WHAT
IS A SOSGA?
Designed
for knife makers and black smiths, the 84 Engineering Strap on Surface Grinder
Attachment (SOSGA) makes grinding distal tapers and tapered tangs effortless
and repeatable. The level of precision achievable with the tool also makes it
great for flattening blanks and billets, removing scale after forging and
grinding stock parallel and to a specific thickness (great for making folding
knife parts).
COMPATIBILITY
Our
compact surface grinding attachment is fully compatible with your Shop Mate
48”, Shop Master 72” or Gibson 72” belt grinder using the included SOSGA
tooling arm (simply select your grinder option at checkout).
MAGNETIC
CHUCK
The
magnetic surface grinder chuck comprises a CNC machined aluminum billet body,
twenty high strength neodymium magnets, an easy-to-clean stainless steel chuck
face and an adjustable safety stop at the base of the chuck (we recommend
leaving this set 1-2mm above chuck face to stop any chance of work piece coming
free).
ADJUSTABLE
TAPER ANGLE
Setting
taper angle is achievable simply by using shims – just loosen the locking
handles, insert shims, and re-tighten. Included in the SOSGA user manual is a
guide on how to calculate correct shim size for different angles and blade
lengths.
EASY
DEPTH ADJUSTMENT
Depth
adjustment is made using the knurled aluminum knob. The fine thread and
oversize UHMWPE nut allows for smooth, acute adjustments and will hold in any
position without the need for a locking mechanism. The Strap on Surface Grinder
includes a dial gauge bracket and base plate, designed to fit any standard
8mm-stem dial gauge, making it easy to achieve precision thicknesses.
PRECISION
TOOL
The
UHMWPE internal wear components insure tool longevity, smooth operation, and
extreme rigidity. High accuracy ball-bearing linear rails are used for the
sliding mechanism and the 6061 aluminum contact wheel is coated in a highly
durable 90 Shore A polyurethane rubber compound that provides minimal surface
distortion whilst having enough flexibility to achieve a great surface finish.
The tool is designed to achieve grind accuracy of <50 micron, making it
suitable for a variety of precision applications.
