Door hidden by bookcase is a marvel of DIY engineering

Taking on a giant build just to hide your shotgun collection may seem a bit over the top. But we couldn’t be more impressed with the project. [Korostelevm] did an amazing job of hiding a small closet with a bookcase-door. It’s something straight out of a Hardy Boys novel.

Possibly the most important part of the build is figuring out how to hinge all the weight a bookcase will carry. His solution was to use a set of four heavy-duty casters. He cut off the wheels from one pair and the mounting brackets from another. By welding the brackets on in place of the wheels he has a sturdy way to mount both the frame and the bookcase. When closed the unit latches using a strike plate and lock set from a door. This is connected to a book using some cabling and pulleys. As you’d expect, just find the right hard-cover and tilt it toward you to open the hidden storage behind. [Korostelevm] shows off the final product after the jump.

Building your own router lift-out mechanism

Adjusting the bit height on a router table can be a pain in the butt. Traditionally you needed to get into the cavity under the table top in order to make these adjustments, and it’s hard to make the adjustment and measure the height at the same time. Modern routers now offer the option to adjust height through a hole in the plate that sits in the router table, but this is usually only found on the more expensive models. Rather than buy a new tool [Urant] built his own router lift.

He’s using recycled closet rails to give his rig some smooth operation. These are the rails and runners that let closet doors hang from the top jamb. He saved them when replacing the closet doors in one of his rooms. There’s a triangular gantry which hosts the router, allowing it to move vertically on the three sets of rails. The threaded rod in the foreground of the picture above lets the woodworker adjust bit height by turning the nut at the top. Once mounted in the router table the nut is accessible through a small hole in the table surface.

Converting from clutter closet to dreamy datacenter

[DocDawning] had a nice home network up and running, but the messy pit housing the hardware made him avoid that part of the house. In an effort to cut down on noise, and clean up the clutter, he built himself a very nice data center inside a small closet.

One of the biggest changes in the setup provides adequate cooling. He cut a vent hole into a wall shared between the closet and a hallway. This was just the right size for a few large cooling fans which suck air into the enclosed space. But cool-air intake must be accompanied by hot-air outflow so he added an exhaust vent in the ceiling. This also received a trio of big fans, and as you can see above, the integrated LEDs act as a light source for the server farm.

The final part of the plan involved machine-specific brackets mounted to the walls of the enclosure. These racks were built out of 1×1 white wood. They hold the hardware in place leaving plenty of room to run cables. The new setup even opened up enough wall space to mount power and networking hardware. Now everything has its place, and [DocDawning] can finally close the door on his noisy servers.
