Crockets and finials for Aachen Cathedral

Two new finials for the Aachen Cathedral in Irish bluestone

For Aachen Cathedral some pinnacles had to be replaced. The old ones were worn and had cracked because of rusting iron and because the layering of the stone was not properly applied. The deposition direction of the stone should preferably be processed horizontal, otherwise there is a risk that a long vertical slice breaks off. In this case, they applied it vertically.

The material for these pinnacles is Irish bluestone. It is …Read the whole article…

Removing a pedestal with the concrete chainsaw

Last Wednesday I was at the gardens of Estate De Schaffelaar in Barneveld, the Netherlands.

I've arrived at the point where I can cut the openings between the ferns. It's just that some of the openings are so narrow that a normal angle grinder doesn't fit in between. Fortunately there are several solutions:

-or an Husqvarna Cut-n-break saw. This one as well is available on petrol or electrical. …Read the whole article…
