[member=4826]suds[/member] -fair enough question. Most telling that just recently a FOG member offered his QWAS Square and his WP Track Square for sale. I was curious what was behind that so I reached out to the seller. He told me he didn't need them now that he has a GRS-16 from TSO [big grin]suds said:How is this different from the Qwas square?
Both of those earlier products have the same shortcomings and the dissatisfaction with that concept drove us to develop the GRS-16 solution which is now well accepted.
The biggest issue is that the QWAS concept is not itself a square - it requires a precision Triangle or similar reference square to compensate for the slop between the Track t-slot and the hex bolts in addition to the slop for bolt clearance in the square.
