Nylon pins

Quoted text begins.How do y'all feel about using nylon pins and epoxy instead of rebar, steel
rods etc. to set stones, and statues?
End of quote.

I would stay away from pins made of anything other than bronze or
stainless steel because they lack the shear strength of those metals.As
mentioned in the tornado post,stonework can get knocked around and you need
something with reasonable shear strength to withstand those forces.

I would stay away from aluminum because it has a lower shear strength and
it will corode and swell under the right conditions,just like rebar.While
aluminum will not leave a rust stain it will swell just like iron does as it
oxidizes.Look at the screws holding any piece of aluminum hardware on any of
the older boats in salt water and you'll see what I mean.Think of what that
white rust will do to soft stone.

On the tidal cove where I live the survey markers are driven into
granite ledge.The markers used by those who planned ahead are bronze(mostly
old boat hardware,like prop shaft or long bolts) bedded in lead.Some have
been around for more than a century or two of Maine weather in close
proximity to salt water,a time proven method.
