Cruising to airshow, severe vibration occurred. Cut power, glided to dry lake, uneventful landing. No damage to aircraft or pilot. Subsequent inspection revealed internal propeller failure. Called mayday on 121.5. Got immediate response from someone official. Can't recall who for sure, but think it was las vegas approach. Search and rescue arrived about 1 1/2 hours later -- pretty good I thought. I had water with me, and it is a good thing. Even 1 1/2 hours without water, especially had I been hurt, would have been very uncomfortable -- temperature was already 100 degree fahrenheit. Callback conversation with reporter revealed the following information: callback was made to determine what area the forced landing was made -- near the california border south of las vegas near highway 15. During the conversation I learned he was flying a zlin to an airshow at salt lake city. The propeller was a controllable pitch and the spider was defective. He learned from the experience that distances on the desert are deceptively farther than they appear. What looked like less than a mi was about 6 mi.
