It's March, and Project REV's construction is just about right on time!
Before the break, our students are working to add the next major component to the build.... BRAKES!
We were able to attain two disc brake calipers from our community partner Spokes N Slopes, and with them, the REV team was able to cut and design new mounting brackets to get the calipers on the spindles.
First, we measured the distance between the calipers and the spindles, then designed and 3D printed a prototype bracket to see if the hardware would hold in the appropriate place.
After relocating the front wheels and spindles to a portable cart, students were able to more easily install the custom brackets and weld them into place, readying them for the caliper assemblies.
While the students test fit the calipers to their new brackets, other members of the REV team worked on installing a set of bronze bushings in the front axle, to tighten up the play in the front wheels. We noticed that the front wheels do camber in a little under weight, so the bushings will help the minimize the camber and make the ride more stable.
Once the brake calipers were on, the grade 10 students tested the brake force operation and found it to be reasonable when unloaded. The real test will be when the two front brakes are installed and a brake lever attached to operate them. For now, the front wheels were reattached to the car, and brake cables installed in a temporary jig, to try its operation...
And since our team is eager, we had two grade 10s install the electric motor on the rear axle on a large wooden mount so when we return from March Break, we can test and examine the propulsion system and work out any kinks that are sure to creep up.
And with our cool machine taking even more form and putting smiles on our faces, the REV Team wishes everyone a safe and happy March Break!
Tune in soon, to see post number 10, and check out our next stages of the build!
