Yup there is a bunch of smoke cutting plywood due to the glue they use to laminate the plys. My laser has a 6" dia vent/fan system to draw out the smoke and fumes. |

Is 1/4 too thick? Shucks, I'd hate to have to re-draw it, but I can be done. More time than headache, really.
Oooohhh, I know what else Rev X03 is getting. Tabs! ETA: I fixed all the design errors, everything will fit together properly now. Now all I have to do is fix the BoM (AKA parts list) and clean up the drawings a bit. The fixits weren't done with a ruler. :blush: What's a good size of ply? I think a re-draw for thinner ply won't be too bad, all I have to do is enlarge the inside pieces to make up for the thinner outer pieces. I'll even take a stab at putting in a couple tabs. Woooooo! My 2000 th post! Where's my prize? |

1/4" is a good size, but some lasers could have trouble with it. Also, not only does the glue on birch ply cause a lot of smoke, it also causes a lot of charring on the edges.
However, 1/4" lite ply is much easier to cut, and with much less charring. My gut feel says it should be OK for your flight box. |

Regular aircraft ply is birch. Very hard, heavy, strong.
"Lite Ply" is poplar. Not as strong, softer, significantly lighter (both in color and in weight), generally only has three layers, while the other stuff usually has five. Lite ply normally comes in just 1/8" and 1/4" thicknesses, while birch ply comes in a wide variety of thicknesses, all the way down to 1/64". |
