my attempts at homemade luthier clamps

LOL! Perhaps the picture is misleading....;o)

I just started #4 and I don't own any cam clamps.

Have you thought about building a go-bar deck? Or is there a space in your house you could use as one? (...am looking at the area under your kitchen cabinets...)

I've cleared out space in my basement and there's an area on my workbench where I could approach a go-bar deck from two sides - plus I've heard of slick tips of mounting the deck on a swivel stand but I haven't had the need just yet. The real issue is humidity - my workbench is across the room from my heated forced air furnace and the RH drops below 30% in the winter months. I wouldn't mind building a go-bar deck if I could do it cheaply.
