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.
