End of Chapter 4. A milestone has been reached.
So, it finally happened. Didn't post earlier because I'm kinda recovering from this semester's finals.
Worked the weekend, Monday and Thursday, because we had, without further prorogue, to present a functional product, that was to be shown on our Industrial Design student expo, were selected projects are displayed for everyone to see. Fancy stuff.
Wednesday morning, at 7:00, hours before the inauguration, we began the final assembly. And the very first test run, all things installed. It went well, everything performed as expected. It's not a perfect product by any means, but what I'm trying to say, is that it worked. In fact, we drove it around the uni, to the place were it was to be shown. Once there, our teacher wanted us to brag a bit (and him, because every teacher takes pride in their student's projects) so every member of the team took a lap around the expo. Heads were turned, specially when every other project in our semester, minus one, were modified bikes and scooters. The other motorized project, great looking btw, had a malfunction a day before, that could not be fixed in time. We won
.
I was not satisfied with our trike's shell, but meh, its not permanent as the pics will show, and I plan to make another one from metal sheet.
All in all, we are very proud of what we managed to make, with no prior knowledge and/or experience, in under 2 and a half months, with mediocre tools and equipment. This might be the most I've learned with a school project.
Have some pics.
"Dimples" made on our shaft so the sprockets/pillow block bearing set screws had a nice gripping point and would not slide.
Pictures.
A teacher snapped a picture of me explaining the thing. That girl is my other teammate.
Here's a
video link of a general overview.
And here's the
one video I have of the second time we tested it, right on the school's workshop patio. Told her not to hit the gas too hard because, as I discovered before her, the painted, smooth concrete floor + dust form everyone's work made for a very slippy surface.
TO DO LIST:
- Rear shocks are too vertical. Have to reposition em, they lock "backwards" with big enough bumps/jumps.
- Chain guard/TC cover
- Kill switch (oopsie, I know its a must)
- Adjust brake pedal, as it is it constantly rubs.
- Seat belt
- New metal sheet body
- Improve wiring
- Hold battery in place with something other that zip ties
- Remove governor
- Fine tune steering
- Adjust TC to max low end torque
- Headlights/brake light/misc. lights
- Miscellaneous things I'll surely come up with
- Miscellaneous things you'll surely come up with
Note: Later that day, we had a terrible time trying to get the engine, the only part of the project we felt proven, to start. Or it would start for a couple seconds, sputter and die. Once we took off the air filter, things were better. I should mention we had like 35 °C (95 °F) that day, and that my city is 1700 meters (a little more that 1 mile) above sea level. I recall reading something on the manual about adjusting stuff due to height.
My conclusion is that the stock air filter is too restrictive and the air was too hot, causing the malfunction. Can anyone shed some light on this? What should I do? Could there be any other explanation? The engine had never been tested in such high temperature, as we build stuff indoors/on shadowed areas. Thanks yall, awaiting comments, tips and everything else you feel throwing my way.
Ouroboros is currently sitting at the workshop patio, will (has to, more like) be moved home by Wednesday, at the latest.
TBC, now in a calm, thought out manner, lovingly and not as a chore.
