Thanks Baz!

The wife does routinely ask me why I didn't become a Vet(easy, didn't have the $$ for Vet School) or a Marine Biologist since I really dig all things marine related. What is it they say again about hind-sight?[emoji848]

When you "think" you have a grand idea that turns into being a turd of an idea.

Since we tend to walk Henry in the morning hours before work in the dark and want to be visible on our crappy narrow road.

So I had the great idea of visiting a local safety supply store and get one of those reflective vests. What it had gotten me the "two" days I have worn it you ask? Two separate people, one on foot and one in a car stop and tell/ask about the potholes that have gotten really bad since we got 70" of rain.

I'm not sure of to many County/City DOT employees that wear shorts, flip flops walking a 16 lb Schnauzer. Placerville can't boast about have the sharpest "tools" in the shed.

Sometimes you really feel like installing a turbocharger, and then realize one simply won't do:

A company paid good money for engine valves with holes in them? Are you kidding me? No! There was a project to investigate the wear characteristics of camshafts and followers, testing different materials, different coatings and different lubricants. An engine was built with only complete heads mounted on an engine block that had only a crank shaft and the cam-drive chain. An electric motor turned the crank shaft.

In order to run the engine at high speed and have proper pressure on the cam lobes, racing valves were installed in the heads. These sodium-filled racing valves were very expensive and when one broke during a test run, it was a hazardous mess that had to be cleaned up. The solution was to use stock valves, made by the millions that were lightened to racing valve specs. The point was that they did not need to seal a combustion chamber, but only put tension on the valve train. Therefore, drilling holes and facing them off reduced the weight but did not affect their functioning in this application.

The picture above shows two rather “customized” automotive engine valves. They were the first (and only) iteration of the concept. Amazingly, they each hit the target weight within a tenth of a gram! When you work focused and diligently, you sometimes get lucky. Good luck is always welcomed.
