I cut off a couple of inches off the fillet tube and install the cap with ProSeal.
I began to rivet the tank lids using a vise grip. Then I experiemented with making a tool to squeeze the rivets. (a rivet squeezer costs around $240 and I only need to squeeze a small number).
I glued a small piece of metal to a 'C" clamp to press the rivet together. I worked poorly and broke free.
Then I tried two pieces of steel sandwiched together but the force require bent the steel plates. I guess I could redo them with thicker plates, but decided just to use vise grips instead.
