Thanks Ted. Remember, these were made long before the advent of the digital camera. What a
difference that has made. Unfortunately, I do not have photos of a lot of my early stuff. I
did find these. A photo of this one appeared in CAMPAIGNS magazine NOV/DEC 1982 so the model was
built sometime in 1982.

The title was "The Great Train Hold-up", a play on words because the "hold-up" was waiting for
those officers to have their photo taken, rather than a robbery, ca. American Civil War.

The scale is 1/25 and the engine and tender were modified from a large plastic kit. All the
figures started out as American and German WW II plastic figures. The railway gun was
scratchbuilt. The diorama had been on permanent display at the Association of the US Army in
Alexandria, VA for many years.

, Bob, here is another coincidence, I was stationed at Arlington Hall Station, The Intelligence and security command, in Arlington, VA. In 1982. I have visited the association many times'...during that time period'...Beautiful job on that outstanding model'...Thanks Bob, for digging through your files'...I'm sure your efforts are appreciated by all viewers'...

Great job Bob,
Another one of my passions is the Civil War! I like to read about the history of the Civil War. A few years ago I made six 8" tall clay figures of Lee and Grant and soldiers of both sides.
It was very thoughtful of you to donate the display to the US Army Association.

Bob, Your early models show promise. if you stick with this model building stuff you might make a good go of it :) And even back then...a punny title. Nice stuff !

Marvelous modeling, Bob! That Civil War scene is definitely museum quality.

Thanks for your posts, all of you.

Ted, you predated my visits to the Association of the US Army. In the time frame of about 1997
through maybe 2005 or so I was commissioned to do 4 ship models for the association and 4 more for
General S. personally. It was during this time that I donated the Civil War diorama to the
Association.

Jeff, I think you are familiar with my model of the side-wheel steamer MAPLE LEAF. That was done
on commission for the Association.

Bob

One last nostalgic (for me) photo that I dug out and it's actually within the subject of
"structures" too. I have posted photos of some of the structures made from the resin parts I used to
make and sell but I don't think I ever posted photos of any of the many vacu-formed structure
kits I made for sale. These were two Victorian houses in 1/32 scale.

Bob

Those are great looking models! I like all the different textures and colors. You seem equally comfortable and adept with all varieties of architecture and building materials.

Awesome! I'm surprised at how detailed those vacuformed structures are.

Wonderful structures!
Bob, you are a man of many surprises. How does vacu-forming work? Did you make a mold of a build or??

Mike, Ray, and Dave, thanks for your posts.

This may sound crazy but here's the way it went.

1. Make the structure (or kit parts) in my old favorite material, STYRENE, who would have guessed it?

2. Make a rubber mold of it.

3. Make a rubber mold from the first rubber mold.

4. make a resin casting from the 2nd rubber mold.

That results in a hard resin negative of the structure which is placed on the bed of the
vacuform machine and heat softened styrene is sucked down INTO that mold.
If there are any areas in the test piece that do not get sucked down into the mold properly you
then drill small holes through the mold so that the vaccum will pull those down into the details.

You can do that easier by making a hard resin casting from the first rubber mold and sucking
the styrene down OVER that but the detail is nowhere near as good.

You could also eliminate some work by making the master from other material that will stand up to
the heat and pressure of the vacuform machine and then sucking the styrene OVER that but
still, the negative mold produces a much better detailed product.

Bob

Thanks for explaining. It sure sounds like a lot of work with the potential for many things to go wrong.
