Very nice table, wish I had one. "Platen table clamps" perhaps? Those
clamps are fancy, the last time I got to use one of those tables, the
clamps were a simple "J" bar of sorts that held planty tight just
dropping them in place. An extra tap with a hammer made them immovable,
and an appropriately directed hammer tap was required to remove them.
Don't buy them, fab them. I have a friend with an acorn table and he

Eric advises that his table has 1 3/4 square holes so if yours differ

pipe. The ones with 11" pipe will hold 6-7 inches.
He has made some screw clamps like the one you showed in your original
post but he says the pound in DIY ones he made are often faster and
It kind of looks like this:
