I wanted more space on the counter, so I made an over-the-sink dishrack. The prototype was my conventional metal dishrack screwed to the wall and cabinet.
I wanted to use a branch I had lying around for the front support to make it look more interesting.
Step 1: Attaching the branch to a plank makes it easier to drill - part 1
The front of the new dishrack was made from a branch. I needed to drill a row of holes to hold the rods so that they would be parallel and form a straight, flat surface. First, I supported it with scraps of wood so that the side I wanted the rods in pointed straight up.
Step 2: Attaching the branch to a plank makes it easier to drill - part 2
To keep the branch from rocking or twisting when drilling, I attached it to a plank of wood. First I put a screw through the left end. I didn't mind the hole because the last few inches of the branch would later be cut off to make it fit between the cabinets. On the right end I used screws to pull a chain very tight over the top of the branch. Clamps were not an option since the plank would need to slide freely on the drill press table.
Step 3: Getting ready to drill - part 1
I clamped a board to the drill press table to serve as a guide. This made sure the holes I drilled were all in a line.
Step 4: Getting ready to drill - part 2
I wanted the holes to be spaced at ~3/4" intervals so I used a tape measure and a mark on the drill press table to know where to drill. To keep my hands free for more important things, I clamped the body of a tape measure to the drill press table and stapled the end of the tape to the board supporting the branch. As shown in the quick video, the tape would move with the branch, which let me count off 3/4" intervals.
