One method of removing a hex screw when the head has been stripped out. NOTE: While the original problem remains unchanged, I now find the HEX screw was the STAR type and using an Allen wrench in the beginning only made the problem worse, duh!

‘Pañc hazar chakra kai andar’ or ‘Within Five Thousand Cycles’ is a piece for Yamaha Disklavier that attempts to explore the instrument within the context of John Cage inspired piano preparations (utilizing machine screws, flat mudguard and standard washers, plastic and brass olives, paper clips, cup head bolts, hex full nuts, white board and fold back clips), North Indian ‘Hindustani’ derived cyclic rhythmic patterns (juxtaposing two contrasting talas: Jhumra, 14/4 or 3 + 4 + 3 + 4 and Champak sawari, 11/4 or 4 + 4 + 1½ + 1½), analogue synthesis (including Arp 2600 LFO/Sine Wave filter sweeps, envelope filtering and Mu-tron Bi-Phasing), digital effects processing (ring modulation, distortion, 4-band eq, chorus, reverb, delay), studio generated harmonic resonance or ‘sympathetic vibrations’ and modern digital hard-disk recording technology. In 2005, the work was arranged for Three Percussionists, Prepared Pianoforte and Tape at the Request of Australian Ensemble Speak Percussion.
