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.
