I have recently bought a Delrin Anticlastic Stake, but am having trouble keeping it secure in my vice. It tends to tip downwards on the end that I am working on and I wondered how I should best set it up to keep it in place. However tight I do it up, it still slips out of place. My vice is old, so I have tried a friends vice and the same thing happened in that one. Is there a foolproof way of securing it, or a certain piece of equipment that works best? At the moment I am unable to use it as it won't stay still for long enough and I have to keep tightening it up, only for it to work loose after a few hits with the hammer.
Any suggestions from people who work with this tool effectively would be gratefully received. I am so looking forward to using it properly!
