Another one to play with:


There are 2 main types of '''Rivet'''
* Solid metal rivet, fitted by hammering
* blind hollow rivet
There's also a type that I have used in the past that have a domed head and
a shank with a grooved twist (like externally rifled solid rivet) that are
simply hammered into an accurately sized hole through the two pieces of
metal. The end is not hammered over.
Just did a google for hammer drive screws and came up with

Ah, that looks familiar. Glad you remembered, it was in the early eighties
that I used them - around the smokebox of a 5" gauge Simplex loco that I
was building with my father. It's a pity we never finished it - we got it
running on compressed air, but didn't trust our silver soldering skills and
couldn't afford to buy a ready-made boiler. I did suggest that now he's
retired he should buy a boiler and get it finished for my kids, as we've
got a handy 2200 foot track (that I helped build) less than half a mile
away from here.

I would urge you to get the original boiler up and running. G Dad will
impress his g children all that much more. If you fear the boiler may
explode, get some good quality hard plastic between the engine and
observers, or take them back quite some way and just protect the engineer.

2200 feet of track? What is the first 2 of your postcode? I have never
heard of that much track being available.
