33 Coupe Interior 33        10/10/04

To make sure that both pieces were the same, I clamped them together and then sanded them. Now that the pieces are the right size, let's weld them in place.
 

 

 

To weld this together, I first tack-welded each end and then tacked the middle. I then put more tack-welds in the middle of those and repeated this process till I had a tack-weld every two inches or so. I then started welding on one end and joined the first tack-welds together. For the next set of welds, I skipped the next tack-weld and started on the following weld. The reason for this is so I don't warp the thin material as easily. This seemed to work pretty good as you can see. 
 

 

 

What I'm doing here is putting a baffle in for the fuel sending unit. This will help to keep the sending unit from bouncing around so much which will keep the fuel gage from moving to quickly. Notice the ends aren't welded to the back or side. This is so fuel can get inside the baffled area.
 

 

 

Now that the inside is finished, it's time to put the top on it. The first thing I had to do was to make sure that the top was square with the back. If it's not square, I might end up with the top being to one side once I got to the other end and then it wouldn't fit so this was a critical step. Once I had the back square and tacked in place, I used an old motorcycle tie-down strap to slowly bring the top in position while I welded. It was like a third hand helping me which worked great. I added one to the bottom as well and then tack welded at one inch intervals. When I had two tack welds on one side, I turned the tank over and tack welded that side like the other side. I repeated this process till I had the whole top tack welded together. At this point, I was ready to fully weld the top but only did one inch sections at a time because of how much heat was being produced. I thought that using this thinner material would be a plus because of the weight savings but I found out that it warps VERY easy with just the slightest amount of heat. If I did it again, I'd use at heaver material.
