The Oft’ Misunderstood Impulse Coupling

The Oft’ Misunderstood Impulse Coupling

When I speak at various events, one of my favorite show and tell items is a magneto with an impulse coupling attached. It’s a great visual aid which allows for a very useful demonstration of an ignition system during engine start. More importantly, it demonstrates why...
Borescope Revelation: An Oshkosh Brainstorm

Borescope Revelation: An Oshkosh Brainstorm

I get to attend almost the entire week at Oshkosh, known these days as Airventure. Some friends and I share a house for the week and use it to enjoy some respite from the somewhat intense activities on the Airventure grounds during the day. I walk six or more miles...

Exhaust Valve Save (or Precancerous Treatment Success)

Early detection I happen to be very light complected, complete with freckles and sandy reddish hair, so excessive use of sunscreen is just a normal part of life. They say “you can’t swim outside your gene pool” which, for me, means that I get to make visits to the...

I can’t give a count of how many batteries I’ve installed over the last four or five decades, but it’s a bunch. Each new battery arrives with instructions for initial servicing, which I read way back in the day and assumed that the batteries hadn’t changed, so the...

Economy of Effort

I cringe every time I hear the phrase “there’s more than one way to skin a cat”. First, who would do such a thing and why would they ever do it? The underlying truth remains that there are usually multiple methods to accomplish a task. The Vedic Science principle of...

You Did What to My Airplane!?!?!

One of my goals in life is to limit surprises.  Not those surprise birthday parties but rather those other unwelcome surprises none of us enjoy.  Just a few examples to get your imagination going: credit card statement with unknown charges, unwanted legless critter...

Annual Crusade (My apologies upfront if I sound too preachy)

I decided some years ago that I just didn’t want to crawl under my cars and do the oil changes. It’s dirty, messy and just a lot of trouble. I have my favorite car mechanic that I trust for all things automotive. He always has some sort of special offer which usually...
