All Done!  Pretty happy with the final outcome of the Certiflat Welding Table kit.  Took a bit of help from their support for me to get it flat but other than that pretty nice addition to the shop.  Working on clamps now, I am turning down some 3/4 (don't have any 5/8 lying around - and I have a lathe) for the pins and attaching some cheap harbor freight quick clamps to them - proto-type seems solid enough - usage over time will tell.
