I bought a set of these a while back, but found they didn't hold very well, so I fixed them up as per this video https://www.youtube.com/watch?v=S7lnfW4iT6o
Still, they "stick" but they don't hold. even if I hit them in with quite a bit of force I can still swing the board around with ease, I have resorted to using clamps again.
Now, based on everything I've read and on that video, I think hold fasts are supposed to hold much stronger than what I'm getting, right?
The round do holes in my bench are 2 1\2 inches deep, others are 1 1\4 . all holes are 3\4inch in size. I'm wondering maybe I need deeper holes? different size? I'd like to make holes on the side of the bench too and really enjoy the holdfasts, but not until they can hold stronger than a 5 year old kid
a friend of mine has a set too and they don't hold any better than mine so I don't think I got duds.
