I found a very nice, small QTP on eBay and purchased it. I quickly found that it needed altering to work well on my little cross slide. The bottom of the t-clamp had to be sawn off and replace with a properly sized unit. Additionally, it would rotate severely under load so I added a second clamping tang on the back of the unit to make use of the second row for a T-nut. The unit now functions quite well and is a favorite of mine for lots of operations where rigidity and removal are key.
