The soloboss guide is down so I'll try my best to tell you.
1. use/get two cups/cans or anything with the same height.
2. snap your set of blades together, some say with screws, but I don't.
3. place the ball ends of the blades on the edge of each can/cup.
4. use tape on the end of the lighter blade to counter balance it.

Hope that makes sence.
If not search on youtube. I remember someone made a video of this.
