WHAT IS A SOSGA?

Designed for knife makers and blade 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 linishers using a SOSGA tooling arm to suit your model.

MAGNETIC CHUCK

The magnetic surface grinder chuck comprises a CNC machined aluminium 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 workpiece coming free).  

CONTACT WHEEL

The 5x2.5" (125x62mm) contact wheel is made from a precision CNC machined hub coated with a medium (90 shore A) polyurethane rubber. Being a stiffer and wider wheel it gives a great finish but whilst still giving accurate, flat results.

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 aluminium 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 aluminium 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.

Precision Time saver

The SOGSA is a game changer. This saves me so much time in getting the flats even between both sides. Grinding a tapered tang was perfect first go, instead of spending hours trying to get it even on the disc. And because its an attachment for my SM48, it doesn't take up much space in my tiny shed.

Surface grinder attachment for the Shopmaster 72

Great addition to the Shopmaster 72 inch grinder. Beautifully made and well designed, you pay for what you get and this delivers. Early days in terms of actual use. I have trued in the surface cover plate for the magnetic clamp and partially ground a large knife with it, that I had attempted to hand grind before this arrived. What a time saver and the results are awesome. It’s a very good thing, get one if you can !
