Back From the Dead
Hey guys, it's not dead yet!!! Not only that but I've actually started making a little progress again.
Last weekend I flipped the frame over and quickly laid out the axle and the trailing arms. This was just to see where everything was going to land as I start getting familiar again with what I was thinking a year ago. I currently have handed the four inner brackets for the trailing arms off to the machinist at work. Those four brackets just need to have a 5/8" hole drilled in them to locate the inner joint. I could have just done it in the drill press, but with the trailing arm suspension I'm trying to get things as accurate as possible from the get go. My hope is that by doing this I'll have to do less adjustment and alignment once everything is together.
Today I dug in a little deeper and started actually making some progress. Originally, I had planned on making the box 78" long x 42" wide x 30" tall. As of today these dimensions are fixed, but there was one small change. The height of the main box went from 30" tall to 36" tall. Yes, this potentially can raise the center of mass of the trailer. I'm not concerned though. Proper planning and loading of the trailer will negate any negative consequence from making it 6" taller.
Another executive decision was made in how the interface between the main box and the trailer frame will happen. In the past I've just used the trailer frame as the base of the main box. Because of the complexity of the trailing arm / air bag suspension I've decide to build the main box as a unique part that gets bolted to the trailer frame. My intention is to never have to separate the two once I'm finished, but should there ever be a need to do any work on the suspension or repair / modifications to the brackets or frame it would be so much easier if the main box was out of the way. With this in mind I welded up a base perimeter out of 2" x 1" rectangle tube.
Plenty of clamps and plate steel were used to align the base perimeter of the main box with the perimeter of the trailer frame. Doing the welding outside, I had to be fairly selective as to when I chose to pull the trigger on the welding gun. From time to time there was just enough of a breeze to really mess with the shielding gas as I was trying to weld.
With the base of the main box welded up I started on the side frame of the box. With the base made out of the 2" x 1" rectangle tube, I moved on to using 1.5" square tube for the remainder of the main box structure. Unfortunately, I only had enough tube on hand to get the passenger side wall framed in and welded to the base. I'll have to grab another stick of the 1.5" square tube and the 2" x 1" rectangle tube some time this week so I can continue on with the main box while I wait for the suspension brackets to get machined. The last thing I want to do is put this on an extended pause again.
Once I do get the sticks of tube I'll get the main box structure finished off. After that I have two sheets of 16 gauge metal that I'll start wrapping the box with. I'm excited to get the box done so that I can start designing everything that will be going into the box. I've got access to my buddy's CNC router and I can't wait to start designing the slide out kitchen and then see it jump off the computer screen with a few clicks of the mouse. Until then....
