Here is a shot of the propulsion module details.
Photo etching?? No.... CNC.
I pushed the machine to the max with this one for sure.
Using a 1/32 end mill I was able to create all of the outlines.
I also needed to duplicate 1" and 1/2" size holes in 1/48th scale which meant getting out the pin vise
and micro drills.
I think we all know how easy it is to snap a #80 drill bit.
I decided to give it a try in the CNC machine.
How to chuck up a hair size bit??? Just chuck up the pin vise itself.
I actually was able to peck drill at .001 depth levels till it went through the metal without breaking the bit.
I guess I was a little premature getting that Photo-Etch kit.
