Tank flanges now fit together light tight…that is less than 0.001" I believe that is about the minimum gap light can be seen thru (or so I understand) True of not, the seam is more than good enough to reseal.
Interesting project that salvaged a prewar Kiekhaefr single cast aluminum tank. Learned a
a new skill and used a surface plate and a trash find mirror.
Problem with Wet or Dry and spray adhesive is neither holds up to water.
Next time I would like to see how valve grinding compound works for this purpose.
Due to limited area provided by 2 sheets of sand paper, it was not possible to really figure 8
I did vary direction as much as possible. Results more than satisfactory.
A "short version" posted to Tools of Trade site for future reference.
Will also post a how to for resealing cast aluminum tank.
