I placed the tank in through the front of the tank former and sat it in the cradle and put it under the wing tube as it would sit. Then, I had my wife hold the tank centered in the front former making sure the vent in the tank was facing up and I used medium CA and kicked it to tack the tank in the cradle in place. Then, I removed the whole structure and used Hysol 9462 to run a bead around the tank and brace, filling in the gaps between the tank and cradle. This worked very well.
