A Marvel of Mechanchis

Wednesday, August 21, 2013

            For the first time, an in-campus Industrial Training was being held in the history of our Varsity. There were blended flavours in the ambiance; those who actually wanted a conditioning were cheerful while those who used to get a prefabricated training certificate by their father’s grace were badly disheartened and were lashing out. But there was nothing we could do. Administration’s decision was final.

In the initial phase of training, we were being taught Pro/E and I was very fortunate to have already done the certified course and as a result, I was able to build a good impression over Deepak Sir (Founder of Technology Uncorked) that helped my team in earning a good sum of kudos. Sorry, I escaped informing you that I was chosen as the team leader of one of the 15 teams (4 members each) who had to design and manufacture a mini car that would actually work.

So, after 3 weeks of practicing the design software, it was finally time to start working for the car. We as Mechanchis (mechanical students) had to design the main structure of the car. Everyone in the lab was delirious about it, unaware of what’s gonna happen in the near future.

Next day, we all arrived at the Machine Lab where the accessories were dispensed. The accessories included a 1 sq. ft. metal sheet, 5 gears, 2 motors, 4 wheels, shafts, collars, a spanner, plier and varying types and sizes of nuts, bolts and washers. After distributing it all, the incharge said, “Commence with your innovation Boys.”

We quickly snaffled our stuff seated in an orbitual scaffold around it. Suddenly, we realise, “How could we?” I mean, it was the first time we had such a rattling project in our hands and hence, were clueless of from-where-to start-it.

An hour passed, and everyone still grabbing something or the other in his hands, dumbed down to lacking intellectual acuity. I and Puneet have done diploma in Mechanical so we had some knowledge of a differential (differential is a gear mechanism used to vary the speed of both the rear wheels that helps in easy turning without skidding), but this was totally dissimilar to a real one. We just had a set of gears to convert it to differential. So we went to the Automobile Lab to recall the real differential. The actual differential has 4 planet gears but we were provided with only 3. We just started hashing out our approximates and by the end of the day, we had our differential in our hands. The sense of achieving a step towards accomplishment, I cannot convey the blitheness of that very moment.

Our Differential

The succeeding day, was a much fresher one. A chill of drizzle showers made it more of an enjoyment-day. People were quite contented with their previous day performance which made them more cavalier. One of my team-mates went to the Administration Block to help his friend with his official work, another: busy having talks with his girlfriend. I, along with the remaining fellow, started discussing about the main design of the chassis (Chassis is the base plate of the car on which the entire parts of the car are attached). He was more of an amusing kind of guy. So, as expected, he started giving comical suggestions. Rather than taking heed to his silly talks, I preferred spectating others’ seeds and assisting my roommate’s team in their toughie.
Time went on, and by the end of the day, we had nothing, but the same differential, we had the previous day (though, that too got loose). I was really frustrated with our slothfulness and negligence. Getting back to my room, I took a notebook and started working on the chassis conception.

New day, surfaced with new hopes. It was raining really hard that morning and it was time to pull up our socks. I called up all the team members to be present in the Lab no matter what emergencies they have. We continued our job and the best part was that the main chassis designed by me was accepted by all others without any confusion or hesitation. And to our greatest surprise, ours’ was chosen the most unique design due to its slant shape (thanks to our team leader :p). Puneet and Pratul started snipping off the sheet as per the design and Himanshu escorted me to the Fitting Lab where we had to get down to the front steering wheel mechanism so we could turn the vehicle as and when required.

The Fitting Lab resembled more of a fish market. There were howling mouths, thrashing hammers, assailable hacksaws, and incredible brains, rolling grinding wheels, screwdrivers, spanners, acutely tapered chisels and innumerable class bunks. This time, we had to construct a rack and pinion steering mechanism out of a plastic cube and a plastic square rod with teeth at two of its polar faces. The day was done and we weren’t yet done with the chassis or the steering work.

The following day, there was a lot of mishmash. Time was running short and we had a lot of work yet to be accomplished. It took us an about hour to cope with the left over work, and now, all we were left with was the assembly of these parts. We had to take care of the placement of front as well rear wheel mechanisms, 2 motors, not forgetting the constraints of the chassis itself. It was the most elusive of all days and everyone was working selflessly and nothing need be assigned to them. And to its conclusion, our miniature vehicle was geared up by the final tic of the clock, along with a good news that we’d be meeting the remaining members of our team (3 guys and 3 gals from electronics) within the next 24 hours.

The Electronics associates had to generate circuits to control the vehicle with a remote control and the indicator mechanism. We took our designed car to them to look up for the placement of their various parts and to check their functionality. Due to restricted space, a roof had to be superposed over the car as an arrangement of electronic circuits. In this way, we were made to hasten to the Fitting Lab to suffer, once again, the hammering and all.

But, with Almighty’s goodwill, our felicity was persisted and honour preserved and Hasten (our car) was ready by the time we called it a day.

Later there were praises, applauds and flashes, not forgetting the handshake of Deepak Sir.

And here I shared one of the most unforgettable memories of my B.Tech- hood.
