Keeping those drinks within reach but also safe from spilling, I designed this Armchair Cup Tray.
Then I saw this Pin and I designed the Cup Tray to also fit across my bath.
Step 1: Concept, Parts & Tools
Most of my furniture is made from Oak, but for some time, I wanted to make something with Wenge. Mixing the two woods into one design creates a nice color contrast.
Parts - Materials
* 6mm or 8mm Triplex or similar Plywood : 190mm * 782mm
* 0.15 m2 of Wenge floorboards
* two pieces of 190 mm * 35 mm * 9mm Oak
* two pieces of 800 mm * 70 mm * 9mm Oak
Tip : if the parts are not cut accurately, just have them a bit larger. We will trim them down to exact measures using the router, yielding very smooth cuts.
Wood glue and Wood oil
* Saw (jigsaw and optionally crosscut)
* Sander (Belt-sander and/or Orbital sander)
Step 2: Building the Floorboard
In my case the base is 190 mm wide (as this fits to the width of the armrest of my sofa), and the Wenge parts are 300mm long.
So I cut a first Wenge part to just a little more than 190 mm, and glue it on the base.
Then I glue the remainder at the second row.
Then I take the next Wenge stick to continue on the second row.
Tip : make sure that all the cuts which are in the middle of the base, are nice and square. Otherwise you will get some gaps.
The cuts at either end are not so important, as the wood will be trimmed down in a next step
After the board is completely glued and dry, it is a good idea to sand the surface of it now. Later we will glue sides onto the board, and sanding will be more difficult. With the belt sander, in the direction of the grain, sand until you have a smooth surface.
Tip : If you have still some gaps in the board, you can use a mix of wood glue and sand-dust to fill them up.
Warning : according to WikiPedia, the dust from Wenge is sligthly aggresive, so take protection using a dust mask and or gloves.
Finally we need the board to be trimmed down to its final dimensions, cutting away all excess.
It is difficult to cut and glue all the floorboard pieces at 100% exact length, so I ususally make them a little bit longer (a few mm), and then use a saw or router to trim them down to exact measures.
In order to trim along a nice straight line, I used a piece of Aluminum (an L-profile) : Clamp it to the floorboard. Then use the router with a straight bit to trim it down.
Step 3: Adding the Sides
I decided to make this little border 6 mm high.
In order to get an exact 6 mm all around, here is a simple trick :
* put a scrap piece of 6 mm MDF on the workmate,
* put the base onto it, face down
* glue the side (side is not resting on the MDF piece.)
After glueing the two short side, trim them down with the router or sander as well.
Then glue the long sides. Use again a piece of 6mm wood, to check for a consistent border around the piece.
Tip : I noticed that after glueing the Wenge onto the triplex, the whole base was no longer flat. Apparently the Wenge wood was more alive than the triplex. So I put clamps at the long ends first, then flattened the piece towards the center, and put 3 additional clamps there.
After the long sides have been glued (and dried), use your Jig Saw to cut an S-shape at the end.
I cut a scrap piece into this shape first, then using this as a template, you can have the same shape at all 4 ends.
You could do this even better with the router, but I didn't have the right bit for it.
Step 4: Finishing Touch
By hand, sand down the edges until they are no longer sharp.
Apply wood oil.
I did NOT apply oil to the bottom side, as this side will touch the fabric of the sofa, and may get greasy from the oil.
