I stumbled across your mag via a friend who was putting together a speed controller - and I remember you from SC and your recycle articles. What a bloody good read is this effort! - heaps of interesting stuff, I am a electronics tech and a metalworker, no real interest in cars, but you write well enough to make them interesting! Sorta like when someone gives you a big stack of old EA, AR magazines, and you can look forward to hours of reading.
Loved the setting up a workshop series (I can dream), your experiences as a car detailer, and the "how to sharpen drill bits" - the last one is about the best description of the whole process, clear, concise, and lucid without excessive jargon - it took me several weeks at TAFE to learn drill sharpening, wish I had your article at hand then. Still at TAFE, doing Fitting and Machining, so can only concur with your comments about machine tools and the knowledge required to use them - I will never be a skilled tradesman, not getting enough machine time, but its been worthwhile.....Andrew Blight
RPM vs Time
First I'd like to start off by saying that I am a long time reader, and I thouroughly enjoy your publication. On your Ultimate DIY Automotive Modification Tool-Kit, Part 4. You failed to mention an RPM v.s. Time graph that can easily be made using a stopwatch and MS Excel. This is a method that I have used for years to measure gains in performance before and after a modification is made.
I enjoyed reading the DIY part 4, but I feel that RPM v.s. Time is an essential benchmarking tool as well.Christian J. Moya
We don’t see any advantage in measuring rpm versus time rather than road speed versus time, and in the case of auto trans cars, there are distinct disadvantages in taking that approach.
