This is a project that can be done over a few days. It takes some time to sand the edges of the cubes, and you'll need to allow a few days for glue to set, and paint or stain to dry.
I turned my little Tetrimino blocks into magnets, but you could make them into anything really.
Step 1: Supplies
You'll also need the following:
- Sandpaper (I used somewhere around 100 grit, but if you want a smooth finish be sure to get some higher grit, too)
- Tack Glue, or Wood Glue
- Wood Stain or Paint
- An Idea for the End Product
Step 2: Know Your Tetriminos
I - Made up of four blocks in a straight line.
O - Four blocks which are formed into a 2 x 2 square.
J - A column of three vertical blocks, with one placed to the bottom left.
L - A column of three vertical blocks, with one placed to the bottom right.
T - Three blocks forming a row, with one added below the center.
S - Two stacked horizontal blocks, with the top one offset to the right.
Z - Two stacked horizontal blocks, with the top one offset to the left.
Step 3: Sanding
If you're low on patience (and high on ingenuity), you can make yourself a jig to bevel multiple cubes at a time, or make something that would hover a power sander. As for me, I just start a Star Wars marathon and work my way through a bunch of cubes.
Once you bevel off the edges, you need to decide if the cubes need to be sanded with a finer grit paper, or if you like them the way they are. I decided to leave them the way they were.
Step 4: Gluing
After some testing with Tacky Glue I decided the strength of that bond (and low drying time) would be more than suitable for my applications.
Once you decide on your adhesive of choice, you can begin to arrange your wood cubes into Tetriminos and start applying adhesive.
Note: If you plan on staining your Tetriminos, be sure to arrange them with the wood grain all facing the same way.
Step 5: Painting/Staining
I decided to stain my Tetriminos, and found three different Minwax Wood Finish cans to do the job. The Tetriminos got divided up evenly between the three cans, and once I moved to a well ventilated area, were ready to go. It was kinda hard to take pictures of this process since my hands were somewhat covered in stain up until the end.
Depending on your proposed use for your Tetriminos, you'll probably want to coat them with a protective clear finish, or seal.
Step 6: Make Them Useful!
A few ideas ran through my mind, but I was in dire need of some spiffy magnets for my white board. After collecting some spare (SUPER TINY) Neodymium magnets I had laying around I proceeded to glue magnets to the backs of each Tetrimino. If you really want to go all out, boring a proper sized hole for each magnet would be awesome.
That seems to be everything...
