|Lazy Susan and 12 inch Solderite board|
Take a ruler and pencil and mark lines from corner to corner.

Here's the trick to centering your Lazy Susan under the board: line the screw holes up along the pencil lines so that each line bisects the holes. When all the lines bisect the holes, the Lazy Susan will be centered. No other measuring required!

Once you have the Lazy Susan positioned, insert the screws (they should be fairly short- you only have 1/2 inch thickness on the board) and secure the Lazy Susan to the underside of the Solderite board. You can pre-drill if you like but I just started squirming them in until they caught since the board material is fairly soft.

Put a second board on top of the first one to keep it clean so you don't have to replace it as often. This is optional. Alternately, work on top of the board with a kiln brick.

That's it! My students have been using them for a semester now and they are very happy.
