Building a Train Collector’s Ultimate Display

(Custom Furniture Denver, Colorado Metro area) — Today, my workshop isn’t just a place of sawdust and lumber; it’s a train station of sorts. I’m building a custom shelf for a dedicated model train collector, but before I even milled the first board, I needed inspiration. So, I journeyed out to the Colorado Mining Museum to see an old steam engine in action. The raw, mechanical power of that thing was pretty wild. It inspired me to create something with the same spirit of craftsmanship.

Back in the shop, with the sound of that steam whistle still echoing in my mind, I began. I started by milling the walnut lumber and cutting all the pieces to length. The custom shelf design called for the shelves to attach to their vertical supports using a combination of a half-lap joint and a bridle joint—a strong, classic combination worthy of a locomotive.

To ensure precision, I built a custom jig to the exact thickness of the shelf. Using a pattern bit in my router, I used this jig to route out the bridle joints. The beauty of this jig was its dual purpose: its sides were the same width as the space between the shelves, allowing me to use it as a guide to place each shelf in the exact spot on both vertical supports. This guaranteed that everything would line up perfectly later. After routing, I used the jig to square up the corners left by the round bit before moving the setup to the next position.

With the dados routed on one side, the challenge was mirroring their location perfectly onto the other. Since a half-lap joint would bridge the gap between them, precision was non-negotiable. I used the pattern bit to start a registration spot, then dropped in a piece of wood to act as a new stop for my jig to cut the mirror-image dados on the opposite side. It was a satisfying puzzle.

Next was creating the half-lap portion of the joint. To avoid routing too far, I cut and secured some spacers in place before heading to the router table to clean out all the spaces. Even with each shelf having a different offset, I used a stop block on my miter gauge for stability and safety. The real key to alignment was a simple plywood “story stick.” I cut two notches in it, representing the distance between the vertical supports, and I used that to set the stop block for each of the three shelves. Without it, the whole assembly would be crooked.

At this point, a test fit was essential. Seeing it all slot together, just as planned, was a major relief. While it was assembled, I built another quick jig to route mortises for floating tenons, adding crucial strength across the supports where I’d removed material for the shelves. This jig simply clipped over the shelves and around the supports. With a plunge router and a guide collar, I worked my way around each joint.

I also routed out a slot in the center of each support for a French cleat—the hidden hardware that would eventually hang this entire piece on the wall. I made sure to save this jig; on the job site, I can hold it up to the wall to mark the exact location for the mating cleat, ensuring a perfectly level installation. After routing, I squared the end of each slot with a chisel, a small hand-tool detail that makes all the difference.

With the joinery done, it was time for the fun, decorative details. I wanted the front supports to have soft arches, evoking the entrance to a mountain tunnel. I shaped a template on the bandsaw, hand-sanded it smooth, and then used it with a flush trim bit at the router table to shape the actual pieces after rough-cutting them on the bandsaw.

The pièce de résistance was cutting the hole for the train tunnel itself. I created a final plywood template for the tunnel shape, removed most of the waste at the drill press, and did the final trim pass at the router table. For a small trim piece around the tunnel, I programmed my compact CNC to make the precise cut my old, broken scroll saw couldn’t handle.

Installing that trim piece required one more clever trick: I dropped a piece of scrap wood into the shelf slot to help line up the bottom edge of the trim piece as I glued it in place. I’d cut it oversized intentionally, so once the glue was dry, I simply flushed it off at the router table for a perfect fit.

Then came the moment of truth: the final glue-up. With so many parts, I opted for epoxy to give me plenty of working time. As I clamped it all together, the shelf finally took its true form. I cut the floating tenons and French cleats from some spare stock, rounded over the tenons’ edges for easy insertion, and got ready for the final assembly.

I glued and screwed the French cleat into its slot, setting its mate aside for the installation. Then, I glued all my floating tenons into their mortises, locking the entire structure into a single, incredibly strong unit.

A few coats of polyurethane brought out the richness of the wood. Hanging it on my client’s wall was the final step. We ended up with more than a shelf; we created a display that doesn’t just hold a train—it interacts with it, becoming a part of its story. And that’s a project worth building.
