Been slacking, sorry all.
With EJS prep, EJS, the flatty run, and having to buy a replacement DD in there I got a few things done.
I finally got the gas tank skidplate cut and bent. It is 1/4" thick aluminum that is about 41" wide which is just to much for my press. Honestly, I had the plate laser cut with all the features I wanted and cnc bent along with shipped for less than I could get a sheet of material for locally.
The skidplate bolts to the rear bumper bracket and also has two 10mm rivet nuts in the bottom of the frame per side for weight support.
I'm still getting use to this aluminum TIG welding thing. This 1/4" stuff about maxed out my home welder. It isn't coming back apart. I am pretty sure about that.
After test fitting a few different templates for the bottom profile of the tank I decided on the final shape for the tank....
Made a print for the tank with all the bend centerline information and transferred that over to some 1/8" 5052-H32 aluminum.
Cut it out using the trusty jig saw with 14tpi Bosch blades with a touch of wax on the blade.
Bent up the main part of the tank in one go on the press brake I built a little bit ago. I was able to do all 4 bends in this design to make a complete tube with only one seam on the top front. The last bend made the ends pinch the top truss, but the material is flexible enough to allow that. Once it was bent I dropped the top truss, spun the open end down, and was able to remove it.
Overall I am very happy with how that all worked. The ends where less than an inch apart after all the cutting and bending. It was easy to clamp the ends together to get the final shape. I will be able to tack and fit everything pretty easy.
This is where I am at tonight. I was able to test fit the shape of the tank down in the pocket that the skidplate created. It fit great. I am super happy!
That is all for now. I have to make the baffles, end caps, and fuel pump mount next. Then comes lot of aluminum welding.
