      I was going to ask you why you didn't just use the plasma cutter to make the cutouts, but then i popped over to check out your website, and thought "ah hah, he sure does like precise, quality work." That is some nice work done at your shop.

          Thanks, but that is not my shop, all the work done is at my house in my garage. I consider myself lucky.

            Nice job. If anyone noticed in the finished pic he used a chain link welded to each upright on the bed side to tie stuff to. These are cheap & work great. Always a good idea to add acouple to a project like this.

I cut the uprights out of 4x2 rect. 10gauge. I also cut the mounting plates for the bed. I had all this steel laying around. I already have the expanded metal (cage) to protect the glass laying around. I need to get a few feet of more 4x2 and some 3" flat. Here are some pics of what I have done so far.


              I was able to find the angle of the cab with this great tool. Digital anlgle finder.



              Then I cut calculated how high I want this thing to be and cut the uprights to the proper angle. Remember you are cutting from 90 degress. I wanted the uprights to be at 72 degrees so I made the cut at 18 degrees.



              Here is the upright.




              These are the 12x5x 1/4" base plate. Notice the holes in this stuff, again more scrap. These plates cover up the front stake pockets. So I will machine a hole in them so I do not loose the functionality of the stake pockets.

              I really appreciated your explanation of the process of finding the cut angle for the uprights.Can you tell me what the cut angle for the top of the uprights were? Thanks Mike

                I really cannot remember as I write all the stuff down on my steel bench and then clean it off. But using angles: If the angle on the truck bed up right is 72 degrees then the opposite should be 108 degrees. 72 + 108=180.

                However this means that each of the angles for the top piece should be
                108/2=54 degrees each, but you are calculating from the included angle which is 90. So 90 54 =36 degrees. I think this is what I cut them for. This is why I did it in wood first.

                    Hey guys;

                    Truck bed upright = 72 Deg.
                    Bottom cut = 90Deg. - 72deg. = 18deg.
                    Top cut ( compound angle ) = 18 deg. + 18 deg. = 36 deg.

                    Same Result, Different route !

                    ........... Norm

                      Truck Rack Project

                      T.J.,

                      Your project has got to be the best documented, photographed, and explained project I have ever viewed on this site!

                      You took the time to show every detail. You are indeed a very well qualified craftsman!

                      I enjoyed viewing the progress and reading your notes on how everything went together.

                      Congratulations! Excellent work!

                      Steve

                        Hi Norm,So for the top cut is the upright cut at 18 deg and the horizontal matching piece cut at 18 deg for a total of 36 deg? I just want to be clear.Thanks Mike

                          Crawdaddy Hi;

                          Yes, The Bottom cut is at 18* to give you a 72* angle on the Upright !
                          On the Top cut each One @ 18* to give you 180* or Horizontal ! ( 36* Compound Angle )

                          Crawdaddy, in otherwards you make Three Cuts @ 18* Each , That's Per Side of the rack !

                          .............. Norm :

                              Norm, You better go back to school as your dimensions don't work! If you cut them all at 18* then the top bar would be pointed up in the air as you only have a total of 54*. If the bottom cut was 18* then the total degrees needed at the top for a 90 is 72* which is 90* less 18* = 72*. So you would cut the top of the upright at 36* & the end of the cross bar at 36*. Adding it all up would give you 90 degrees. This would be for one side.

                                Hehe. This is what I stated in my first post.


                                TOP Cut: 108*
                                But this is a compound miter cut on 2 separate pieces so 108/2=54* but you
                                need to subtract from the included angle which is 90, so 90*-54* = 36*, thus
                                both pieces will require a cut of 36*.
                                ___________
                                72* / 108*
                                /
                                /
                                /
                                108*/__72*

                                Bottom Cut: 90*(included angle)-72*=18*(this is what the bottom tube is cut to)
