Description

The 84 Engineering SOSGA is a compact surface grinding attachment designed for use with Shop Mate 48”, Shop Master 72” or Gibson 72” belt grinders, using a SOSGA tooling arm to suit your model. It is a precision tool designed for knife makers and blacksmiths, making grinding distal tapers and tapered tangs effortless and repeatable.

Details

The SOSGA comprises a magnetic surface grinder chuck with 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. The tool is designed to achieve grind accuracy of <50 micron, making it suitable for a variety of precision applications.

The UHMWPE internal wear components ensure 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 powder coated for durability and features zinc plated steel components, a spark guard, and a stainless steel chuck. Setting taper angle is achievable simply by using shims, and depth adjustment is made using the knurled aluminium knob.

Product Inclusions

The SOSGA includes the Strap-On Surface Grinder Attachment and sliding linear rail. The Standard Dial Gauge is sold separately.

Easy to use.
Works well. Light is bright. Our new patio umbrella does not have e a center pole, so the lights get somewhat blocked. But still pretty useful.

Sturdy & easy to move around
Its solid & sturdy. It does exactly what it’s supposed to. You have the option to fill it up with water or sand , I choose water. It holds the umbrella in place. The wheels and handle make it really easy to move around, which is a huge plus. It fits perfectly and feels very well made. Great addition for my pool area!

Heavy-Duty Base with Convenient Mobility
This umbrella base does exactly what it’s supposed to—keeps the umbrella stable while still being easy to move around when needed. Once filled with water/sand, it feels solid and secure even on slightly windy days, which gives peace of mind. The built-in wheels are a standout feature. Moving the base across the patio is smooth and doesn’t require much effort. The handle placement is well thought out, making repositioning quick and hassle-free. Overall, it’s a great balance of stability and convenience. Highly recommend if you want a sturdy base without sacrificing mobility.

The base that fits!
Finally, easy to put together and the right fit just before summer. It was extra windy so I put extra weight.
