Students for the RAF fuel tank replacement project could use your experienced suggestions.

I should have taken a picture of it when I was there today.
The tank was finished last semester by SDSU students.
This year's team is working on the mounting attachment points.
We can weld them to the all-aluminum tank. Or we can glue them to the tank.
You need to take into account that this is designed as a kit project and RAF's are not built on factory assembly line tolerances.
I told them it needs to be fitted to each individual ride as the gaps may be different on all of them by 1/8" or more is my speculation.
I have no real experience so if you believe we could weld the support brackets on for them and they would all fit we will do that.
My solution is to have them fit it and mark the outline on the tank of each bracket. Then take it out and weld or glue it so it fits their ride exactly. Hents the need for an adhesive in the kit.

1. The questions they ask are what aviation adhesive would be best to use on aluminum to aluminum considering our cabin hop and vibration resident frequencies.
2. I've told them we can call the manufacture and their procedures once we know the glue and then research the cost and any special equipment they would have to buy or PRA mail to them.

To the pro's is there a better way?

Not knowing the shape of the tank I would recommend straps of some sort.

That is why I wish I had taken a picture of it, Don.
I'll see if I can find one.

Crap, they are on the same USB, H-Drive as my over 50 years of economic notes. It's not being recognized.
Come to think of it all of PRA's projects are on that drive also.

Dang nothing can be easy. But have a new friend who will try and recover the data. Fingers crossed.

I just realized that of the 4 Terabytes, on the busted drive, at least 2 are PRA backup files.
Don, I will take better pictures tomorrow.
However, there are pictures I post of the project here:

Please see if you can see how to strap it so it will not wobble from side to side.

We will use velcro for padding and as a further attach point between the tank channel and the top of the keel.

Also, note that the tank is the bottom of the seat on RAF's. The new adjustable seat back design does attach to the mast but also rest on the top of the tank.
