Back at It

Now that school is back in full swing, the TCS Kids' Cafe is back working on the XS650.  Over the course of the summer while the bike was hanging out in Mr. Sheppard's garage, a few templates were made in order to accommodate the frame modifications, as well as mount the rear taillight and turn signals.  Starting with cardboard first, the goal of this session was to create the finished pieces out of aluminum.

Using the cardboard piece as a guide, we began measuring cut, fold, and drill marks in the aluminum.

During the course of this process, we used some of our mental math skills, and discussed the relative ease of working with the metric system.  "Half of 40mm", is far easier to calculate in our head compared to "half of 1 and 5/8 inches"!

 Starting with pilot holes, the students drilled out the various mounting points for the tail light brackets, frame mounts, and turn signals.

We also discussed how it is far easier to mark, punch, and drill holes (pilot holes or finished holes) on a piece you are working on prior to final finishing or bending.

The aluminum sheet we used for the battery and fuse box mount was a bit thicker than the taillight bracket -- like most shears, the material is cut by stepping down on a foot bar to operate the cutting edge.  The students needed a bit of "help" from Mr. Sheppard... both girls were too light to cut the material!

The tail light bracket on left, with the cardboard template on the right.  The larger "keyhole" needs to be finished later; the wiring for the tail light passes through the material at that point.

One hour's work:  the tail light bracket is 90% complete, and the battery bracket has been roughly cut out.  Final finishing will be done once it is test- mounted to the frame.  Note the cardboard template... irrefutable proof that Mr. Sheppard (occasionally) eats Froot Loops.
