So I noticed a problem this past weekend with t' Aerotech Universal Delay Drillin' Tool that a customer showed t' me at a rocket launch. T' one he had wasn't cuttin' into t' delay grain o' his rocket motor. What happened was that t' drill was set at t' wrong depth. Fortunately, this is a very easy fix, and it doesn't require returnin' t' item back t' t' manufacturer. There is just one little screw holdin' it in, and in just a few seconds, me bucko, it will be adjusted and cuttin' t' delay times you need for your flight. And after you make t' adjustment, it will be much more accurate in settin' t' delay time o' t' motor. You'll also see how it works too, just in case you've never used a delay cuttin' too before.
