Sign Makers Restore Historical Flying Red Horse
With more than two years of restoration, $650,000 in funding and the help of top architectural sign makers the illuminated revolving Pegasus atop the 29-story Magnolia Hotel building in Dallas is flying high once again nearly 70 years after its initial ascent to glory.
In 1934, the Magnolia Petroleum Company, predecessor to Mobil Oil, erected a large oil derrick on the roof of the city's first skyscraper, which was billed the tallest building south of Washington D.C. and west of the Mississippi. The derrick supported two 35-by-50-foot red neon signs that formed the image of a Pegasus, a mythological Flying Red Horse that was once the company's corporate logo and has since become a treasured landmark of the Texan city.
But by 1999 the Pegasus was dilapidated, pitted with rust, and unable to fly. The horses actually stopped revolving 25 years ago in 1974. Mobil moved their headquarters out of downtown and gave both the sign and building to the City of Dallas in 1977. The city eventually bolted down the Pegasus so that the rusted pieces would not fall off. Twenty-years later in 1997 the battered sign had become outdated and was shut off. But that is where this story begins.
Resurrecting a Legend
That is when Dallas-based architectural signage firm Casteel & Associates was called in to manage the project. Casteel, owner of the firm, said he declined the assignment when the project architects initially contacted him.
"I really did not want to get involved because of the type of job it was," he said. "But a friend of mine who is an architect came back a second time and said they were having a hard time getting people who were willing to tackle the job."
In the end the challenge was too compelling for Casteel to refuse.
"What made me change my mind was pressure," laughed Casteel. "But in all honesty, there were very few people who had the technical knowledge, the dedication to historical preservation and the tenacity to take a lot of different people from a lot of different disciplines and pull everybody together to make the project come off."
Project members started talking about the restoration in late 1998. Work actually began in the spring of 1999 and was well underway by that summer. While the project met its goal of completion by December 31, 2000 Casteel continues to oversee work on the rotation system to this day.
Bringing Together Specialists for a Common Cause
"The project involved steelwork, coatings, and special paintings to make the old tower last," said Casteel. "It involved porcelain for the horses. The rotating system and power transmission systems required specialists. We had a couple of different engineers involved, as well as computer programmers."
The first thing project members did was to analyze the condition of the old horse, which appears to be one horse but is really two flat, porcelain-covered panels raised by metal scaffolding that is outlined in neon. The two red horses were located 14 feet apart and were originally designed to revolve when placed on the building.
The preservation plans actually called for the sign to be restored but Casteel said that the Pegasus was in such bad shape that the restoration efforts demanded new porcelain-covered aluminum panels and a new motor.
"They were almost 70-years-old," he said. "The porcelain had been chipped and cracked enough to where rust was a huge factor. We recharged with doing the job in such a way that the new horse would last 75-100 years and so we could not actually leave the old horses up there."
What Goes up Must Come Down
The first thing project members did was to raise a Phoenix Skyhorsed crane on the roof of the building with a helicopter to disassemble the horse and then reassemble it. Dallas-based Byrum Crane Service performed disassembly of the old horses and assembly of the new horses from 400-feet in the air.
Casteel said everything about this project was a technical challenge.
"One of the challenges was that we were under very strict requirements from the City of Dallas Historic commission to restore things the way they were," he said. "We were not allowed to go in and do massive modernization."
"We could have gone in and done the job more quickly and less money had we gone in and done modernization but I very thoroughly understood that the goal was to have it look just like the old horse that was put up in 1934," he said.
Project leaders, for example, installed racing members and steel that actually served no structural purpose just so that the sign would be exactly as it was in 1934.
"You canít tell the new one from the old one except for the fact that the faces are now red and not rusty," said Casteel. "We replaced every old piece with a new piece that was exactly the same as it was before."
American Porcelain Enamel Co. of Dallas created the 15-ton duplicate. The original Pegasus is on display in a shed at the Dallas Farmer's Market.
Mixing Historic Design with Modern Materials
"The old paint actually had stood up pretty well," he said. "Unfortunately it had lead in it as most paint did from that period and we had to go through quite a remediation process to get rid of the lead."
Casteel also noted that there are some components of the mounting of the actual porcelain horses to the frame that are galvanized steal as opposed to prime steel that was used originally. This, too, was done to prevent rusting for the next 75-100 years.
Helping the Pegasus Revolve Once More
"There are still a few glitches. We've had some challenges in the rotation system within the electrical system," said Casteel. "We fought for a long time and just determined in the last few weeks that part of the problem ≠ the big problem ≠ was an insufficient ground for the computer controls and thus they were locking up regularly. We've made some changes to the control system and the rotation over the last year."
One modern feature is a technology-based system that will shut off the horse during high winds. said Casteel.
"It has air brakes, which it had before. But we eventually had to replace them because the old ones were not reparable," he said. "Now any time the wind blows above 20 mph the horse will turn itself off and the brakes will be applied. This was all done via a computer-controlled machine and that is probably the most modern part of it. We have basically a small weather station on the roof of the building that gives us wind speed and wind direction."
Casteel & Associates has worked on hundreds of custom signs in all shapes and sizes, but Casteel said restoration of the flying Pegasus was the most challenging.
"This was probably the most exciting project Iíve ever worked on, the most frustrating at times, but also the most fulfilling also," he said. "It was very neat to see the project come together."
