I have a Synology DiskStation (DS209j) that I use on a primarily Windows network, but in some cases I want to access the DS shares from Ubuntu virtual machine running inside VirtualBox. There’s no sense mounting them as Windows shares with the DS supports NFS, so I went that route in stead. (Besides, some application still have trouble with Samba shares.)

I was scratching my head over a “access denied by server while mounting” error until I realized that VirtualBox was getting in the way. Here are the steps I took to get it up and running properly:

  1. In the VirtualBox menu of the virtual machine , select Devices > Network Adapters… and choose Bridge Adapter instead of the default NAT. This takes your virtual machine out of the private network it has with the host computer and makes it a first-class citizen on the network your host computer is on, with its own IP address.
  2. Check the guest machine’s IP address by opening Applications > Accessories > Terminal and typing “ipconfig”. It will probably start with “192.168″, but you’ll need all four parts if you want to limit access to just that machine.
  3. Log into Synology DiskStation Manager as admin, and click Management.
    1. Under Information, click Status and note the network IP address of your DiskStation. It will probably start with “192.168″, but you’ll need all four parts of the IP address.
    2. Under File Sharing, click NFS, and make sure it’s enabled.
    3. Under Privileges, click Shared Folder. Select the folder one you want to mount using NFS, and click NFS Privileges at the top of the list to add a new privilege. Use the IP address of the guess machine to lock access down to that specific machine, or use wildcards to allow access accross your local network (e.g. “192.168.*.*”).
    4. Before you close the NFS Privileges window, note the “Mount path” at the bottom of the list. It will probably look something like “/volume1/MyShare”
  4. To automatically mount the NFS share when you start up, go back to the Terminal window on the guest machine.
    1. Create a directory to use as a mount location. For example if you want to use “MyDSData” in your home folder, type “sudo mkdir /home/YourUserName/MyDSData”. Enter your password when prompted.
    2. Type “sudo gedit /etc/fstab” in the same Terminal window, and edit then add the line below  line to the end of the file. (It’s all one line.) Instead of “[DS IP Address]” use the IP address of your Synology DS, instead of “[Mount path]” type the mount pah, and instead of [Mount location] type the directory you made above. Don’t leave out the colon or the spaces.

      [DS IP Address]:[Mount path] [Mount location] nfs rw,hard,intr,nolock,nfsvers=3 0 0

      For example: “192.168.1.42:/volume1/MyShare /home/alex/MyDDData nfs rw,hard,intr,nolock,nfsvers=3 0 0″

Here’s a video that explains how to use the custom branding irons to burn your brand on woodworking projects. The branding irons were originally described in A $6 Custom Branding Iron, and there is a tutorial at Making the $6 Branding Iron, Step-by-Step.

First, create a shared folder using the VirtualBox user interface. For this example, we’ll call it “Data”. Launch Ubuntu.

From within Ubuntu, launch Application > Accessories > Terminal, and at the prompt type

sudo gedit /etc/fstab

Enter your administrative password, and you’ll see a text editor window appear with the fstab file loaded. Add the following single line to the end of the file, but replace “username” with your actual username.

Data /home/username/MyData vboxsf defaults,rw,uid=1000,gid=1000 0 0

Click “Save” and then restart Ubuntu.

Once restarted, go to Places > Home Folder and note the new MyData folder. This is your shared fol

In the A $6 Custom Branding Iron post, I showed off a branding iron I had “printed” in stainless steel by Shapeways.com for US$6, after using the free vector image editor Inkscape, and parametric modeling software Alibre Design, which also has a free version called Alibre Design Xpress.

This tutorial requires a working knowledge of Alibre Design (or other 3D parametric modeling software) and Inkscape (or other vector graphics editing software).

Here are the steps I took to make it happen: (I’ll add more detail over time.)

