Brian,

Someone has to help us with "spiritus" and the right translation. Cutting oils I use for steel.
Spiritus is a normal "household liquid" (my coal English!!) to clean windows, it's a kind of (95%) alcohol.
In the Netherlands "spiritus" is also used in little burners for (cheese) fondue.

The saw blad is only 0.0135 inch wide (0,34 mm) so it cost me nearly no power to saw, only time, one quarter of an hour for this piece of material.
Of course you also can use or try other tools/saws, whatever you can handle.
With my saw I can make curves.
