Octagon Port Part 2

To make the center part of the octagon port I used a circle cutter in my drill press to jut the various sized circles needed out of the appropriate thicknesses of wood.

Here are the disks that will make up the part. I did the bottom one out of styrene to make it easier to glue it to the housing.

I glued the pieces together and aligned them with a dowel.

I did not try to cut the dowel to the exact length, instead I left it a little long on each end so I could and it smooth later. To be able to clamp this I used a few washers around the dowel on either end.

Since this part and the housing will be different colors I did not attach them together yet, I will do this after they are painted.
