I’ve been using a trick similar to the Bar Clamp Hold-Down tip (Dec/Jan 22), but less destructive to the clamp. I drill out the rivet at the end of the bar so I can remove the handle end. Slip the bar through the bench dog hole from below, then reinstall the handle above the table. I replace the rivet with a spring clip to keep the clamp parts together. Changing positions is a little slower, but clamping through the table means no chance of slipping.
