This is how I made the kitchen sink for the kitchen room box. I made the sink from wood, gesso and a jelly container, the small single serve kind from restaurants. If that's not available I've used any "bubble" packaging that is the size of the sink I want, this one being 1 1/2" x 1 3/4".
Start out with a piece of 1/16" thick stock, 1 7/8" x 4 1/2". Cut a hole in the center for your sink. I am now going to refer to this piece as the sink top. The plastic bubble should have a flange that you can use to glue the "sink" onto the wood. I glue the "sink" under the top. Don't glue now, just don't trim this flange off. Measure the sink and cut the opening, 3/8" from the back and 1/8" from the front. You can use an exacto knife, cutting a little bit at a time. Sand smooth.
We are going to add onto the 1/16" x 4 1/2" x 1 7/8"piece, the sink top, by gluing more wood to the top of it to make it thicker for the edge, back of top and drain board ridges.
From 3/32" stock cut a strip 3/8 wide and 4 1/2" long. Soften one edge of this piece, it should not be square, diagram A. This piece is glued toward the back on the of the sink top. This is where the faucet will be glued on. Glue the strip on using wood glue and clamp.
From 3/32" stock cut a strip 1/8" wide and 4 1/2" long, also cut 2 strips 1/8" wide and 1 3/4" long. Soften the top 2 edges of these 3 pieces, diagram B. Glue these pieces onto the sink top according to diagram C. Clamp and let dry. When dry slightly round off the front 2 corners of the sink top.
When everything is dry I sanded a slight slope to the drain boards going toward the sink.
Cut from 3/32" stock 1/16" wide strips. ( If you have access to 1/16" half round use that.) Round off the top 2 edges of the 3/32" x 1/16" strips according to diagram B. These are the drain board ridges. I glued 6 of these onto each side of sink. You'll need to clamp these down if you sanded the slope in.
Before you glue the sink to the underneath side of the sink top, cut a hole in the center for your drain. I found a plastic cap about 1/4" in diameter. I cut it off at about a 1/4" and stuck a straight pin in the center, painted it silver and dotted it with black on the inside of the cap to simulate the drain holes. This became my sink strainer/basket.
Another option is to use a gripper snap for the rim and leave out the strainer/basket. Gripper snaps are found in the notions department of a fabric store.
When you are satisfied with all of your sanding, glue the sink to the underneath side of the sink top, and set this assembly aside.
Cabinet. Follow the sizes in the diagram for cutting out the sink sides, back and front. Round off the top 2 corners of the back. Glue the sides onto the back, bottoms even, the back will be 3/8" taller, that's the back splash.
Glue the front onto the sides, keep the tops even. Follow the drawing at the top of page.
Cut from 1/16" stock a strip 3/8" x 4 3/8", this is to be painted black and will be glued onto the bottom front of the cabinet, it's the back of the toe kick.
The doors are made from 1/16" stock, cut 1" x 1 3/4", cut 4.
The drawers are 1/16" x 1" x 1/2", cut 2
The center vent is 1/16" x 1 1/16" x 1/2", cut 1.
With sand paper soften all four edges of the doors, drawers and vent.
I cut vent slots with an exacto knife. I've also seen a shape cut out and filled with decorative screen, maybe paper with tiny holes punched into it, or cross stitcher's perforated paper.
Glue sink top onto cabinet. The sink top will be longer and wider than the cabinet by just a bit, center the cabinet under the sink top from side to side and it should have extra in the front.
I use gesso to smooth everything in, all the seams need to be filled. I paint the whole sink top and let dry. The gesso will sink into the seams, so you will have to paint the gesso on a few times. After you've got everything filled you can sand it all smooth. Remember you want this sink to look like a piece of cast iron with the smooth finish of porcelain.
When that's done paint the sink top and cabinet. Paint the doors separately. I used Rustoleum white, it's an oil base enamel, gives a good appliance finish. Paint and sand between coats with fine sandpaper, I will use up to 400 grit to get a good smooth finish. When you are satisfied with the surface, do not sand the last coat of paint. Glue on the doors and toe kick. Go to the Kitchen Room Box Stove for a little more explanation of the painting.
I don't make my kitchen cabinets or appliances open. I am not going to open them and I don't leave them hanging open. They aren't hanging open in my full size kitchen. I think leaving them open in a miniature scene emphasizes that it is a miniature. I'm going for as much realism as I can achieve.
For the handles I painted a plastic drinking straw silver, then I tried to slice off identical widths, then I cut these in half. I glued the handles on with super glue, be careful.
Glue your strainer/basket in. I ordered a faucet from Hobby Builders, #938, $6.99.
