Stone Sculpture Power Tool Options


Electric Tools


1).
Electric Drill - buy cheapest, faster RPM possible because you will burn it out.
It can be used :
To drill holes with masonry drill bits
With carbide and diamond burrs for slow removal of stone if you don't have a die grinder
To sand with "stick and sand" padded sanding disc pad (use additional rubber cement to glue disc to pad) (local hardware store) good for sanding large areas. Use 4"or 4 1/2"pad.



2). Electric Die Grinder ( Makita makes one for around $100 Amazon.com) can be used:

Used to remove stone in areas where breakage is a problem and to carve the form.
1/4" shank size ....for most work
Used with accessories: Carbide Burrs and Diamond Burrs good for carving - coarser grit the better- AND rotary chisel to remove large amounts of stone .

3).
Angle Grinder can be used:

* To remove large amounts of stone by cutting slices into the stone with grinding wheels or diamond blades and using a hand held mallet and chisel to knock the pieces loose. Diamond blades (Braxton Bragg, Knoxville)
* To carve and shape the sculpture (especially soft stones)using the masonry discs available at local hardware stores






4). Foredom Flexible Shaft Tool

Great for detail carving - I use the S series motor and #25 handpiece but they may have a more powerful one now - Accessories include steel, carbide and diamond burrs. Will take 1/4" and 1/8" shanks. I tend to use only the smaller burrs for detail work.

Pneumatic Tools

1).Handpiece or Hammer

1/2" to 3/4"shank - needs at least a 2HP compressor to use.
3 1/2 HP better. There are three brands most used. Italian (Cuturi) (Milani) and American.(Trow and Holden). The Italian is smoother and less heavy. with less vibration. but many like the power of the American. It uses PSI from 20 to 100 (costs about $300)

 

2). Pneumatic Chisels
Tooth chisels are especially good for shaping alabaster and limestone. Points, flat chisels and tooth bullnose available. Bush chisel great for texturing marble as well as stone removal.. Carbide tipped last longer and are more expensive. They are a must for marble.
