This Instructable will show you how to design and build your own Ripstik that "sticks" out in a crowd. Since it looks like a fish, I call it the FISHSTICK.
The torsion bar is hidden underneath the board and is basically made of a door hinge combined with a very stiff blade of a saw. It took me quite some time to get the "stiffness" of the board right, but with this set-up, the feel of the board comes very close to that of an original Ripstik.
Wolfshade has posted an I'ble on how to build a Ripstik back in 2009. Check it out here because I learned some aspects of it.
The motivation for this project came from the fact that all Ripstiks look alike. Secondly, the design of them simply resembles of two canoe paddles connected by a rod. Can't this be improved?
Step 1: What do you need?
- A plywood sheet to make the deck (90 cm x 35 cm x 0,9 cm)
- A pair of casters and a pair of wheels (diameter 7,5 cm).
- 2 Wooden blocks to connect the wheels (the base of the caster is 6x6 cm, hence the block must accomodate this size).
- A door hinge: width 8 cm (open), length 9 cm.
- A bolt (length 100 mm, M10) with a nut. This will replace the pin in the hinge.
- 8 screws for the hinge (shorter than the thickness of the deck, in my case 9 mm)
- 8 screws for the casters: a set of long ones (25mm) and a set of short ones (15 mm).
- 1 bolt, a washer and Tee Nut. (all based on M6).
- A blade of a saw, 14" x 1 3/4" X 0.062, and cut it to a length of 25 cm. I used one of BLU-MOL (works excellent). You don't have to use a saw, just as long it is a strong and elastic piece of metal. Some putty knifes are excellent alternatives.
- 8 Dowel pins (6 mm diameter).
- Masking tape and paint.