  • Design in Inkscape
    1. Convert all text objects to paths (Path > Object to path)
    2. Convert all stroked lines to paths (Path > Stroke to path)
    3. Ungroup all objects
    4. Union all objects (Path > Union)
    5. Select object
    6. Save As… Type Desktop Cutting Plotter (R13) (*.dfx) – Output will be in mm
  • Import into Alibre Design (File > Import, type DXF)
    1. Select mm for file units
    2. (It imports into a drawing)
    3. Select everything and Explode (Edit > Explode Symbol)
    4. Activate the sketch
    5. Analyze (Sketch > Analyze…)
    6. Heal all problems
    7. While activated, select the figures
  • Copy to a Alibre Design Part
    1. Open a new part
    2. Activate a design plane and Paste (the figure may appear far from center)
    3. Select the curves, shift-left-click to drag to better location
  • Model the branding iron
    1. Extrude sketch 1.25mm — this is the depth of the brand.
    2. Select *top* face and insert a plane. (right-click > Insert Plane…)
    3. Select the new plane, Project to Sketch (if necessary), to create a foundation for the brand.
    4. Extrude 2mm for foundation
    5. Insert another plane on the back of the foundation
    6. Extrude a mounting hole, 4.9mm is 0.1375mm larger than 3/16″
    7. Cut a set screw hole in an accessible location if necessary. 3.048mm is 0.12″, the tap size for #6-40 set screw.
  • Export & Upload
    1. Export as *.STL file
    2. Upload to Shapeways.com
    3. Order in stainless steel
  • Finish
    1. Tap the mounting flange for a 10-32 screw
    2. Thread a 3/8″ steel rod with 10-32 die or use a 10-32 screw
    3. Build a handle
    4. Sand down the surface of the branding iron to make it nice and flat

This is Part 3 of a 15-page tutorial (in three parts) that will show you how to build an heirloom-quality, all-wood chess or checkers board with just a few small pieces of lumber. (Use the page navigation at the bottom of each post to change pages within each part.)

This part covers cutting the inlay through finishing. You can also:

  • Go back to Part 1 (6 pages), which covers planning through first layer glue-up.
  • Go back to Part 2 (5 pages), which covers cutting the squares through planning this inlay.

Cutting the Inlay

Now it’s time to cut the top inside edges of the frame boards to accept the inlay. Fortunately you don’t really need to do any measuring here. We’ll be cutting a groove in the frame for the inlay, and we’ll set the router using the inlay pieces we’ve already prepared. Insert a straight bit into your router, and set the depth to lower than the shortest of your four inlay pieces. In the photo below, I have all four pieces lined up from shortest to tallest, and the bit is set slightly lower than the one in front.

Set the router table fence so that the blade will cut slightly shallower than the thinnest of the inlay pieces. This will be the final width of the inlay on the finished chess board. In the photo below, you can see that the fence is set up so that the router bit would cut into the tiny inlay piece, but not though it.

Setting the width of the inlay

Setting the width of the inlay

Use a piece of scrap lumber to test the router and table settings. None of the inlay pieces should fit all the way in the grove your router cuts – they should all be just a bit too wide and just a bit too long. This is what you want. Now carefully cut the groove to receive the inlay along the top inside edge of each frame piece. I didn’t take a picture of this part because I was being careful not to cut my fingers off.”

This part covers cutting the squares through planning this inlay. You can also:

  • Go back to Part 1 (6 pages), which covers planning through first layer glue-up.
  • Skip to Part 3 (4 pages), which covers cutting the inlay through finishing.

Cutting the Squares

Now it’s time to cut the squares. Start by trimming one edge of the board so that it is perfectly perpendicular to the first slice you glued down. Take off only as much material as you need to make the ends of the slices flush with the edge of the board. I use a shop-made crosscut sled for this.

Next, measure the width of the stripes carefully, and add a stop block to the crosscut sled (or set your table saw fence) so that when you cut across the stripes, you’ll end up with pieces exactly the same width as the stripes themselves – 2 inches in this example. (See photo below.) Write the numbers 1 through 8 across one of the light stripes so you’ll know the order in which you made the cuts. You can see the numbers (albeit faintly) in the image below written on the second light stripe from the bottom. The numbers go from right to left. Measure again, take a deep breath, measure again, and then cut your first strip.

You’re going to be slowly cutting away at the nice long straight edge that you started with, so it’s a good idea to draw a reference line on the sled indicating the width of the pieces you’re cutting . . . better safe than sorry.

Be sure to check for sawdust next to the stop block between each cut. (See photo.) Dust and splinters here can result in unequal widths – something you definitely want to avoid when making a chess board.

Continue cutting until you have eight strips of the same length and width. Make the last cut carefully and use a ruler or the alignment line you drew onto the crosscut sled.

You’ll end up with eight pieces, each exactly two inches wide. Note in the photo that the backer board extends a little further than the walnut square. This is okay because it’ll be trimmed off a little later.

This is a great project for using up some small, otherwise unusable pieces of wood you may have laying around your shop. It’s very easy to build even with woodworking hobbyist tools, and it doesn’t consume a lot of expensive wood. The method described here will result in a handsome board with perfectly aligned squares, a sophisticated (but simple) inlay, and a polished finish.
