Building a Portal Turret with motion controlled audio and lighting

Step 12 Details

We're down to just the last dew detail pieces and the turret is finished.  First up will be the detail piping on the inside of the side body cavities.  These are 1/4 inch black Delrin rods I bought from Interstate Plastics.  Any plastic supplier will probably carry them.  I cut them down to the rough dimensions for each piece needed and then used a heat gun to bend the shapes.  To help the plastic set quicker, I dip the rod in cold water to cool the plastic.  I then created small styrene mounts for these.  They are the tiny white squares that the black rods go through.  I sanded the edges smooth and then cut down the excess Delrin.  In the second image below you'll see a few that have already been trimmed and a few that haven't.

The next detail piece is the gun barrels.  There are four in total.  Two longer and Two shorter.  I started with a hole saw and cut a bunch of circles out of MDF.  You can do this with just a band saw and a sander. 

The last detail piece is the 2 antennas. These are pretty straight forward in there construction.  I picked up some styrene piping from a local hobby store and used the same method as the Delrin to shape them.  A short time under the heat gun and they are easily bend to the desired shape.  A quick coat of silver spray paint and they're all finished
