Week 3 of LTT is filled with doing a particular assignment! That is the drill panel assignment! This project will test our skills we have aquired from the first two weeks of the training. At the same time, this assignment will also impart new skills to us.
We were given a piece of steel block each measuring 15 x 81 x 121 mm.We are required to cut/file it to dimension of 15 x 80 x 120 mm.
We need to file the slot flat and this is tedious! It is a tedious process as it has to be handled with extereme care cause it will get oversized if we are not careful. So we got to use the small file and file carefully.
The result after all the major holes were drilled and the slow is file flat! Ever wondered how we drill those holes?
With the help of counter bore and counter sink, we can drill holes that are slightly more special!
Drill bits of different sizes were used! (3.2, 5.0, 5.7, 6.4, 6.8, 7.7, 9.7 mm)3.2 mm are used for pilot holes!
Reamers! They are used to make holes smoother!
Counter bore are used to enlarge a hole up to a certain depth!
A conical hole is created with a counter sink tool! They are usually used when inserting flush head rivets!
What are all the small holes being drilled for?!?! They are drilled so that we can chisel the excess material out!
Ever wonder how we created that square dent?Let me show u a short video on how we do it!
That is how hard we must chisel to get that steel part out!
These are the GO NO GO gauge! They are used to check for the dimensions of the holes.
This is how we test whether the hole size is perfect or not! ^^Now I will show a video of some of the techniques we used for this assignment!
We have sawing, filing, chisel and drilling!
Last but not least, I will show you our progress and actions in the workshop!
Like I mentioned. Mr Zahir is a good instructor! He also emphasize on good workshop practices =)
He is also guiding students along patiently if any problem is faced!
Good workshop practice by wearing goggles even when deburring the workpiece!
Breaking of this file is no joke. It requires great force! But we did it! ^^ The file was broken while filing the slot of the drill panel halfway =pLast but not least...
Housekeeping is always very important! Keep that in mind! ^^-PeRrY-
i make same traning at the LTT and remember well the Hydraulic jack, and the all other parts, they build all the same parts again and again at all trainings (aircraft mechanic and structure mechanic) these parts belong to the basic training at lufthansa.
