Demonstration o' usin' 'explosive bolts' for t' separation o' solid rocket boosters (SRB) by Richard Dierkin' on high power rockets at t' December 2010 monthly meetin' o' t' Rocketry Organization o' California on Lucerne Valley Dry Lake, Mojave Desert, California. It worked perfectly with all four boosters ignitin' as planned and also fallin' away together. Ahoy! Bolts made from nylon screws drilled out and e-matches put in each. Excellent job Richard.
