Small Plastic Plate (SPP)

Material/Equipment:

• Stabilizing plate
• Plastic sheet
• Drill press
• Bits set

Purpose

• Holding laser source and camera, and ease to align them.

Procedure

• Use a bit (a circular cutting blade, like that from a hole saw) to cut a circular shape piece with the diameter of 1.5’’ from a big plastic sheet. There should be a hole of diameter 0.3’’ at the center of the plate after cutting.
• Repeat the previous step to make multiple items.
• Replace the bit with 0.2’’ diameter bit.
• Stable the stabilizing plate onto drilling surface of the drill press table. Adjust the drill press table so that the bit can go through the small hole (on the stabilizing plate) as the bit moving down.
• Put the circular shape plastic plate on the stabilizing plate. Stable it by putting a 0.1’’ diameter bit through the plate and into the smaller hole on the stabilizing plate.
• Drill a hole on the plate by pressing the bit down.
• Remove the plate.
• Adjust the drill press table so that the 0.2’’ diameter bit can match with the other 0.1’’ diameter hole on the stabilizing plate.
• Put the plate on the stabilizing plate, stable it by locating 0.3’’ and 0.1’’ bit into the plate and the matching holes on the stabilizing plate.
• Drill a hole on the plate by pressing the bit down.
• Remove the plate
• Repeat the previous step for the other hole.

Expectation

• The two smaller holes have to be symmetric. The bigger hole has to be at the center of the plate. All the dimensions have to be correct.
