I posted this on the tailed side and decided to post here too. Hope I don't get in trouble for double posting. But I thought some might be interested.
True parallel clamps are not hard to make. Just some scrap pieces of 1/2 thick oak with 2 holes in them.

Some ordinary pipe clamps, and walaa true parallel clamps that actualy give pressure in the center of the board and the pipes keep the bow out.

This is one of two purpose built parellel clamps I made for my mid 1800's demo shop.

I did at one time see some jorgensen pipe clamps that were made like mine.
FWIW, I have been known to cut plastic pipe into different length and slide over my pipe clamps to keep them from marring or staining the wood, different lengths means I can always come up with somewhere close to what I need without cutting more pieces.
