Just when I thought this was going to be the least popular post in history...
No, I haven't built it....yet.
I was hoping for some feedback before launching headlong into it, but in the light of the overwhelming popularity of it as a project, will probably just go ahead and do it over the next month or two.
It reads pretty well in the original article, and should give a lot of flexibility. If it doesn't work well enough it won't be too hard to pull out the clamps and install "proper" vices, and since the timber is free I have nothing to lose.
Will revitalise this thread when I get going.
Cheers,
