I'm helping a neighbour with her iron (just post-war) garden gate. The top of the gate is held by a u-band bolted to the gate post. The lower end of the gate has a pointed pivot which goes into a hole in the concrete path and over the years it has ground its way down so the gate scraped the path.. I've done a temporary fix with a pile of 5 2 pence coins in the hole which raised the gate the right amount and it it now looks right. But what should be in the ground? I would expect an iron cup or capped tube about 1 inch in diameter. The school gates opposite have the same system (big double gates) but I cannot see what is in the ground.
Does anyone know?
