fizzy, you could do as I did (mine were 1/16"
, take two bits of steel scrap, say 1/4" thick, clamp them side by side, and drill a 1/8" hole at the joint, and countersink it, drill through a couple of locating holes, then using 1/8" copper wire, away you go, clamp it in the vice, and whack it with a hammer, one rivet, start again—boring, but cheap.
