Hi,

I have an application - I would like to use a porter cable style collet to both lock the collet into place such that I can position it anywhere along a long aluminum rod, but when loosening the collet it would freely slide along the rod but there would be no wobble between rod and collet. I don't need steel because this is not a high speed or motorized application, just a simple fixture device for use on a table top. Can anyone reccommend any companies where I could buy them off the shelf? I will be using somewhere between 1/2" to 3/4 inch alum rod. I could even settle for plastic or composite as long as it is rigid...
