For some reason the welding table is not imparting good ground to the work

So, if the welder and the welding table are stationary (have not been moved is 6 months or more) would it be a good idea to run a grounding clamp to the welding table and bolt it to the table?

Or put a terminal on the end of a short piece of welding cable and bolt it to the welding table. The other end of the short piece of welding cable would have a quick disconnect to fit the welding lead.

I know, KISS and simple is best, and this is getting complicated real fast.

I have checked the lead connections (good contact at the welder, grounding clamp and stinger), used a grinder to get bare metal at the ground connection point, and even wire brushed the slots in the stinger. That leaves the problem at the table / project contact point. Or am I missing something?
