Step 10
Skip this step and continue adding feet if you want to go that way.
Okay, take the last piece and trace it onto some more 12mm MDF; I had some left over since I had to get too much in the first place. We are going to modify it, however, by adding tabs to screw through the holes as shown below.
To know where to put the tabs you will just need to mark them really roughly while you have it in the boot. After the first cut just take it back to the boot and cut more off if need be until it fits.
Step 11
Skip this step if you decided you don't want the spare wheel.
Take the wheel cover out and cut or drill a circle in it that is big enough to get a finger in; this will help you lift it out and get it back in easier.
I also attached a scrap bit of MDF that will rest on the tyre, making it more resistant to sagging and overall more solid. You will need to be the judge on thickness here, just trial pieces underneath till it is level.
Step 12
It is now time to screw it all down if you are happy with how level it is. Follow this process for each section. Take some single sided tape and cut a bit off. Place it upside down on the feet. Then carefully put the piece of floor on the feet where it will be attached; try to lower it all at once in the correct position, you can always redo it if need be. When you take it out you will have marked where you need to drill.
Drill through the centre of the tape, take the tape off and put it back in the boot. This method is actually very easy and very accurate. Put the floor piece back in position and re-drill the holes again; we do this so the feet also have matching holes. Now grab your screws and secure it tight. Then move on to the next piece.
Note: The cow is a mini vacuum that I used to remove the dust and stuff caused by drilling holes.
Step 13
The last step is to remove the masking tape from your carpet, clean it if needed and put it back in the boot. Now, you're done!
