Mini-Fix fixtures are a good way to build your own knock down furniture with pre-laminated plywood/MDF. Pre-laminated boards, cuts down the build time drastically. Whatever you make, is easy to knock down and you can reuse the material for a different project very easily. On the other hand, the fixtures are not very robust and can break during repeated assembly/disassembly. They can carry a limited of load and will need some additional design considerations for heavy load. The fixtures are not expensive, @ Rs 7 per set, buy additional sets when you get the hardware to replace the broken ones. There are some wood vendors who will paste your choice of laminate on to your choice of board (ply/block board) and make pre-laminated boards to your requirement. Alternatively, you can buy the laminates and plywood separately and laminate the boards yourself, prior to starting the main work. I got pre-laminated plywood @ about 95 psft from a local vendor. The first day started with cutting the side panels and making a jig for drilling the holes for mini-fix cam and dowels. Next, I drilled all the holes on the side walls and inserted the nylon inserts to hold the pins in place. The jig, which was made earlier, was used to guide the drill and make holes. I was making a cabinet to hold Bosch Ovens. Bosch microwave weighs about 16 kg and the oven weighs 35 kg. For carrying this load with the mini-fix setup, I made dados in the side wall panels where the ovens were to be placed. Mini-fix dowels were also placed in the dado groove. Dados would carry the main load and the mini-fixes would hold the structure in place. These shelves were wider than the other shelves to account for the dado depth. Dados were routed with a Trim/Palm Router, using the jig as guide. Holes for the cam were made on shelves with the same jig. 3 sets of mini-fixes were used for each shelf joint. After all the holes were done and the mini-fix dowels attached, each panel and mini-fix was tested individually ("unit testing") to get a good fit. Same process was repeated for the other side. The complete assembly was put together for an "integration testing".
10 mm plywood was screwed on the back side. The back panel prevented the structure from swaying sideways and provided rigidity. It took about 10 hrs of work to get to this point.
On second day, all the exposed edges were covered with white PVC edges for edge binding. Fevicol PVCFix adhesive, which came in a handy dispenser tube, was used to bind the PVC strip on the edges. Overhanging PVC Strips were removed with a sharp chisel.
Panels for the doors and drawers were also edge-bound. Hettich fittings were used for doors and drawers. Teak beading was pasted on the edges resting on the floor. Footboard installation is still to be done. Material:
