Putting the thing together:
This tool is made to be two parts that are bolted together, do not glue the whole assembly together or you won't be able to open it up to replace the handle or sliding plate.

Step 1:
-Push nuts into the wooden plate with rectangle holes for them, glue the top three plates together up to the plate that says no glue.
-glue together the second part of the seeder plates [so it is now two halves].
Wait for the glue to set.
-Glue the handle together

Step2:
-Bolt the whole assembly together before the glue has time to set

Step3:
-using super glue or similar glue the magnets into the seed plate and the main housing so that they attract, the magnets hold the seed plate and unit together.
-Once the wood glue has set you can insert the handle and acrylic seed plate, then start using the thing. Line the handle and plate gears up so that the handle bottoms out both ways before the slide plate bottoms so that the gears cannot try to push the plate into the side of the housing.

The seeder plate is designed to slide in and out, so changing seed type and hole side is quicker. Suited ideally to round seeds or pelleted seeds.
