An Expanding Wooden Table

A few years ago, the world of fine woodworking was presented with the Fletcher Capstan table. It’s a round table, able to expand its diameter merely by rotating the top. A gloriously engineered bit of mechanics move the leaves of the tables out while simultaneously raising the inner part of the table. It’s a seriously cool table, very expensive, and something that will probably be found in museums 100 years from now.

[Scott Rumschlag] thought his woodworking skills were up to the task of creating one of these expanding tables and managed to build one in his workshop. Like the Fletcher Capstan table, it’s a table that increases its diameter simply by rotating the table top. Unlike the commercial offering, this one doesn’t cost as much as a car, and you can actually see the internal mechanism inside this table.

The top of [Scott]’s table is made of three pieces. The quarter-circle pieces are the only thing showing when the table is in its minimum position, and are arranged on the top of the ‘leaf stack’. When the table expands, four additional leaves move up from beneath with the help of a linear bearing made of wood and a roller that slides along the base of this mechanical contraption.

The center of the table – the star – is a bit more difficult to design. While the leaves move up the stack of table tops with the help of a ramp, this is an impractical solution for something so close to the center of the table. Instead of a ramp, [Scott] is using a lifting lever and metal hinge that brings the star of the table up to the right level. Even though it’s a crazy amount of woodworking and fine tuning to get everything right, it’s not too terribly difficult to get your head around.

Videos, including one of the assembly of the table, below.

A Modern Woodworking Workbench

This is a post about workbenches, but not the benches you’re probably thinking about. Workbenches meant for electronics development are simple matters – just about any flat surface, a few shelves for equipment, and an anti-static mat will be fine for every conceivable use.  Workbenches for woodworking are a separate matter entirely. There’s actually quite a bit of history behind the development of the woodworking workbench, but the basic idea is a thick laminated wood top, integrated vices, holes in the work surface for bench dogs, and ergonomics that allow for comfortable use of hand tools. The basic design of these benches hasn’t changed much in several hundred years, and [Dirk] thought the design was ready for a modern update.

Basement Wood-Drying Kiln

Once upon a time, a woodworker met another woodworker who happened to have a tree business. They struck a deal stating that the first woodworker would dry the sawn boards provided by the second and both would share the lumber. That’s exactly what happened to [Tim], which led to his entry in The Hackaday Prize.

[Tim] does a great job explaining his build of the kiln itself, his controls, and the gist of running the thing. The idea is to pull moisture out of the wood at just the right speed. Otherwise, the boards might check on the outside, honeycomb on the inside, or bear residual tension. He’s using a dehumidifier to pump dry air into the kiln and a control system to both monitor the relative humidity in the kiln and to dry the stock down to a moisture content in the 6-8% range.

kiln controlsThe kiln is built from slightly blemished pallet rack shelving that [Tim] cut to suit his needs. He skinned it with 1/2″ insulation boards sealed with aluminium tape and plans to add sheet metal to protect the insulation.

[Tim] wanted to control both a fan and the dehumidifier, monitor relative humidity in the kiln, log the data, and send it to the internets. For this, he has employed an Arduino Due, a DHT-22, an RTC, a relay board, an Ethernet shield, and an LCD to show what’s happening. The hardware is all working at this point, and the software is on its way. Check out his entry video below.


SpaceWrencherThis project is an official entry to The Hackaday Prize that sadly didn’t make the quarterfinal selection. It’s still a great project, and worthy of a Hackaday post on its own.

A Ring of Colored Pencils

Colored Pencil Ring

[Peter] proved he has equal parts prowess, patience, and perseverance with this colored pencil ring (imgur link). The ring is made from a cross-section of several colored pencils. The idea seems simple. The build process IS simple. As always though, the devil is in the details.

[Peter] started with a cheap pack of colored pencils. They have to be hexagonal pencils, as round ones won’t work well for this build. [Peter] used two nails to align the  pencils, and medium thickness Cyanoacrylate glue to bond them together. Cyanoacrylate (aka super glue) is a very strong but inflexible bond. We’re curious if a different adhesive might have worked better for this task.

Once the block of glued pencils was dry, [Peter] drilled a hole approximately his ring size. He used a band saw to cut a rough ring blank around the hole, then headed to the wood lathe. He mounted the ring with a jam chuck, which is a piece of wood turned to an interference fit with the workpiece. The problem was that the jam chuck cracked the ring as it was being installed. [Peter] was able to glue the ring back together, and turn it down on his lathe.

RFID RGB Lamp Goes the Distance

rfid-RGB-lamp

[Philippe Chrétien’s] project makes it to our front page just based on its completeness. When you hear about a multicolored lamp which changes based on an RFID tag you might not get too excited. When you look at the refined electronics and the quality of the wooden enclosure it’s another story entirely.

As we’ve said many times before, coming up with the idea for a project is the hardest part… especially when you just want to start hacking. With his kids in mind [Philippe] figured this would be something fun for them to play around with, opening the door to discussing the electronics concepts behind it.

He prototyped on a breadboard using three N-type MOSFETs to drive the colors of an RGB LED strip. The proven circuit was laid out and etched at home to arrive at the clean-looking Arduino shield shown off above. The entire thing gets a custom enclosure cut using layered plywood, a paper template, and a bandsaw.

Need a use for this once the novelty has worn off? Why not mod it to use as a motion activated night light? Alas the actual project link for that one is dead, but you get the idea.

Circular Saw to Table Saw Conversion

Corded circular saws are a dime-a-dozen at any old thrift store, yet table saws are a bit more of a costly investment — have you ever wondered if you could just make one out of a circular saw? [Matthias Wandel] did, and he just so happens to be very good at woodworking! He makes a lot of great woodworking videos to share on YouTube, and in his latest blog post, he shows us a rather elaborate way to convert a plain old circular saw, into a functional table saw.

While the concept seems simple, unless you do a lot of woodworking, you’ll probably marvel at how easily making things comes to [Matthias] — we know we did. By the end of the video he has a fully functional table saw that can raise and lower in height, and cut at different angles.

If you’re interested in making one yourself, he does a very thorough job explaining the process in his video — check it out after the break!

Family pulls together to build dad’s casket

build-your-own-casket

In these modern times we don’t often hear about families building their own caskets. But this project log documenting the deceased’s brother and sons fabricating a top of the line casket is really heartwarming. You may be thinking that they wouldn’t be able to include all the features you’d find on a commercially produced model. However, we remember seeing an episode of How It’s Made about caskets and there’s not much more than carpentry and simple upholstery involved.

The build starts with a plywood box lined with thin wooden ribs for added strength. The group then wrapped it with thin strips of dimensional lumber (maybe flooring?) which look great after a coat of stain. We’re not sure where the metal brackets for the two side rails came from. If you recognize them we’d love to hear about it in the comments.

The bottom line here is that for families used to working with their hands this is a great tribute and a way to commune with each other after the recent loss.
