This week, a portion of our materials came in which were ordered from McMasterCarr.com. We received, all in one foot, 1/4 inch diameter dimensions, a steel rod, aluminum rod, copper rod, titanium rod and four graduated cylinders. The exact specifications are as listed:
- Low-Carbon Steel Rod
- Multipurpose 6061 Aluminum Rod
- High-Strength 182 Copper Rod
- Ultra-Corrosion-Resistant Titanium (Grade 2)
- 25 mL Plastic Graduated Cylinder, 6-5/8 inch tall (0.5 mL increments)

Since the rods came in each with a 12 inch length, they needed to be cut down to fit the 3 inch requirement. A metal cutting Band Saw was used at the Drexel Machine Shop.

Correct markings were made and the metals were carefully cut in half, then in half again.

After they were cut, a belt-fed sander was used to smooth the rough edges to prevent injury.

The Band Saw cut all the metals with ease, except for the Titanium rod which took at least 10-15 minutes per cut (while other metals took 30-60 seconds).

Nevertheless, the rods were cut to the required length.
