Bicycling to Air Force Museum
Saturday, June 11th, 2016 | Author:

I went on a 25-mile bike-ride with my buddy, Marc, to check out the new additions to the National Museum of the Air Force.  It was beautiful weather and a great day for a ride.  We even rode by the Riverscape fountains in downtown Dayton, which cast a slight rainbow (see second photo below).

Installing New Basketball Hoop

Update

Phase 3 is now complete.  My buddy, Redman, showed up to help me mount the backboard, rim and net.  I also planted sod around the concrete base.   The combination of the solid pole filled with concrete and rebar, along with the glass backboard makes for very nice play.

Phase 2 of three phases of the solo installation was completed this weekend (Phase 3 is the installation of the glass backboard planned for next weekend).   The large Spalding box was delivered on Friday (see first photo below), but the real work started at 7:00am on Saturday with a visit to Menards to buy the necessary building materials and to rent the delivery truck.  It was a workout just picking up the nearly 1,000 pounds of concrete and loading them into the bed of the truck (see second photo below).

I enlarged the original hole to a full cube 2′ x 2′ x 2′ and I built a wooden form around the top of the hole (see third photo).  I then constructed a tripod out of 2″x4″ wooden studs to ensure that the pole maintained level during the concrete pour (see fourth photo).  After installing additional rebar in the base and center of the pole, I started mixing the first of 10 bags of Quickcrete (no crack recipe with chopped fiber).  After 3 hours of mixing, pouring, and tamping concrete (including pouring concrete down the center of the pole using a make-shift funnel), I ended up with what you can see in the sixth photo below.

The basketball hoop & pole for our home court that I installed 22 years ago finally gave way (the 3″ diameter metal pole rusted-through).  I’ve ordered a new in-ground pole and backboard, which requires that the previous concrete base be removed.  As you can see from the first photo below, the metal pole snapped right at the base, and the grass has grown over most of the concrete.

Naturally, the first step, as shown in the second photo below, was to remove all of the soil around the concrete base.  While it was challenging, I used a couple of 4′ long crowbars to help pry the 400 pounds of concrete out of the hole (see the third photo).   The fun part was using some engineering skills to determine a reasonable way of getting the huge block of concrete into the wheelbarrow.  As you can see from the fourth photo, I leveraged the technique that the Egyptians and Israelites used in building the pyramids — a slight incline plane.  After all was said and done, I ended up with a hole just about ready for the new 4″ square pole.  (Note: I did all of this work solo).

Chair Repair – Is This Engineering?
Friday, April 22nd, 2016 | Author:

One of our kitchen chairs had all four screws holding the back onto the base snap in half.  I played upholstery expert and carpenter (spent most of the time removing staples) and performed a repair….  Missy says it’s as good as new.

Digital Work Instructions
Thursday, April 07th, 2016 | Author:

There is an interesting white paper about smart manufacturing and digital work instructions at the DISCUS Software Company web site.   This paper provides 7 insights into what’s necessary to bring electronic work instructions to the marketplace. It provides a nice backgrounder on the history of paperless manufacturing.  It also describes the steps necessary to easily incorporate mobile devices into modern manufacturing.

With the drastic reduction in the cost of sensors and networking devices, there is an emerging opportunity for collecting more data from the shop floor.  I would expect many more companies to start considering the use of tablets and lightweight laptops out in the factory.

Life and Science are Uncertain Endeavors

All I can say is “Well, Duh!?”   Where have you been?  Voting for someone such as Obama?

Contradictory advice from two European-based agencies about the cancer risk posed by the weed-killer glyphosate offers clarity on only one message: that uncertainty is inherent in the scientific process.

Flying Over Home

As you can see from the photo below, my flight last week from the Dayton Airport took off right over Butler Township. If you examine the photo, you can see Samaritan North, Meijers and the Englewood Dam.

Visit to Wegerzyn Metropark

Missy and I recently took a nice stroll through Wegerzyn Metropark located in North Dayton (see photos below).  It’s a fantastic botanical garden with a mix of English style formality along with traditional midwestern plants.
