The roots (pun intended) of an individual piece are born before the wood ever reaches our shop. While we have always preferred locally-sourced black walnut, we also deal with wood of many species from across the nation. Many are trees that are decades or centuries old, and their legacy continues when they are cut into slabs which we then use for our products and sell directly to customers.

Once the wood is milled into the illustrious slabs, it is considered "green" and has to be air-dried. Due to the semi-arid climate of southern Idaho, this typically takes about a year/inch, for example, a 3-inch thick slab would take 3 years to dry. During this process, the wood checks (cracks) as it is drying. It is crucial to properly dry wood so that it does not continue to crack or split once it has been made into a product.

After the wood is dry enough, it then goes through a process known as "kilning". The wood is placed in a wood kiln, an isolated chamber where the wood is exposed to extreme heat. This kills off any bugs, insects, or eggs that may be hidden within the wood. Kilned and non-kilned wood are always kept separate - if cross-contamination occurs, bugs could get into the clean wood!

Finally, the wood is ready to be used in the shop. The slabs are run through our 52" wide belt sander for flattening, then set aside until used for a project.

Once a slab is selected for use, the bark is removed as it's extremely difficult to work with. It is then laid out and designs are drawn an proposed for a layout. Some slabs are cut and the live edges become the outline of the river, but the design is always unique and wood can be oriented every which way to make the perfect piece come together. 

Once the layout is approved, it is then molded up in our pour room. The pieces are laid on a table and clamped into place and/or weighed down to keep the design from shifting. Resin is comparable to water in it's pre-cure state, so every possible leak point and crack has to be sealed in order to prevent the resin from escaping!

We use a variety of materials to make this possible. The pour table surface is made of a thick sheet of High-density polyurethane (HDPE), which prevents the resin from absorbing into the table surface.

• HDPE is one of the few materials that epoxy cannot penetrate!

We use starbond, a fast-drying super glue, to keep our wood islands from floating in the resin river. We use silicone to seal the outer edges and seams. It takes silicone about a day to cure, so molding up a large piece can take 2 or more days. Despite all that prep, leaks are still common so we keep an eye on fresh molds.

When the table is ready, we then mix up our resin. The thick-pour epoxy we use is mixed in a ratio of 2 parts resin to 1 part hardener. We are able to pour around 2½" thick, so each mold can be done in a single pour. The epoxy is crystal clear, so we mix in metallic pigment flakes specifically engineered to suspend in the resin, giving it a sense of depth and unmistakably beautiful element. For solid colors, we use a liquid pigment instead.

We pour as much as the crest of the river will allow and let it cure. Typically, the resin infiltrates and absorbs into the wood, and we have to watch it, not only for leaks but to top it up as needed. Once we're confident, we let it be. With the amounts of epoxy we use, it takes about 3 days to cure.

While the resin absorbs into the wood while curing, that's not the only thing it does. There is a lot of science that happens completely unseen during this time. Bubbles are a common sight. This can come from places where there may be a hole in the wood, and the resin hardens as it fills that space, trapping bubbles in it. Static electricity is also a key contributor to bubbles, which comes from the HDPE plastics. We are innovating to reduce or eliminate the static issue entirely. 

The curing is an exothermic chemical reaction and as such, the resin can get very hot during the process. This temperature usually is for the better- it creates updrafts and downdraft cycles within the epoxy itself, as it rises and cools, then sinks and heats again. This internal current takes the pigment with it, creating the breathtaking designs and swirls all on its own. 

Once the resin is finally cured, we then remove the mold from the table. larger pieces can take 2 or 3 people to carry out of the pour room!

We remove excess bits of epoxy and silicone on the edges, then send the hardened piece through the wide-belt sander once more. The wood and resin thicknesses vary greatly, so the whole piece is flattened some until the surface is uniform. 

Next, if there are any bubbles, holes or voids the resin didn't manage to fill, we use UVPoxy from ecopoxy, which cures much quicker (24h). This can take several hours just to fill each spot, depending on the depth and number of cavities. The spots are then sanded down with orbital sanders. The Wide-Belt only outputs a grit around 80, so the piece has to be sanded multiple times, each time with a higher grit level. Often, pieces are sanded 4 or 5 times until sanded with 320-grit sandpaper, at which point the surface is smooth enough to properly show the details in the wood.

Alongside this production queue, we outsource our legs from local welders. The designs are fabricated and painted as needed, then dropped off at our shop. We align the bolts so that they anchor in the wood and are not seen in the resin, then install the legs securely using as many bolts as will securely hold the table in place. Large or heavy pieces have additional reinforcement to keep the table from bowing, including rails or even a center leg. 

The piece is still murky from the sanding, but once we oil it, it springs to life. We use osmo finishes which affect the final tone of the surface. We start with a water-resistant penetrating layer, then the finishing coat which can apply a matte, satin, or gloss look to the piece. Finally, we top the piece with a ceramic coating that provides superior durability while also making the details pop.

Each coat takes about 8 hours to dry, so the post-sanding process takes at least 2 days to perform.

With the final coat applied and cured, the piece is ready to go! Spec furniture stays in the showroom and is listed online, while custom projects are either delivered locally or shipped. We thank you for you business and include a care kit with every purchase.
