Wow, I never used mine because of the low holding power that resulted from the lack of torque that I could generate.
I had considered using some channel lock pliers to do just this but was worried that the thin pin/axle would not be up to the task of handling that pressure.
Any issues?

Forgive my ignorance, but what is the benefit of having this over a traditional holdfast you whack with a mallet?

Nice solution. But I see that a wooden knob could also be made to just slip over the brass knob.

Philip, I believe that you are looking for a solution for the wrong problem. Plus you may damage the hold-down with the extra down force.
I rarely ... never ... need to crank down a hold-fast, whether it is this Veritas or the Gramercy (which some complain about slipping in the bench hole). In both cases there is usually a simple explanation, and it is about set up, not the tool.
In the case of the Veritas, I see two possible issues that can affect the holding power. The first is whether there is something under the foot (that section clamping the tool) acting as a non-slip? I glue on leather. The second is whether the bench top is too slippery to prevent the work piece from sliding? Many smooth plane or sand their tops and then add a thick finish, and even wax it. My bench top, after surfacing, was finished with a toothing blade to avoid a smooth surface. This adds a little grip. It was finished with a single coat of Danish Oil - just enough to not to permit glue, etc to sink into the wood. For my bench, work holding requires very little down force.
I recently made a very brief video of using a Gramercy. It is not the Veritas, but you can see the low down force needed ...
