Rocker Box drilling and tapping

This week I inserted helicoils in a rocker box that were stripped out. I used a drilling taping block which I counter bourd to help keep my tap straight. From this I learned how to make sure my inserts go in straight and accuratly. Here is a picture of me doing this 

There were four holes that needed inserts  I did all four the same and they were all successful from this I leanred accuracy and making sure all four bolts screwed down the correct amount. Here is a picture of all four helicoils 

 

The next thing I did was rig the front end of a kenworth t600. Here is a picture

From this I leanred that using the spreader bar is my favorite way to rig it helps keep everything even and straight. I leanred how to calculate weight approximations of different parts of a truck. 

Micrometer reading and drilling

This week I learned how to read the micrometer. Because of this I was able to messsure objects accurately. I also learned the correct way to old a micrometer so that I have good mobility and looks professional. Here is a picture...

The bottom picture is how I added all the numbers together. From this I leaned how to read the lines on the micrometer, and my reading turned out accurate same as a digital micrometer.

The next project I did was using the drill and magnet I drilled a hole into the frame of truck. Because of this leanred how to use the tool (drill), lining the hole up accurately sitting the magnet so the drill holds up. And then also to Lube the drill pit up as well. Here is a picture...

In this picture the drill is exactly where i want it to make a hole with the magnet grabbing the frame.

You can see the hole that I made in this picture.

Rigging

This week I focused on lifting or some call it rigging. We lifted four items one Detroit 60 series engine, cummins n15, cement block, and forks off of a forklift. Our crane is rated at 6 tons. We practiced rigging to the appropriate weights, by checking safety ratings on the straps and chains. 

This was the first rigging I did. Detroit 60 Series. I learned a lot because it was my first time doing it. I found out how much I should rig for by going to the engine manufacturers website and finding out what ball park the weight of the engine is in. I rigged it for 6 thousand pounds well over the total weight of the engine which was around 35 hundred pounds. Because of this I learned how to adjust the leveler on top so that straps and chain are aligned so that the engine gets picked up straight. We repeated the same thing for the n14 but we added the weight of the transmission. And because of this I learned how to rig so that everything lifts straight up (adjusting the leveler at the top). 

This was simple by doing this I learned how to take measurements length by width to figure out the weight. And then I rigged it for a thousand pounds. Well over the actual weight. 

The next lift I did was very challenging. But I accomplished it by combining all the skills I picked up from past riggings

I used two straps which were rated for over 6 thousand pounds. By doing this I learned how to rig so that both the forks and the back side lift at the same time and go up in level. This took a while for me center the leveler but by doing this I learned to put a wrench on the back of it and level it out. Overall this project was very useful and helped me stay safe. 

Finished making the block

This week I got block finished up by putting a helcoil gard insert. Both tasks challenged me to learn new things I had never done before. I started by inserting a gard by first making a pilot hole all the way through, then making a hole the correct size. By doing this I leaned how to make a very accurate hole that is perfectly on spot. The pilot hole is smaller then the intended hole size it just helps with making bigger holes with accuracy. Then I continued by making a counter bore, by doing so I learned how to make a hole that is big enough so that you can make threads in the hole but you only want to drill down so that the gard insert still fits, the counter bore is just a guide or a way to make sure your threads are straight. Then inserted the helcoil with the special tool, then I made sure the bolt fit perfectly.  By doing this I learned how to insert a helcoil.

Making the counter bore 

Next thing I did was insert the gard. This was a lot simpler but I still learned a lot. I started by finding the right drill pit size by going on the gard spec website. Then I again made a pilot hole followed by the right size hole which was 17/32. By doing this I learned how to install this drill pit into the drill press, then making a bigger hole with accuracy. The next step I learned how to insert a gard by screwing parshally a grade A bolt onto it with a new nut. Then taking a wrench and screwing it into the hole making sure the the side that cuts into the hole is on the right side. Finished product....

2"x2"x3" Block Project

This week I started my block project. I learned how to use the hoist to pick up heavy material and parts. To start my project I had to take a metal bar off of the top rack. I first did all the measurements to figure out exactly how much the bar weighed and then I had to figure out the right equipment to lift the bar. I did this by reading the warning tags on the straps. Here is a picture of me doing this. 

Next I started my cut, which needed to be three inches. One of my class mates teached me how to use the saw.I learned how to adjust the speed accordingly. And things to watch for such as the flakes coming out from the sides the smoke making sure it does not come out excessively and to spray it with some solution as needed. Here is a picture of this.

Finshed product.

Next I began to do measurements to as where I will be putting the helicoil and gard insert. And finding the middle. Here is a picture of the gard insert 

This week that is far as I got with that project I finished up my wrench and couple other assignments. Next week I will be finished up with the block.
