personally don't see any use for the Tichy rivets except for bridges.
The .025 rivets would scale out to 2 3/16" in diameter, while a 020"
rivet, if he makes one, would be 1 3/4". Most rivets on freight cars
have heads smaller than 1" in diameter.
For comparison, the rivets on the old Rivarossi Pullman cars were
.016" in diameter, and I think most would say they were bordering on
the "grapefruit" appearance... maybe more like a nectarine :-). On the
Accurail kits I've designed, I usually specify a .011" hemisphere not
quite half its diameter high, so the resulting rivet is about .010" in
diameter, or a scale 7/8, and some manufacturers have gone smaller
There are smaller brass rivets available for military modelers, but
they're not cheap; about a buck a dozen. Smallest I've found in this
country is .016 heads on .012 shanks. These mount in a hole drilled
with a #80 drill. These were a good match for the above mentioned
Rivarossi cars, now no longer considered state of the art. I've found
a source in Germany that has brass rivets with 0.3mm heads on 0.2mm
shanks; that's .012" heads on .008 shanks, but that means you need to
deal with a #90 drill or thereabouts. They will fall straight through
a hole drilled with a #80 drill. You don't want to ask the price :-(
