I wanted to make a gift for a friends daughter for Christmas. My wife had already purchased a small doll for the girl, a cot would accompany the doll perfectly.
Step 1: Step 1 : Design the Cot
the cot was designed in solidworks. The cot was deigned around the dimensions of the doll.
A pocket will placed in the base and head board so make assembly easier and to avoid visible glue lines.
The sides and base will be cut using a mitre saw so the DXF for these parts were not exported.
once the design was complete, a front view DXF was exported to be used to program the CNCs path.
Step 2: Step 2 : Create the CNC Programs
The DXF files were loaded into the CAM software to program the CNC paths.
a Pocket program was used for the alignment pocket and a profile path was used for the exterior.
the child's name was added in the CAM software and a pocket program was used with a depth of 1mm.
*note* the name in the preview image is inverted as one of the axes on my CNC is inverted. The backwards name came out the the correct orientation on the router.
Step 3: Step 3 : Cut Out the Parts
The parts were cut on a desktop CNC router using a 4mm single flute cutting bit for both the pocking milling and profile milling.
Blue painters tape was used on the surface of the ply wood to prevent wood splintering.
If a CNC is not accessible, the parts could be cut out using a jig saw, scroll saw, coping saw or anything that can cut curves. The templates are attached below.
Step 4: Step 4 : Assemble the Cot
Once all the parts have been cut out, a light sanding was appied to the edges to break the sharp edge. The edges of the side pieces were rounded over further to create a 4mm radius.
Glue was applied inside the pockets and the parts were assembled.
Weight was applied to the top of the cot while the glue was setting.
After the glue was dry, a coat of tongue oil (food and child safe)
Step 5: Step 5 : Try It Out
Fully assembled and oiled. the dolls fit and it rocks.
Step 6: The Files
attached are the files if you would like to make your own.
