Sandblasting Precision Board HDU: Tips from SignCraft Readers

Sandblasting Precision Board HDU can allow for many more interesting and subtle textures than a wood sign.  In addition to sandblasting much faster than wood, it allows the sandblaster to move much closer to the surface.  Because of the low blasting pressure, the detail and shapes can be much more subtle.  Dave Showalter of David Design and Danny Dean of Dynamic Signs Design recently wrote into SignCraft Magazine with their tips for sandblasting HDU.  They also sent us photos of some of their signs, fabricated from Precision Board high-density urethane foam, manufactured by Coastal Enterprises.

Danny Dean, Dynamic Signs Design, Rice Lake, Wisconsin:

Sandblasted effects on HDU
“I like to mix textures when sandblasting a high density urethane sign. I may blast the background through the Grain-Fraim [www.grainfraim.com] to get a wood grain effect, then blast the border or a panel directly to get a stucco or stone effect.
I like the contrast of the stucco finish against the woodgrain.
I sometimes make a template with a slot in it that lets me blast faux mortar joints for a brick or stone look. You can create a stone effect that way by monkeying around with the sandblast to get an irregular surface.”

David Showalter, David Design, Bryan, Ohio:

Make sandblasted HDU woodgrain look even more realistic
“I often sandblast high-density urethane through the Grain-Fraim to simulate sandblasted woodgrain backgrounds. Over the years, I’ve found that a couple of tweaks during the blasting process that make the effect look even more realistic.
First, my sandblaster does an initial blast through the Grain Fraim. Next, he moves the Grain Fraim about an eighth of an inch up or down and continues blasting. This really creates a great look.
Finally, we remove the Grain-Fraim and continue blasting. It deepens everything. It just adds to the effect and makes it look more realistic.”

The Hotel Settles Gets An Incredibly Detailed Architectural Model

Tom Pantuso with B&T Model Railroad Building and Design Works LLC used Precision Board high-density urethane to fabricate an incredibly detailed replica of the historic Hotel Settles in Texas.  At almost six feet tall, the model replicates the hotel’s 150 rooms, restaurant and pharmacy.  Pantuso went with Precision Board because he knew it would be able to handle the intricate details required while also holding up to the elements.  Read on to see how his team completed this monumental undertaking.

Tom used PBLT-15 Precision Board HDU to make the castings and molds for the door frame and window molds. It was also used for the exterior of the building.

“I used Precision Board on the CNC machine to make the original casting for the rubber molds that I would then cast the windows and doors from using plastic resins from Smooth Cast,” said Pantuso. He added, “most of the actual model was constructed using SketchUp and Blender.”

 

They began to break the overall model apart into different sections to make it easier to build.  They did it in sections and put them all together using a plexiglass interior.  The brick work was done using either a 1/64th bit or 1/32nd bit.

“Once we had a 3d model in place, we got to work cutting the Precision Board.  Because we had so many intricate pieces to cut, it took us about four months on the CNC alone,” Tom said.  “We used several different router bit sizes, including 1/4″, 1/2″ and 3/8″ on the urethane foam.”

The main reason Pantuso chose to use Precision Board HDU was that wood was too hard, and hardware store foam wasn’t high enough density.

“Precision Board cut like butter and held the shapes well,” said Tom.  He added, “with 250 windows and doors to fabricate, the only product out there that would allow us to not go through thousands of bits and be fast enough to get the model produced in a short period of time was Coastal Enterprises’ Precision Board.”

The Art Deco routing took Pantuso’s team four to five months to rout, mostly because of the precision of detail needed and the fact that Tom didn’t want to rush the cutting process.  They tried MDF and other substrates, but nothing worked as well as Precision Board.

Pantuso’s team painted the urethane foam using regular primer and then hand-painted all the details over several months.

The model was commissioned in February and installed in November.  The modeling took three months and then it was an additional three to four months routing all the material 24/7 to get it done in time.

According to Tom, there was an unintended side effect from adding the model of the Hotel Settles to the TrainTopia display.

“The hotel looks so good that it’s making the other buildings look like cardboard boxes, so we’ll be going back and upgrading some of the other buildings using Precision Board.”

