A funny thing happened on the way to the bridge ...

Spring has sprung! Saps running. So I had to put my taps out today and get the cooker ready before I could go to Black Hawk High School and check on the progress students Bruce and Alex are making.

What do you see ???

The Sap Sak pictured below is a great piece of engineering. Study the design and you will see how it works. If installed properly the Sak cannot come out of the holder.

Bruce and Alex are setting up a Clamp and Button factory in the Black Hawk High School shop. Earlier I talked about the need for over 100 parallel clamps for assembling the bridge trusses. Plus 28 Buttons will be needed to secure floor joists and roof rafters in place.

They will get plenty of practice setting "stops" and "making fixtures" to locate parts for hole drilling.
Will have to introduce them to some GO  NOGO  gages so they can keep up the quality and meet tolerances of + or  -    1/16".  Even though this is rough sawn material we don't want to get sloppy.

Puzzler - How many gallons of sap to make one gallon of Maple syrup?
