

Step 2: Choose a Piece of Wood

I found this on site, I think it's walnut. You could do this with any kind of wood, but a hardwood like this will last longer.

Step 3: Cut and Square the Edges

Cut a section of the board against the straightest side, This will give you a right angle to start with. Starting with the fresh cut side, cut a 5" X 5" square.

Step 4: Make a Square, Drill the Cup Hole

Measure the cup and choose a hole saw that's slightly bigger than the cup. Draw an 'X' from corner to corner on the piece of wood, and drill a pilot hole at the center. Use a hole saw to cut the cup-hole

Step 5: Make an Octagon

Draw a line perpendicular to the X. The center point should be the same distance from the circle as the square sides are. This will give you a perfect octagon, but it can really be any shape you want. The band saw will give you straight cuts quickly, but you can do this on practically any saw.

Step 6: Finishing

Use a 2" washer as a guide to mark 1" radiused corners with a pencil. A disc sander will give you flush edges, but you can finish the edges with any kind of sander. I also used a table router with a 1/4" radius bit for some nice rounded edges. I left mine raw, but if you really want to get fancy use some danish oil.
