Happy Thanksgiving!

We're in the home stretch for 2017...  Another Thanksgiving is upon us, I hope the folks that wander by my blog are well and for those celebrating the holiday - my kind regards.

Let us not forget why the day came about.  A prayerful reflection of thanks for the bounty of harvest.  No matter what your tradition, most all of us have paused to give thanks for something. 

Just a head's up to the torsional vibes visitors... I've been meaning for a long time to post my notes and calculations on damped forced response of torsional systems - I've been porting my old fortran and building a gui for some of my own engine design tools, so expect a post on the basic algorithm in the months ahead.   Maybe some journal orbit analysis too... My code uses the mobility methods of Booker, so - not so accurate anymore as journal tilting and the ensuing mixed mode lubrication regime is now pretty much the standard approach...

Studebaker Update Coming Soon...

Winter is slowly creeping in and with the busy schedule I've been keeping there's not been a lot of time to post. 

The winter  ice will soon cover the entire lake...

So what about that Studebaker?  Pics to follow!  I'm starting the rebuild of the motor.  This old L-head is pretty simple but there are a few pretty cool design features the engineers at Studebaker evolved during the production run of this engine.  If anybody needs dimensional info on the 3M series blocks - I'd be happy to oblige by measuring my '47. 

I'll post as I go through the re-build, my the goal is to have a running motor by April. Then I'll tackle the transmission and rear differential.

I rarely voice an opinion on such things...

But this  juxtaposition was too fantastic to ignore!

Antarctica’s ice may melt faster than previously thought as result of a newly discovered network of lakes and streams that destabilize the continent’s ice shelves, according to new research — making them more vulnerable to collapse.
Scientists have long understood that water from melted ice harm ice sheets by flowing into cracks and refreezing, but that phenomenon was thought to be limited to a small part of the continent. Researchers behind a new study published in the journal Nature this week found that the process has been ongoing for decades and actually occurs across the continent including in places where scientists did not think liquid water was commonly found. The pace of the damage will increase as temperatures continue to rise as a result of man-made global warming.

Study bolsters theory of heat source under Antarctica

A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet. Although the heat source isn't a new or increasing threat to the West Antarctic ice sheet, it may help explain why the ice sheet collapsed rapidly in an earlier era of rapid climate change, and why it is so unstable today.

Remember Lord Kelvin's famous quote about the aeroplane?  He also claimed radio had no future and X-rays were "clearly" a hoax...

The beauty of winter has just begun!

I love the change of seasons.  This early snow will not last, but it is beautiful...

Winter is slowly making it's entrance
AML NLO, JRO and SEO AML always!
