I recently purchased two of the Crucible holdfasts, which fit a 1” hole. Impulse buy, etc….I earlier was gifted a pair of Peter Ross 3/4” holdfasts. The Crucible HF’s look really cool and apparently hold very well with their untapered shafts, but are, well, big, and heavy. Having said that I’m pretty certain they will find a place onto my bench.
In what may be a first, I’m planning a bench build based on already owned hardware😄
My top will be fairly thick, maybe 4-5” and Roubo style.
Is there any role or reason to combine and use both holdfast sets, with both 1” and 3/4” holes and if so what pattern? I anticipate also needing some 3/4” holes for planing stops, maybe others. As of right now only planning a leg vise and no end vise, or row of dog holes.
