A different QC Toolpost

Hi Bill,
Thanks for the comments.
In answer to your question there is no need for any extra locking device as the cam itself provides all the force and security needed.
I have used this holder for many years sometimes on heavy interrupted cuts as well as parting of and it has never loosened in use.
Indeed I have kept the clamp lever short to avoid to much force being applied.
It grips so well that sometimes it is necessary to give the end of the ram a bump with the hand to unstick the holder.
Hope that helps.
Alan
