Crank-Powered Train Uses No Batteries Or Plugs

April 12, 2024 by 5 Comments

The prolific [Peter Waldraff] is at back it with another gorgeous micro train layout. This time, there are no plugs and no batteries. And although it’s crank-powered, it can run on its own with the flip of a switch. How? With a supercapacitor, of course.

The crank handle is connected a 50 RPM motor that acts as a generator, producing the voltage necessary to both power the train and charge up the supercapacitor. As you’ll see in the video below, [Peter] only has to move the train back and forth about two or three times before he’s able to flip the switch and watch it run between the gem mine and the cliff by itself.

The supercapacitor also lights up the gem mine to show off the toiling dwarfs, and there’s a couple of reed switches at either end of the track and a relay that handles the auto-reverse capability. Be sure to stick around to the second half of the video where [Peter] shows how he built this entire thing — the box, the layout, and the circuit.

Ballpoint Switch Is Oh-So Satisfying

January 28, 2024 by 8 Comments

Alright, here’s your quick and dirty hack for the day. The astute among you may recall [Peter Waldraff]’s bookshelf train build of a few days ago, and the fact that he used a switch made from a dead ballpoint pen to light up the scene. Fortunately, [Peter] wrote in to give us the details of this low-voltage sub-build, which you can see in the video after the break.

Essentially, [Peter] starts by making a shortened version of the pen. He modifies nearly every bit of it, including cutting down the ink cartridge, so if you try this, make sure the thing is all dried up first. Then, as he is screwing the point holder back on the barrel, he wraps elastic cord around the inside barrel in lieu of having sewing thread lying around. This cord along with some hot glue will hold a pair of paper clips to the sides of the point holder. When the pen is clicked into the writing position, it makes a connection between the paper clips and closes the circuit on whatever is wired into it.

What types of little hacks like this have gotten you through the build? Let us know in the comments, or better yet, write it up and drop us a tip. By the way, here is that bookshelf train build in case you missed it.

Is This The World’s Smallest N-Scale Train Layout?

January 23, 2024 by 7 Comments

There’s just something about miniature worlds — they’re just so relaxing to look at and ponder. Think you don’t have ample room for a model train layout at your place? You may not be thinking small enough. [Peter Waldraff] knows a thing or two about hiding train layouts inside of furniture (that’s one solution), but this time, he’s built a track in plain sight that’s meant to sit on the bookshelf. The whole thing is just 5.5″ x 12″.

This N-scale layout was three years in the making, mostly because [Peter] was waiting for just the right little powered chassis to come along. For the layout, [Peter] started by creating custom flexible track by removing pieces with a sharp knife. He glued down the track to pink foam and used nails to hold it in place while the glue dried. He also built a wood frame around the base to stabilize it and hold some of the electronic components, including a switch made from an old ballpoint pen.

Then it was time to start decorating the thing, beginning with a couple of buildings made from more pink foam that are both lit up with LEDs. Eventually, [Peter] added a bunch of details like streetlights, animals, and garbage cans that really make the layout pop. As far as the engine goes, [Peter] picked up a Tomytec TM-TR02 on eBay and built a trolley out of two broken cars. [Peter]’s build is something you just have to see for yourself — fortunately for you, the build and demo video is after the break.

Like we said, [Peter]’s usual territory is hiding train layouts in end tables and coffee tables and the like, so it’s nice to see what he can do given different constraints.

A Concealed Model Railway Rises To The Occasion

December 13, 2022 by 5 Comments

Occasional pieces of furniture serve little purpose other than to fill a space and maybe display a prized ornament or two. Who hasn’t got a relative with one two many small tables or display stands overfilling the available space!

If you visit [Peter Waldraff]’s house though, those pieces of furniture may not be what they seem. His display pedestal for example hides an N gauge railway layout that rises from the depths on a system of pulleys, with the action triggered by moving the vase displayed on its top. The vase conceals a magnet, which operates a reed switch that in turn controls the winch motor.

The layout is a loosely Batman themed train chase, with concentric spirals of track forming a continuous loop on which two trains run. There’s an ingenious arrangement with a reed switch and a piece of dead track to ensure that the chasing train is always held to ensure a gap between them. The landscaping is of a set of cliffs with a model of Wayne manor at the top, and there’s even a LED-lit Batmobile. One of the locomotives is recognisably based on a character from the Thomas the Tank Engine books.

All in all we like the ingenuity of this layout, but if you like it too then we’ve got a treat for you. Sharp-eyed readers will remember that this isn’t the first such project from Peter.

