2017-03-28 (Tu) Pi0 Laser Tag PiTagErrUs

Yesterday, parts used to draw center lines on tubes were modeled but it may not have been clear how they were supposed to be used. Today, instructions have been made on how to use the parts.

First, print the parts. There will be two mirror images of each other. Sanding may be necessary on the ends, depending on the tolerances of the printer being used. The parts pictured below were printed with low infill and the print job was interrupted so the tops weren't even closed but these worked well.

 Printed parts with black ABS pipe

Don't worry about alignment, put one part in each end of the pipe to be marked. For demonstration, and possibly a laser pistol, a short piece of black ABS tubing was used. This tubing had the same measurements as PVC pipe but it was lighter and cost more.

 Tools purposely misaligned on pipe

To ensure the dividing tools are properly aligned, place them on a flat surface, like a desk or the floor, and press down so they twist. All that downward pressure makes sure they are facing the same direction. Depending on how snuggly the tools fit into the PVC, this step may require some effort. Or it may very easy.

 Lining up the tools on a flat surface

Now that the pieces are aligned on the PVC, it is a simple matter to place a straight-edge, an aluminum ruler in my case, onto the edges of the tools and draw a line.

 A layer of masking tape was put down beforehand since a black marker wouldn't show up on the black tube.

Drawing a line with the alignment tools

A quick animation below shows how the lines came out neat and spaced properly. These tools should make sure the next taggers are well-aligned.
