I am building a retaining wall for which I need to build 2 right-angle
I would like to cut the stones very precisely, so that I could fit and glue
the corner stones together
Were I doing this with wood, a band saw would be the ideal tool to make such
So, is there a bandsaw that can be used to cut stone ?
It obviously needs to be waterproof to allow for water flow to lubricated
and cool the blade band
It also needs a floating deck to allow movement of the stone toward the
I saw one of these at the tool rental shop
The problem is that to do the cuts I need, I would have to build 2 different
jigs to hold the stones to cut it with this tool
The stones have a flat base, and I need to need to make cuts on the vertical
The front of the stone is neither smooth nor consistently aligned with the
other surfaces, and therefore would require shimming to make the cut
To make the side cuts, I would need to shim up the side of the stones
So this is the second fall-back choice.
A bandsaw would allow me to make simple cuts by pusshing the stone into the
blade used the saw platform without any alignement or jigs.
A far better choice
I also need a 7" cuttting face, or in the case of the above tool cutting
depth. It's borderline that the blade would reach the other cuts. Whereas
the bandsaw would garantee it.
1. It is normal for quarriers to use bandsaws. I've seen rows of *huge*
bandsaws cutting away at recently quarried limestone slabs weighing many
tons. Lots of noise :)
2. I've use plain steel blades uncooled to cut soft stone. The blades don't
last long but should for your purpose depending on the type of stone.
3. You can get diamond blades for bandsaws.

A diamond wire saw would be more appropriate for this. I have a diamond
band saw in one of my shops. It is fine for cutting stone up to 2"
thick, but not much good on thicker stone unless the stone is extremely
soft. I bought this machine from Vic International probably 15 years
ago. Made by a German company call Goldschmidt. It was the "3000 series,
A diamond wire saw is a much beefier machine, uses a steel cable with
diamond "pellets" or beads in either an 8 mm or 11 mm diameter, so they
cut a pretty wide kerf compared to a band, which only cuts about a 1/16"
kerf. I also happen to have one of these, called a "Lady W", made by
Candiani Mechanica of Italy. This machine would make short work of your
project, but unfortunately it is currently out of service due to an
electrical gremlin in the DC Motor control, which I have been
unsuccessfull at getting repaired. (Reminder to self, don't buy anymore
non-USA built machinery)
You are far better off doing short-radius curves than right angles.
And even if you are doing right angles, there's no reason for that
sort of precision. Unless you do the whole wall, it will
just look out of place. What do you mean "glue", anyway?
If you're using mortar, a fairly standard tolerance is around 1/2".
There is actually a non-mortar glue, comes in a tube like caulking, that is
use to glue the top "cap" layer of stone to the blocks used to build the
As to the "right angle cuts
They are really straight cuts that come in from either the rear or side
faces of the stones.
The stone is shaped like this
I would like to cut one stone like this
(not to scale)

And the other stone like this
And then the next layer would be reversed
The glue would e applied to the surfaces exposed by the cuts
Are you building an ashlar retaining wall, or gluing
polished stone tiles to an existing facade?
If you're trying to simulate ashlar, what you're
planning is going to make the corners look wrong,
and invite cracking and the base of those prongs.
Why aren't you just stacking the corner with
the corner blocks going in alternate directions,
like normal walls?
Ashlar is when you cut the stone into blocks when
you're building a stone wall, as opposed to
"rubble", which is when you don't.
When you said you were building a retaining wall,
and wanted to cut the stone, for some reason I assumed
you were building a stone wall, but apparently not.
JUst forget I said anything.
Sounds like self-inflicted, over complicated, make work project that isn't
given a second glance of appreciation to a passer by or offers any
constructional time saving advantages. I would rethink this job if I were