This End Table Conceals A Close Encounter

April 11, 2022 by 18 Comments

If you’re of a Certain Age, perhaps you had a train set as a child. An oval of track, a loco, and some rolling stock; it matters not whether it was Thomas the Tank Engine or a large express train — they were at the time a pretty cool toy. Move forward a few decades, and model railways have become either super-expensive room-filler layouts, or have sunk low as novelty Christmas ornaments, so that the basic loop of track is in dire need of rescue. Perhaps [Peter Waldraff] can help, with a beautifully-constructed N gauge circular layout concealed in an end table. Even better, when you examine it closely, it becomes apparent that this is no ordinary train set, it’s a scene from Close Encounters Of The Third Kind.

This is a project of two equally well-made parts, the piece of furniture and the train. The former is entirely scratch-built, with a cylindrical outside made from carefully cut rings of plywood and a sliding riser mechanism in the centre with a concrete counterweight. Slide the cylinder upwards, and the layout is revealed — a scratch-built hill in the centre of the ring of track and the lit-up underside of the UFO above it. As the train goes round the track, it even triggers a set of crossing lights and sounds for extra realism. The full story can be seen in the video below the break, and is well worth a watch.

We’ve covered more than one concealed model railway layout in the past, and it comes as no surprise when browsing to find that [Peter]’s work has featured here before.

N-scale model railroad hidden in wall art

Hidden Model Railroading Taken To The Nth Scale

January 6, 2022 by 6 Comments

Most of us would be pretty happy with ourselves if we made one of those neat “epoxy river” types of art for our home. Not so with prolific maker [Peter Waldraff]. [Peter] is a skilled craftsman with a penchant for hiding model railroads in everyday furniture and fixtures. To this end, he’s created what he calls the Hidden Epoxy Railroad, which you can see in the video below the break.

The project starts with basic woodworking to build the frame, hinges, and the hinged epoxy river with its colored epoxy pour. Instead of stopping there, [Pete] continued by building a full N scale model railroad into the piece. The frame doubles as a backdrop complete with a beautifully painted scene with what we’re guessing is an N scale hot air balloon, too.

Of course, the skeptics among us might doubt whether the model railroad is fully hidden when closed. But one detail that Pete shared with us is that his wife never knew about the train portion of the build until their daughter pointed it out. She thought it was merely a piece of art for the dining room. Truly a great hack!

The entire build is documented on [Pete]’s YouTube channel, with its own 15 part build series. It’s definitely worth checking out. We’ve covered one of [Pete]’s hidden railroad builds before, so make sure you check that out, too!

Swiss Army Knife Of Power Tool Carts

January 2, 2022 by 9 Comments

When you’re into woodworking in a serious way, you’re going to eventually want some power tools. With such efficiency of operation, things can go pear-shaped quickly, with wood dust getting absolutely everywhere. It’s not always practical (or desirable) to work outdoors, and many of us only have small workshops to do our making in. But woodworking tools eat space quickly. Centralized extraction is one solution, but all that fixed rigid ducting forces one to fix the tool locations, which isn’t always a good thing. Moveable tool carts are nothing new, we’ve seen many solutions over the years, but this build by [Peter Waldraff] is rather slick (video embedded below,) includes some really nice features in a very compact — and critically — moveable format.

By repurposing older cabinets, [Peter] demonstrates some real upcycling, with little going to waste and the end result looks great too! There is a centralized M-Class (we guess) dust extractor with a removable vacuum pipe which is easily removed to hook up to the smaller hand-held tools. These are hidden in a section near the flip-up planer, ready for action. An auto-start switch for the small dust extractor is wired-in to the smaller tools to add a little ease of use while reducing the likelihood of forgetting to switch it on. We’ve all done that.

For the semi-fixed larger tools, such as the miter and table saws, a separate, higher flow rate moveable dust extractor can be wheeled over and hooked up to the integrated plenum chamber, which grabs the higher volume of dust and chips produced.

A nice touch was to mount the miter saw section on sliding rails.  This allows the whole assembly to slide sideways a little, giving more available width at the table saw for ripping wider sheets. With another little tweak of some latches, the whole miter section can flip over, providing even more access to the table saw, or just a small workbench! Cracking stuff!

Need some help getting good with wood, [Eric Strebel] has some great tips for you! And if you’re needs are simpler and smaller, much much smaller, here’s a finger-sized plane for you.
