P-38J Lightning – CNC Files For The Laser Cut Miniature Model

Lockheed P-38J Lightning - miniature 1:212 laser cut foam model
Here is another model I’ve designed around the size limitations of Groover’s micro laser cutter from discarded DVD drives – 1.5″x1.5″. I wanted this model to be in the same scale as my earlier Supermarine Spitfire model – 1:212 scale after seeing a 1944 photo in Famous Aircraft: The P-38 Lightning (by Gene Gurney)
picturing a P-38 (F-5 version on a reconnaissance mission) accompanied by a Spitfire and the caption said: “Two of the fastest aircrafts in the world at the time this photo was taken”. I though it would be nice to see them together again, materialized on a much smaller scale

I’m going to build the Groover’s Pocket Laser Engraver at some point in the future but so far not much luck with CD drives I’m disassembling (two so far). Both were very old drives (1996 and 1998) and (shocker!) things were much simpler back then Read the rest of this entry »

The idea for this model came to me when I was browsing Instructables and came upon this nice project – the Pocket Laser Engraver. Basically, its author, Groover, describes building a laser diode cutter not unlike the one I’m using here but based on parts of discarded DVD-RW drives. In fact, the diode he’s using is also salvaged from one of those drives. I got intrigued by the project due to the fact that I never throw anything electronics away and I have a little stash of CD and DVD drives myself that I would love to put to some fun use.
