00:00They're going to have something similar, a similar stage, a little more organized, we're going to distribute things better among the counters.
00:08What was the first thing we did? We started with the butt, right?
00:12We identify the graininess of the cylinder head, so that it has no buckling.
00:17We did it with some reference measurements that were, with the thumb rule, supported on the edge, right?
00:24Right? Along the stock, we tried to find several reference points, along its length, so we could have good reference points there.
00:34We also did it width-wise, and that was the first measurement I took.
00:37We could measure across at several points on this stock, right?
00:43Yes, for what it is.
00:48Yes, I am showing the ruler positions.
00:51Now, to know if this stock has light, or not, between the hair ruler and its surface, we use the edge that is here, over here.
01:02The dimensions and maximum clearances are always indicated in the engine construction manual.
01:11We used as reference dimensions, in width, a thickness of 0.03 millimeters.
01:19In this case it would be the thinnest throat of this fire we have here.
01:25A little bit that is cut, that's why it's a little bit, some two points.
01:32Tomorrow was good.
01:34In the end, it's not going to end like this.
01:36Already?
01:37We have a little screw and if you are about to tighten the throats, you loosen them like this.
01:41And we started to verify here.
01:47If it enters the throat, it means there is a small deformation, we have light.
01:54So.
01:54Point 0.03 millimeters.
01:58Point 0.03?
01:59Yeah.
02:00Point 0.01?
02:00Oh!
02:01Here it was point 0.09.
02:03And finally, with the ruler crossed, point 12.
02:08That is, here point 12.
02:10The sum of the previous bombs.
02:13Already?
02:13What else did we do to this stock?
02:17We did the hydraulic test.
02:18We are not going to evaluate that.
02:20Camera volume editing.
02:22But yes, for example, through the internal micrometer,
02:27we are going to measure the section step.
02:29The intake hardness and the exhaust hardness.
02:31Remember that this micrometer, the only difference it has is that the numbers on the vernier go down.
02:41Here we have the larger number, here it goes with the smaller number.
02:45Already?
02:46And the equal numbers are on the back of the drum.
02:49Because this, unlike the outside micrometer, opens as I unwind the drum.
02:56Already?
02:57And this one is closing.
02:58That's why they go backwards.
02:59What we are going to measure here.
03:05Ah, before.
03:07Important.
03:09If you are going to use any measuring instrument, on the day of the test, first make sure it is calibrated.
03:14And if it needs to be calibrated, they're going to have to do it.
03:18How do we calibrate this?
03:21We close it completely and the zero has to match.
03:25Already?
03:26We have the brake here and the ratchet to finish the measurement adjustment.
03:31We measure just before where the seat begins.
03:37The seat is the angle that we are going to cut in the nozzle, where the valve rests.
03:43We don't measure that, we measure the cylinder.
03:45And apart from the stock.
03:48The intake duct cylinder and the exhaust duct cylinder.
03:53We finish the adjustment with the ratchet.
04:00We put on the brakes.
04:01And then we would be able to read the measurement.
04:04Please come closer and see where the tweezers are resting.
04:07Thank you.
04:08Thank you.
04:09Thank you.
04:10Thank you.
04:11Thank you.
