Finding a piece of hollow brass was a piece of luck, however but the rest required a bit of ingenuity. A dremel was used to cut the 1/32" tube down the middle for a distance of 1/8". Spreading the halves made one end of the rivet. To achieve that result meant that somehow the tube had to be held securely buy not so securely that it was damaged. A pair of pliers was consideed to forceful.
Therefore, a hole big enough to accomodate the OD of the tube, was drilled in aluminium, to a depth that allowed the dremelled end to poke out its full depth. The the end was spread to become the head of a rivet.
Following the spreading, the tube was dremell to a length while located in the rivet hole of the secateurs. Then a slot was dremelled from that shortened end, the parts were separated and tapped down to form the second head of the rivet.
And it works beautifully
