Project Terminology

·        A brace is placed diagonally to prevent networks of beams from collapsing.

·        A brace has 1" chamfers that blunt 4 corners that might have protruded.

·        Interior parts have 1 3/8 inch diameter 'thru' holes.

·        Exterior parts have 1/2 inch thru holes with 1 3/8 inch diameter by 1/2 inch deep counter bores on both sides.

·        A Spacer has one hole and is 3 1/2 inches long

Project Sponsors

The projects enjoy the generous support of the public schools. School staff members accompany the students and assist with the projects. The schools pay for project preparation, instruction and coordination (mostly from Vermont Tech faculty and staff), and materials like glue and ice cream.

The projects also enjoy the generous support of Vermont Technical College. The college contributes facilities (like computer labs and machine shops), technician time, and oversight and assistance (payroll and invoicing) from the Academic Dean’s office.

Further, this year we thank Bernie Allen of Allen Lumber for donating some 2x4’s and John ‘Dive King’ Gleason of E. F. Wall & Associates for saving some good scrap from the dumpsters.

 

Warning to Parents and Students

In these projects many of the technologies are inherently dangerous. Of course, if a student is not comfortable with a dangerous technology, someone else will use it for them.

Students and parents should also understand that a place, where technologies like power tools are used, is an inherently dangerous environment. We have been very fortunate in recent years to have avoided a terrible accident.

If a student shows a dangerous lack of skill or judgment, an instructor or staff member may remove them from the project. Many risks, however, can not be countered by close supervision. All students and parents should be warned that errors in concentration, skill or judgment can quickly lead to injury.

Also, even a person doing the right thing might get hurt by a freak accident or someone else’s mistake.

We recommend an attitude of calm mindful respect for the inherent dangers of technology.
