    I wonder if spacing the panels slightly (similar to expansion joints in sidewalks, driveways, and bridges), would reduce the expansion/contraction stresses for large models such as this where the effects of each panel add to those of its neighbors. It would be pretty difficult to lay out, without making a mess.

    Caution: CA debonder 's essentially acetone and will almost certainly remove paint. With regard to panel pop-offs, my guess would be differential expansion between metal sheeting and resin parts. Is it possible that the resin parts shrink slightly over time if they aren't completely cured initially? (Disclaimer: I know nothing about resin printing)

    Unfortunately Shapeways closed up and filed for bankruptcy about a month ago. I think the home printer market may have taken its toll on their business.

    I'm happy for you that the Shapeways canopy worked out!

    Awhile ago I had a canopy SLA printed at Shapeways using something called "Accura 60". After sanding out the layer lines and dipping in Future, the canopy was crystal clear. Here's some info: https://www.shapeways.com/materials/sla-accura-60 Not sure if this will help you, but thought you might be interested. --Derek

    That video was pure pleasure to watch. Looking forward to the next installment.

    I love your "how I did that" tips. I appreciate all the little tidbits of info that help me improve my own (much more modest) efforts.

    This is going to look amazing! Regarding drilling acrylic: I've had similar experience when drilling flat acrylic plates: after drilling what appeared to be clean holes, several days later small cracks and stress fractures appeared. After some experimentation I found that using water as a drilling lubricant prevented the fractures from later appearing. I just used an eye dropper and kept refilling a little puddle around the hole while drilling. I suspect the water has two effects: it provides cooling so the plastic doesn't melt and it also somehow allows the drill to cut a cleaner hole without chipping away at the walls of the hole.

    As long as you're putting all those lights in place, maybe you should put blue/pink leds within the engine to create afterburner "shock diamonds" using edge lighting, by adding frosted concentric rings on the outside of your clear support rod? You might be able to achieve an effect something like this:

    Stellar. I like how you documented this project and especially how you described the painting and color process. I learned a lot. Too bad about the flecks inside the front canopy. It's probably happened to everyone. I've learned to completely seal the cockpit tub all around where it meets the fuselage interior in order to prevent sanding dust from working its way in during subsequent work on outside areas. Also I fully blow out the cockpit with (empty) airbrush at high pressure to get rid of any pesky dust that might be sticking underneath instrument panels, seats, etc before sealing the canopy. Again, great job.

    A lovely work of art. You really need to pose it with a nice uncluttered background for some beauty shots.

    It is indeed a "white rocket" :)

    All that panel work is really going to look good when painted. Love the decal on back of pilot helmet. Don't rush to get it finished! It's going to be a beauty.

    I used original Rockwell / North American Aviation drawings for the B-1B, obtained here: http://www.aerospaceprojectsreview.com/catalog/drawndoc.htm "Airdrawing 2" and "Airdrawing 18" This was a great resource. You place an order via paypal and he email's you a temporary web address and password from which you download the .zip file containing the drawings. I used a program called "Imagemagick" to convert and rescale the desired image ("B-1b.gif") into a pdf file that I took to a local Office Depot and had them print on one of their big architectural printers (48" x 36") for about $7.

    I'm planning on adding "EL" (Ellsworth) markings eventually. My son will be PCS'ing there sometime this year as a pilot. I'm waiting to see what plane(s) he'll be flying so I can pick something appropriate.
