Artwork circa 1983 depicting the Bell BAT (“Bell Advanced Tiltrotor”… so… ummm… the “Bell Bell Advanced Tiltrotor”) single-seat small military tiltrotor designed to compete in the LHX program. It is shown here in two modes. The nearest aircraft is in full forward flight; the aircraft in the background is hovering. Both are in the process of firing unknown anti-tank missiles at a column of Soviet armor.
Ran two prints today. The second one, the 4th test of the new setup, turned out to be pretty much there with just a few minor issues. The main issue I’m looking at now is getting proper coverage of the paper. For whatever reason, the cyanotyping fluid doesn’t really like the vellum paper and you get occasional blotchiness. This was a constant problem before, and was solved largely by tossing prints that weren’t up to code. Experiments will continue…
Todays test involved mounting the UV light bar to a crude frame and just letting it run, not waving it over the print like an idjit. As you can see most of it is pretty uniform; the end of the print that was furthest from the light bar wasn’t adequately exposed. However, come the weekend two more UV lights will arrive and will extend the reach.
The learning curve this time around is going *much* faster than the first time. This should probably not be a surprise, but it’s nice to see that things are trending quickly in the correct direction.
And here we are:

There are of course comments by people who don’t understand the concept of “context:”
Baby it’s Cold Outside is about a woman in the 40s, who was worried about the neighbors gossiping about her being unchaperoned with her boyfriend after a certain hour, and deciding not to worry about what they think, you perverted l0ser.

And so Adam Savage goes to the Royal Society In England and gets to look at not only a first edition of Newton’s “Principia,” but the actual *manuscript.* And both he and the archivist handle them with their bare hands.
Shudder.
There are books that *I* own that I hesitate to actually touch without cotton archival gloves. But the Principia? Dude, I wouldn’t touch that unless I was fully sealed. I’d be deathly afraid of not just touching it, not just sneezing on it, but simply *breathing* on it.
The Pushkin State Museum of Fine Arts caught fire this morning…
Huh. Together with that shopping mall, makes ya go “hmmm.”
I am going forward with the return to cyanotyping. I’m gathering the supplies needed to rebuild the capability; learning some lessons from before, this setup should be a little better and a little bigger. I should be able to make prints 24 inches by up to 7 feet. It’s a bit of a chore and certainly an expense, but the end results will, I hope, be an improvement over what I produced before.
As before, I plan on taking commissions. I don’t care what it is… aerospace diagrams, ships, architectural diagrams, sci-fi movie prop diagrams, gay wedding cake layouts… if it can be blueprinted, I’ll do it (for a fee). So if you have anything along those lines you’d like blueprinted in the old-school cyanotype fashion (white lines on a Prussian blue background), made by hand using chemicals, sunlight and effort rather than hitting “print,” let me know. Something I will try again is blueprinting onto linen. I ran off a few back in the day; interesting, but perhaps a bit niche.
Some years ago I produced a range of cyanotype blueprints of a number of aerospace subjects. The hardware needed for this was disposed of when I left Utah at the end of 2019, so starting again seemed unlikely. However, someone has expressed interest in a special commission. Rebuilding the hardware needed will be an expensive chore, and sadly getting the large format transparencies printed looks like it will be much more difficult here than it was in Utah. Nevertheless, at this point it looks probable that I will restore that capability sometime in the next few months, assuming one further detail can be ironed out.

When I get back to it I will probably focus on the larger format stuff rather than the smaller prints. I have plans on how to improve upon the prior hardware to make things work better and more efficiently. If there are any of the former large format prints you’d like to see returned to production, or you have any prints you’d like to see, let me know. And once this is up and running I plan on trying to take commissions, working with a local print shop to find customers interested in this somewhat unusual and certainly obsolete form of art.
If you have a diagram you’d like me to turn into a cyanotype, contact me. Commissions aren’t going to be restricted to aerospace subjects; naval, architectural, movie props, whatever you’ve got, so long as it *can* be blueprinted, once things are in place I should be able to do it. 
A Beech Aircraft Company concept for a civilian VTOL for the 1980s, from circa 1971. This would be a two-seater using tilt-ducts. This appears to be less “engineering” and more “art,” as there are some definite headscratchers about the design. Where are the engines? In designs such as these it/they are typically in the fuselage, driving the ducted fans with shafts. But no provisions for inlets or exhausts are evident. So the engines would probably be in the nacelles themselves but there doesn’t seem to be room for them. The cockpit canopy is expansive and would provide a *fantastic* view, but it seems to be sized only for people who have had their legs amputated. The configuration, unlike your average tiltrotor, seems perfectly capable of horizontal runway takeoffs and landings, but the use of skids rather than wheels would make that problematic. The disk loading would be impressively high, and the resulting blasts of air from the ducts would likely tear anything short of solid concrete to shreds.
How boomers ruined society: he’s not wrong.
