v belt, you mean an automotive 'fan belt'? That's something that would cause serious damage...

For an easy flogger, you can get a pair of motorcycle leather lever covers or handlebar covers. You know... tassels. The handles can be wrapped around and tied onto a dowel. The 'falls' are exactly like you would make for a flogger and it's all ready to go, relatively inexpensive at $15 for lever covers to about $35 for handlebar covers, and you get two each, so can even practive double-handing.

As for learning rhythms, a pillow gives the right recoil... and your leg will tell you what's too hard.

The other ideas, especially what is referred to as "pervertables" (meaning everyday items you can suborn for bdsm use) are excellent, as are items commonly found in tack stores and ranch&supply stores.
