Children live in their world. And for this reason, they need to have the appropriate furniture. We propose a quick guide for making a stool for children. We believe this project could be easily achieved. Moreover, the result can be painted and customized as desired, in various colors.
Tip: To make it more fun - involve your children!
The following installation instructions are for medium-density fibreboards (MDF) with a thickness of 19 mm. If you use other materials or thicknesses, you will have to adapt accordingly the product list. You may also consider requesting for cutting tasks (of the boards needed) at your building supplies store or from a professional carpenter.
The stool itself is made, for reasons of stability, by two overlapping parts: a table-shaped base of a support plate and some screw clamp bars, and construction is provided with quoin type legs and headboard seating. Front has only an aesthetic role; its shape is your choice.
Possibly a spray gun
Fine Spray System
Set bits for wood
Sandpaper, grit 120-240
Tape measure, soft pencil, eraser, sharpener
Putty or wood putty
Medium-density fibreboard ( MDF board ), 19 mm.
Step 1: bolted quoin legs.
Prepare the holes in flat plates for the assembly of the chair legs, by screwing with the narrow, and drill with 4-mm wood drill bit. Dip the holes on the outside dimensions of the screw head; later cover the screw heads with filler material so you no longer see them (during the surface treatment phase). Merge by screw, in quoin shaped, a wide board and a narrow one for seat’s feet, with 3.5 x 40 mm countersunk screws.
Tip for screwing together two pieces of wood:
Always execute in the piece that is going to be screwed first a preparation hole with 0.5 to 1 mm larger than the diameter of the screw; the hole has to be enlarged for the screw head. In the second piece, always run a preparatory hole of 1 mm smaller than the screw diameter.
Step 2: Drilling prior to connecting rod.
The four bar links are screwed from back into the corner legs. For this purpose, preliminary drill both sides of the joint bars with a wood drill of 5 mm. Be sure to alternate holes in cross, but never drill at the same height, so that the screws do not hit each other in the common bar.
Step 3: Merge the lower plate and connecting rods.
Place the support plate on the saw horse and align joint bars over corner. Mark with a pencil the inner parts of the joint bars to the support plate; now mark the square areas on which connecting rods are placed under the base plate. Determine their centers by drawing diagonal lines from their corners.
Perform preparatory drill holes using 4-mm wood drill through the marked centers, in the base plate and deepen the holes, so that later the head screws remain protruding above the surface. Now align the joint bars again in corners and screw them through the support plate 3.5 x 40 mm with countersunk screws.
Step 4: Merging quoin type legs with base.
Place the base, consisting of base plate and joint bars, on the working surface so that the bars are facing up. Now place one quoin type foot made in Step 1 on the bars. Screw the quoin type leg through preparatory holes with the joint bars, using machine screwdriver and flat head screws of 4 x 50 mm. For the two screws on the inside of the joint bars you have to detach again the table legs of the support plate, because the space between them is too narrow and does not allow handling easily the machine screwdriver.
Step 5: screwing the seat plate.
Perform with the drilling machine and 4-mm wood drill, four holes in the base plate and deepen them on the bottom. Place plate sitting on a flat surface and align subassembly feet at the corners with it. Then screw the plate with the legs subassembly using the machine screwdriver and the 3.5 x 40 mm flat head screws. The stool itself is now ready.
Step 6: Cut the outline on the front plate.
The special charm of this piece of furniture is conferred by the front plate, mounted on a narrow side of the stool. Fit the front plate with transferred contour with two vices on the work surface. Use the usual holds to avoid the appearance of pressure tare on the work piece. Now cut out the outline using the router.
Step 7: Merging contour plate / faceplate with stool.
Drill two holes in the narrow side of the chair legs. Secure the plate in vices, at the desired height. Finally, screw the plate on the back, through the legs of the chair, using the machine screwdriver and the 4 x 90 mm flat head screws.
Step 8: Surface Processing.
To obtain a higher quality surface before assembling furniture body, you should devote for its preparation. First, fill with wood putty scraper and putty the screws holes (if any) of exposed surfaces of MDF boards. After drying (follow manufacturer's specifications) smooth respective places with 120 grit sandpaper.
Then faceted edges of all pieces of MDF by working them with 180 grit sandpaper in a 45° angle so as to create a small bevel. Machine MDF with sander and 180 grit sandpaper.
Step 9: Surface treatment.
First, carefully read the guidelines for processing and manufacturer safety and labor protection. Work in a well-ventilated room and avoid smoke, eating or drinking while working. Apply the priming filler with the roller or possibly a paint spraying system. Let it dry thoroughly. If you want to use in the next stage another product with your fine spray system, you must change the paint tank.
Tips for MDF: MDF has highly absorbent surfaces. In this regard, you should pay attention - meaning to apply several layers - especially on the edges. You can avoid difficult grouting filler (so called isolation absorbent surfaces) using MDF primer foil. This provides perfect coverage without fillers - at least on the surface.
Sand smooth the edges surfaces; magnify this purpose grit sanding paper from 180 to 220 and to 240.
Step 10: Varnishing visible surfaces.
Varnishes are available in many variations and price categories. Factors in choosing varnish should be its workability, your technical equipment and requirements related to the quality and durability of machined surface. Seek advice from your authorized dealer. And if you do not have much experience in varnishing, it is advisable to practice on sample piece.
The most beautiful results are obtained with acrylic varnish. They can be diluted with water and are available in many different colors in any DIY store. These varnishes are applied very easily and quickly with a fine spray.
Spoon varnish in the paint tank and dilute it with water if necessary. Adjust the spray jet at the nozzle and the varnish thumbwheel using a sample plate. Spray jet can be set vertical and horizontal on surfaces and conical jet on edges. Varnished best interior edges first, then the outer and eventually the surfaces; the latter ones, in even, parallel passes.
What is inevitable when spraying in different colors two neighboring surfaces: must work with glued profiled templates to delineate cleanly the painted surfaces in different colors.
