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

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


  • Band Saw
  • Chop Saw
  • Disc Sander
  • Table Router
  • Drill Press


  • 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.

    Or make a heavy weight base by putting the glue jar in a larger short tube or cup(of any type material) and pour some plaster or concrete between the glue jar and outer container. Stays where your put it and resists tipping if if accidentally hit.

    Made something similar as a pad between my frying pans so that the non stick surfaces don't scratch / damage themselves,

    That's true Wayne, but there's nothing pretty about a roll of duct tape!

    a roll of ductape will do the same thing

    Tanzer26, good idea- do we get to see an instructable for that one? Hadn't though of using a Forster bit (honestly didn't know what it was called until just now). Good point on the sequence of steps. The clamping on the 5X5 piece felt a little precarious.

    I just had another thought. Use a forstner bit, stop with 1/4" of wood remaining and you could make spill proof drink coasters.

    Great idea. Like a cup holder in my car. I'm going to have to make a couple of different size ones. I would suggest, drilling the hole, before cutting the square from the board. That would allow clamping to the drill press. And I have a strong preference for forstner bits, for large holes.