The Museum of the American Railroad, located in Frisco, Texas, is pleased to announce the latest addition to TrainTopia, The Hotel Settles.

Designed and built by B&T Model Railroad Building and Design Works of Keller, Texas, the beautifully detailed G-Scale model rises majestically almost six feet above the busy streetscape of TrainTopia.

TrainTopia is a million dollar permanent year-round model train exhibit donated by the Sanders family and made possible by the current hotel owners, Brint and Amanda Ryan.

Hotel Settles opened in 1930. It boasted 150 rooms, and included a restaurant and a pharmacy. At the time, it was the tallest building between El Paso and Fort Worth.

After 75 years of decay and decline, Brint Ryan and his wife Amanda set about renovating and fully restoring the iconic hotels rich history and beautiful 19th century Art Deco facade and interior opulence.

The scale model of Hotel Settles will be a permanent feature at the 2,500 sq. ft. operating model train exhibit in Frisco.

B&T Model Railroad is owned and operated by partners Bob Nunn and Tom Pantuso. They are joined by Tom’s son, Jeremy Pantuso, who worked tirelessly to engineer and assemble the final structure. The model itself was constructed using SLS 3D printing, mold and resin casting, CNC machining, and old fashion craftsmanship. Fort Worth artist Angie Glover provided the finishing touches, with exacting hand-painted detailing on the six-foot tall 1/32 scale model.

In February 2019 Bob LaPrelle, President and CEO of the Museum, reach out to B&T Model Railroad to commission the development and construction of the hotel model. Tom and his team began the long journey, scaling down the iconic West Texas hotel using the original architecture plans, on-site surveys, and Tom’s skills in creating exacting 3D models from sight.

Detailed designs and fabrication of the substrate, walls, and façade were accomplished using high-density foam, called Precision Board, from Coastal Enterprises.

A CNC machine from BOBSCNC accurately cut the nearly 500+ pieces required to duplicate the incredibly detailed Art Deco, brick walls, and ornamental features of the hotel.

Tom also incorporated the use of mold making and resin casting to create the more than 300 windows and doors that encompass the hotel.

Fort Worth artist Angie Glover brought her talents to the B&T family. She painted the entire building by hand, bringing to life each individual brick, hundreds of Art Deco panels and blocks, and capturing the beauty of the historic 1930’s building and all its glory.

LED lighting, combined with relays and independent power supplies, bring life to the Hotel Settles’ interior and exterior windows, floodlights, ceiling lamps, and wall sconces. The models lighting system works both independently and in conjunction with the exhibits own state-of-the-art lighting system.

After nearly ten months of research, design, fabrication, and detailing, the creative team at B&T Model Railroad, delivered the Hotel Settles in early November, where it will remain a permanent feature of the 2,500 sq. ft. TrainTopia Exhibit.

Sawatzky Blog: Adding Texture to Precision Board with a Die Grinder

Coastal Enterprises, manufacturers of Precision Board HDU, is proud to announce a series of guest blogs written by Dan Sawatzky of Imagination Corporation, which will be posted on the Precision Board Blog each month. This month Dan Sawatzky shows us how he quickly adds a hand-chiseled texture to Precision Board projects using an air-powered die grinder.  He says it adds value to their work while actually saving fabricating time!

In Dan’s own words…

One of the things we are renowned for is texture. We incorporate textures into almost everything we do. Texture creates a wonderful look and in our opinion is a way to add value to our work while actually saving us time in fabricating our creations. Even though we often use modern machines and tools, our work looks and feels hand-made.

A while back we created a sign for a chiropractor. I textured the good sized project using the method I describe below. On a whim I timed the process as I worked. The six foot by four foot sign took me about 18 minutes to accomplish the texture using an air-powered die grinder. When I delivered the sign the customer was extremely impressed I had textured the sides and back of the sign. As he gently rubbed his hand over the beautifully textured surface he commented to me that it must have taken FOREVER to accomplish the task. I smiled at him and said ‘You have no idea!’ He happily accepted his sign and paid his bill knowing he had received excellent value.

Most sign makers finish the sides and backs of their signs by sanding out every imperfection, filling any holes or dings and sanding some more as necessary. That’s perfectly fine as Precision Board sands easily. We take a different tact on most projects. Rather than sand things smooth, we instead deliberately introduce texture to these surfaces. I love the hand-chiseled look but I do it with a die grinder. It is a whole lot faster!

