Step 1: Things you need from the hardware-shop
(one should fit in the other one)
- 4 pipe clamps with nuts and props
- 5 webs for handsaw
- 50x40cm pice of 12mm plywood
- 2 rotating furniture wheels
- anti-sliding tape
Step 2: Making footpads
One sould be 30x20cm and the second one 40x20cm.
You can make any shape you want.
Drill 4 holes for the clamps in each.
Later you will drill 4 holes for wheels but not until you make wedge-support for wheels.

Step 3: Making torsion-bar
Cut the thicker one in half.
Take the halfs and screw them to the board using the clamps
Step 4: Making torsion-bar spring
Take two pices of 5mm thick aluminium 10x30mm.
Drill 3 holes in each. Two 3mm and the middle one 2,5mm and make a thread for 3mm screw in it.
Screw those plates the the board just behind torsion bar
Put all of the torsion-bar parts together.
Put the handsaw blades inside the torsion-bar.
Mark where the holes for screws should be and drill them in the blade-halfs
Step 5: Wheels
They should be about 30 degrees. You can make it a bit more or less it wil change the way the board feels.
Place the wadges on the board and mark the places where you need to drill holes. Drill them. The wedges should point the same way.
Screw rotor wheels to the board.
Replace wheels with rollerblade wheels.
