Hi, I have some etch brass little levers and need to make spherical knobs on the end. They already have a circular flat disc end dia 1mm but its flat, I need it spherical. Best so far seems to be Aliphatic Resin which has more body than white wood glue, 5 dips into it and the knob looks really good, right size etc. and spherical (ball shape) BUT..after its dried its the same diameter as the disc end still but only now half the diameter sticking outward from that, and with more body at the top, not symetrical anymore but more like a hot air balloon shape ! Dipping again makes it look good but the same shrinkage gives it a similar though better form but its also now too big as you can see the etch brass disc within the translucent amber shape and not at its edge.
I need a glue that when dipped into, takes on the spherical shape and keeps to that as it dries. no shrinkage !
Also need to see whats happening when dunking so a coloured glue would be useful. This would also be great for making flat unrealistic etch brass representations of railings and rods etc, into something circular section again.
