Good point Silvershooter, most of the plans I've seen mention that and I'd forgotten it. Thanks.
OK, I'm gonna throw the other pics up here. One thing I wonder about "your" opinion on, is will it handle "full length" staves? I'll point out certain aspects/features as i post pics.
With legs inserted and screwed in (you can see where Angie formed wooden threads on the tops of the legs.) Views from both sides, and on one side (2nd pic) you can see a small handle (bar) to screw in, locking the clamp position, after using foot pressure - I think one may still have to maintain foot pressure while working but, if you loose it, the adjustment will surfice to hold the work in place untill you get back on the foot bars - not sure about this aspect yet.
BTW there are only two metal parts: The adjustment threaded rod just mentioned, and an "eye" for the wooden pin holding/hinging the top and bottom parts of the bench, near the front.
This next pic shows a nice Hickory handle locked in place (for demo). Buzz broought two of these hand picked handle but I won't use them soon as they would need to be spliced or a take down made - and I'm not any where near up to that yet. BTW, the bar that presses on the "stave" top has a notch in it and rotates so you can use the notch or a flat surface clamped against your work piece.
This next pic shows me sitting in position (I think), again for demo:
Three more pics in next post.
