On Thursday, August 1, 2019 my scanning vendor arrived on site to start
scanning the molds. no battle plan survives first contact with the enemy,
and this was no exception. Due to a miscommunication, a portable air
conditioner was NOT in fact arranged for the portable garage that I bought.
Said Harbor Freight portable structure wasn't able to stand up to a stiff
Florida breeze and wound up across the parking lot overnight, bent up, and
had to be set back up again to provide poor Nathan (the scan tech) with
SOME sort of shelter from the ferocious Orlando August sun.

While I was dealing with a difficult judge in a difficult venue, my wife
was helping Jim Bounds with Day 1 of scanning. It was hot miserable work,
but we learned a lot.

For Day 2, I was on hand as well as Jim's assistant. The owner of the
storage yard let us move the scanning into his forklift barn. Hooray for
solid concrete floors, a roof to keep the sun and rain off, and electricity
to drive fans and other equipment! It made all the difference. The portable
garage was unceremoniously scrapped. With more area to work, production
picked way up on getting the molds scanned.

Bad weather moved in, and it was clear we weren't going to finish the whole
project (shocker, I know) that day, so we called it quits and will make
plans to finish up over another couple of days sometime in the coming weeks.

Looking forward to finishing the project and seeing the cleaned up
datafiles, and figuring out what techniques may be best suited to reproduce
our parts.

What a monumental endeavor, get a big enough 3D printer and you can print a new GMC! Thank you for preserving our future, this data would have been lost forever.

Robin, thanks! We will live on into the future.
Now, after a tour of RCR courtesy of Barry Owen and Rich, I have an idea. If we could fit it in (I didn't measure to see if the scaffolding was tall enough) what's the chances we could get the Childress folks to run a 23' and a 26' through their scanner complete? We wouldn't need the NASCAR filter, just a complete scan of a finished coach. Could someone ask Barry if that's even remotely feasible? We would then - when Robin finishes - have a scan of each part and of the finished product.

The scanner they've got can scan the entire outside of the coach. As long
as the handheld unit knows its position in space, it can just look at
anything. They've scanned entire airplanes.

That might well be sufficient. However, the NASCAR system is a hoss. I believe he told me the maximum error is a thousandth of an inch throughout. I'd believe it.
