GOING UP!
I am going to use a 25th scale Lowrider Wheel for a Vertical Thruster. I traced a circle with the circle template.
I started the hole with an X-acto Knife.
I used a Reamer to make the hole larger. Then I used a Sanding Drum, by hand, to smooth it out a bit.
Here is the Thruster in place. I'll put a black wash on it later...
More Coming...