We are currently creating an order for a mini golf that had forty signs in all. With forty signs and three layers of Precision Board in each sign it made an impressive stack.

We routed the top 1” thick layer of Precision Board with a woodgrain texture and raised lettering and edges. The centre layer was 3/4″ thick PBLT-30 Precision Board HDU with a hole in the centre. We inserted a piece of 3/4″ plywood into these centre holes so we had something secure for our mounting screws (from the back). The third layer was another piece of 3/4″ 30lb Precision Board. I glued these layers together using PB Fast Set glue. To keep things together while the glue set up I used lots of clamps and a couple of screws in the corners to keep things aligned.

Once the glue was set I took off the clamps and fired up the die grinder. I did the top outer border first using random strokes to quickly take off just enough material to leave a texture.  Then I did the side edges before adding small quick 45 degree bevel to the top corner.

The backs of the signs were then textured and another small bevel on the back corner edge at a 45 degree angle. In less than two minutes this sign was ready for paint.

WARDJet: Waterjet Cutting of Precision Board HDU

Coastal Enterprises, manufacturer of Precision Board HDU, partnered with WARDJet to create a new sign for their corporate office.  The results are spectacular and were documented in a blog on their website, including settings information for their Z-Series waterjet.  Check out an excerpt and video below and then head to their website to read the full article.

Precision Board High Density Urethane (HDU), also known as Foam Board, is a popular material with many applications. In the video below, our Z-Series waterjet can be seen cutting a sign out of PBLT-34 Precision Board. This sign was then primed, painted, and mounted in the WARDJet boardroom.

Machine Settings

We used a .010” orifice and a .030” nozzle to cut the Precision Board. Additionally, we used 80 mesh GMA abrasive with an abrasive feed rate of ¾ lb/min. The sign was pre-pierced using a low-pressure, circular piercing method in order to reduce the likelihood of damage to the material. Full pressure (60,000 psi) was then used to cut the sign at a maximum speed of just 11ipm in order to maximize edge quality.

Creating Topographic Maps Worthy of the Royal Alberta Museum

Coastal Enterprises, manufacturers of Precision Board HDU, is proud to host guest blogs written by some of the signage industry’s biggest movers and shakers, posted to the Precision Board Blog.  This guest blog was written by Jason Hakki of Rapid Gantry in Prince Rupert, British Columbia, Canada.  He talks about machining topographic maps for the Royal Alberta Museum out of Precision Board urethane foam…and how he solved the challenge of routing a map with final dimensions that were too tall to fit within the Z height on his CNC machine.

In Jason Hakki’s own words…

Recently we were contracted by Royal Alberta Museum (RAM) to be part of creating exhibit pieces for their new museum for the Natural History Hall. Each of these topographic maps had their unique challenges and required collaboration between Rapid Gantry, other specialized contractors, and the incredible team of experts from RAM.

One of the models is painted entirely matt gray and is part of an interactive display where museum patrons can view snow accumulation/melt and the corresponding effects on ocean levels.

The second and largest model is a glacier cutaway showing a glacier and the landforms that glaciation leaves behind once they melt.

After much careful planning, design, and revision, we took our 3D CAD models and cut them using our large MultiCam CNC router. When selecting material we carefully chose PBLT-30 Precision Board high-density urethane (HDU) from Coastal Enterprises.

 

The feeds and speeds for these topographic maps were 300 IPM and 12,000 RPM.  The Precision Board HDU was cut with a 1/8″ tapered ballnose router bit from Tools Today. The cut time was around 18 hours on the big model and 10 or so on the smaller model. The smaller model exceeded my Z height, so it had to be cut as 3 separate slices which were then bonded together after cutting. The larger model was 11 feet long and 6.5 feet wide so it had to be cut in separate pieces and bonded in the end as well.

We applied a thick coat of TSF-45 high solids texture coat that we had tinted by our local paint store to match the design specifications.

Ultimately, we were able to successfully create two amazing exhibit models for the Royal Alberta Museum.

This was an incredible project and an incredible honor to be contracted by RAM not once, but twice, to create topographic maps for their new museum location.
