Adam Savage has a bunch of old (decades) silicone molds sitting doing nothing. Silicone, sadly, degrades not just from use, but over time; a mold that is years old will almost certainly fall into ruin if you try to cast a part using it. So, if you have an old mold that you want to get parts out of, what to do? Well, if you are well connected you get someone to CAT scan the mold, create an STL model of the mold, convert the hollow space within into a solid model, then 3D print. Easy! Anybody can do it! But here’s the thing: each scan the CAT scanner makes takes 30 seconds… and each mold could take 1500 scans to complete. So… twelve and a half solid hours on a CAT scanner.
Huh.
After watching these videos, I’m glad I passed on buying into the Mars Industries 1/18 scale “Airwolf” kit. There are a lot of problems with it. A *lot* of problems. There are design issues, uncured resin, quality control issues and, most shocking to me, problems with the vac-formed transparencies. The problem with *those* was that the forms were themselves 3D printed, which is fine… but the prints with their substantial layer lines were not sanded smooth. Thus the transparencies have layer lines. AAAARRRRGH.
I’ve added some more things to my eBay: “Dynascott.” There are some new cyanotypes, some books, a piece of vintage NASA test equipment that I bought *years* ago to serve as a prop for The Alternate History Movie That Shall Not Be Named. Some cyanotypes I’ve had before; the photos are of the *actual* prints I’m selling. I have more cyanotypes and a lot more books to add soon, but this gets the ball rolling. I’ve included Buy It Now for them.

I’ve never gotten into RC aircraft. Partly because I know that I am fated to spend thousands of hours building something only to have it promptly flop over two seconds after I launch the thing. But static display models? All about that. So this electric RC B-1B bomber looks intriguing. At $800, it’s out of my price range and I *certainly* don’t have a place to display it (seems to be about 1/23 scale)… but that doesn’t change the fact that it’s just neato.
The Fairey Rotodyne was a valiant but doomed attempt to develop a high speed civilian passenger VTOL. Decades ago, the British Airfix plastic model kit company released a decent model of it, but it has been unavailable for a good long while. They’re bringing it back out.
Two separate projects to create virtual Discoveries from “2001.” Neither one is complete, both are interesting.
