Kevin is bring a rigging training aid today. Looks like the vinyl flooring might get moved too.
Update your blogs, lots of details, pic and links. Your practical grade is largely based on your documentation. The job is not over until the paper work is done.

Training aid is a  Spanco 1 ton Portable Steel Gantry Crane with attachments.

Cast and copper assemblies for DWV. Soldering large dimension copper with 95/5 solder.

 Why would you use copper DWV?

 "The smaller diameter of DWV tube and fittings makes it possible to install copper drainage systems where other competing piping materials would be impossible, difficult or more costly. For example, a 3-inch copper stack has only a 3-3/8-inch outside diameter at the fitting and can be installed in a 3-1/2 inch cavity wall." Copper Development Association

Why do we ream copper pipe ( or any pipe for that matter)?

Erosion corrosion.

Tube Bending added to the mix. See page for projects. Complete math assignments.

Pipefitters need to bend all sizes of pipes and tubes from the smallest sizes used for medical gas or instrumentation, through 1/2" 3/4" and 1" steam tracing lines to heavy duty pipeline pipe bending up to 60" in diameter.

Ridgid makes tools for  hand tube bending copper or stainless steel. Tools for making bends in larger pipes, especially steel pipes for steam tracing are done with electric or hydraulic motors.


Check out this bending tool.



Here is an example of tube bending for steam tracing. The tubing is laid over the pipe, under the insulation to keep systems from freezing up.
