Thomas Aquinas, part 2: sawing

Thomas Aquinas, part 2: sawing. Two large sandstone blocks

1. Two large sandstone blocks of Udelfanger sandstone: 1 for the statue of Thomas Aquinas, 1 for Serge's angel

Two large blocks

The work on the on copy of the statue of Thomas Aquinas has finally started. I had received two large blocks of Udelfanger sandstone some time earlier: one destined to make two angels out of it and one block from which I had to carve the two parts of the statue of St. Thomas from St John's Cathedral in Den Bosch, The Netherlands and fit them together. So the first step was to divide both blocks into two with the diamond chainsaw.

Presawing Thomas

After that I put one block on my copying saw and started presawing Thomas' lower half. The dividing line of the two parts was meant to be near the line of his hood, so that …Read the whole article…

Which diamond chainsaw for which job?

My diamond chainsaw

I recently cut up a blue block of sodalite with my diamond chainsaw. Because it's quite an expensive material, I could save quite a large chunk by this method. If I'd made this sculpture in the normal way with the angle grinder, lump hammer and point chisel, I would have had some wheelbarrows full of expensive rubble for the dumpster. So in this case my chainsaw came in handy. But I actually rarely cut up or spalt large stone blocks. I actually bought this saw for removing blocks from historic buildings, or cutting loose heavily anchored statues from their foundation.

The diamond saw I chose in 2015 chose was a Cardi Coccodrillo35. But what types are there actually, what kind of job do you use them for, and which one is the best for which job? …Read the whole article…

Crockets and finials for Aachen Cathedral

Two new finials for the Aachen Cathedral in Irish bluestone

For the 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 had to remove a plinth of Belgian bluestone, that was anchored with four stainless steel pins of 2 centimetres thick to a concrete foundation. Of course the solution was the concrete chainsaw on 230 Volts (Cardi Coccodrillo 35 so you might say Renova chainsaw). The base will in due course be reinstalled inside the main building itself, but more on that later. …Read the whole article…

Moses and Aaron-Veghel

Lambertus Veghel façade with statues of Moses and Aaron

Today I once again started on an interesting restoration job. I went to St. Lambert's church in Veghel to collect two statues: Moses and Aaron, carved in Udelfanger sandstone. The statues date back to about the construction time of the church, around 1860. …Read the whole article…

Today my colleague Stide and I were in Nijmegen again. We are presently replacing a number of ornaments on the South Portal of St. Stephen's Church all of them (20 trefoils, 7 consoles, 20 crockets and 3 capitals), and right now we're arriving at the removal of the last blocks. …Read the whole article…

Experiment with a Cut-n-break machine (video)

← To the first post about this project

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:

-a chain saw for stone and concrete (hydraulic, with a petrol engine, or on 230 volts)
-or an Husqvarna Cut-n-break saw. This one as well is available on petrol or electrical. …Read the whole article…
